MyLightMeter PRO App Comments & Reviews
MyLightMeter PRO Positive Reviews
Best light metering app IMOI Have used this app for about 4yrs, to meter scenes for 35mm and 120 film photography and for what it is, in my opinion it’s easily the best light meter app for IOS. Out of the 3-4 other ones I’ve tried out over the years it’s the most customizable as far as parameters and settings, you can also make custom lens profiles for quick access to locked settings, which I haven’t found in any others. It also has two different UI’s, One gives you a good bit more information like your hyperfocal distance and near focusing distance and the EV of the scene as well as being able to fine-tune and set limits on your shutter speeds and apertures. Most of all the accuracy of the meter is surprisingly good and you can evaluate a whole scene or take spot readings by tapping the area you want metered on the screen in pro mode. I have also compared with my 5d mkii meter and gotten comparable results. If you do notice it leaning more over or under exposed there is 1/3 stop Increment's of compensation +\- you can adjust in the settings. All in all a great tool for the one time price, especially if you don’t have much use for an expensive Light Meter for the type of photography you do this is definitely the best budget way to go..Version: 1.9.82
Long Exposure Life SaverI wanted to wait until I got my film back before reviewing this app. I absolutely love the design of it and handling it is a breeze. Most importantly though it WORKS. I am a film photographer who shoots landscapes and waterfalls. Long exposure for waterfalls needs an accurate meter reading. I took a chance on a $4 app before burning $200+ on a real meter and it paid off. I got accurate and *consistent* exposures across 3 different lenses and 4 different film stocks. I wish I could include the photos this app helped produce in the review because it is spectacular. Easy to use in the field with instant results and high sensitivity to lighting changes. I am very pleased and so thankful someone put this out there for such a low price. ***I would like to point out that, when compared to my camera’s self meter, it’s results were less accurate indoors. If you mainly shoot portraiture or indoor scenes I can’t speak to how accurate it will be for that, but I give it a 10/10 for natural light.Version: 1.9.8
Wow!I was a little Leary when I first found this app. I wondered how a camera phone and software could accurately measure light. After all, physical light meters are quite expensive. However after reading the reviews and looking at just a few dollars for the app, I decided to pull the shutter! I am not disappointed!! As soon as it was downloaded, I set up three different product shots in my studio. I measured the different lighting using Led always-on lights and then switched out to 2 strobes. The accuracy of this app blew me away! Out of three setups and several images captured, None were off the mark. Thank you for creating this app. I am so glad I found it!.Version: 1.8.11
Valuable Tool; AccurateI’ve been using this for 4 years on and off when I’m out shooting my manual film cameras. I’ve never had a bad exposure metering with this app! I’ve compared its metering with other in camera dslr’s and vintage light meters and it’s never been off a half stop at most, which is never an issue with post processing. I love the details with being able to have presets for different lenses and while I don’t use the hyper-focal distance readout too often it’s super handy when you do need it. For anyone wanting something quick to check metering they need not sleep on this gem!.Version: 1.9.103
Nearly Perfect!This is by far the best light meter you can get, it is reliable and has a hefty amount of features with the pro version. My main use is for my Polaroid instant cameras for manual control. It nails every photo and I am happy with this app! My only complaint is about the user interface and experience. I wish it was a little more streamlined because sometimes it can feel like a little too much when you need to adjust or change something within the settings. I feel as though with time given, it’ll be easier to navigate but as a new user, it was so confusing. Other than that, I highly recommend this one..Version: 1.9.103
(Like) the real thing!A very well thought out, usable app. The resemblance to an old style physical meter you held in your hand is not only on the surface. The visual elements all work and make this tool eminently usable. My personal way of working is very old school . I want to point the meter, and have the reading for exposure. Because of that I can comment only that used in that way this app is perfect. I really have no complaint about any aspect of it for that kind of work. In promo The ability to zoom and touch the very spot you would like to measure is quite useful and is probably the only feature that I find useful after simply taking a general reading or an area reading off of an illuminated surface. But that’s me. I did look at some of the other features, but they are not elements by myself for use. I do have the sense, taking a general look at things, that they would be as well thought out, intelligently designed, and usable as the part that I use..Version: 1.9.103
Handier than my Gossen Luna ProI use a 1955 Rolleicord V when I shoot film (Ilford HP5 - 400). I like to carry as few things as possible - just the camera - and I would often leave my light-meter behind when I went out to shoot, relying on having memorized the “Sunny 16” rule to determine my exposure settings. I bought this meter after trying the free version. I always have my iPhone in my pocket, and this apps blend of features and skewmorpic similarity to a meter I am familiar with is just great. I’m quite pleased with all the features and settings and look forward to having the meter handy always. Thanks!.Version: 1.5
Nicely DoneI am a collector of vintage photography. I have hundreds of cameras, in just about every format. I really appreciate all of them and their differences. Using this app has been a joy to use for all my toys. I, like others was a little unsure about getting the app but I heard so many great things and reviews, I figured I’d try it. Using this app and my own way of doing certain things over the years I get very nice results. It is truly a great app to have with you all the time..Version: 1.8.18
Best meter app and great support!I’ve been using this app regularly for nearly six years in combination with a Sekonic meter. By adjusting the EV setting, you can match the app to a traditional meter for even more accuracy. For the first time, after a recent update, I had problems with the app. I reached out to David and had a reply, including a work around within hours. The app was updated again within days and has been trouble free. It says a lot when a app has one problem in many years of use..Version: 1.8.7
ImpressedI was a bit skeptical at first but I just picked up a camera with no meter and needed something quick for a trip and for only $3 it was worth a try compared to buying an expensive meter. I received scans back from the lab and all of the exposures were metered exactly how I intended when using the app(used in pro mode with selective metering). I like to travel with the least I can and always have my phone on me so I’ll keep using this app in the future..Version: 1.8.22
Perfect accessory app for film photographyCan't find anything to complain about! Provides accurate matrix and spot metering. I use it with my 70 year old TLR and my 90 year old folder and get accurate exposures 90% of the time. Any misses I'm sure are down to the lack of precise shutter speeds and aperture in those cameras. So much cheaper than a separate meter and never have to worry about not having one with me. Sometimes I just pull it out and meter my surrounding to test my eye..Version: 1.9.83
Great for old camerasSo I bought a few old cameras (mamiya c220, hasselblad 500cm) and none of them have a light meter, I was going to buy a dedicated meter but they are expensive and I don’t mind it but I will not use this cameras as my main format for now, so I tried this app (the pro version because a few dollars is nothing in the photography world) and the results where beyond my expectations!! Very impressive, very simple, and is in my pocket all the time :) thank you for such clever and great app!!.Version: 1.5
Very AccurateThis is a great app, it’s right on. I’ve measured it against multiple light meters, including the excellent meter in a new leica MP and it’s great. There are a few features I wish it had, I wish I could save the measurements, lens and aperture/shutter and phone photo it’s taking, so I don’t have to keep a notebook of shots as well. I also wish it had frame lines for the lens it’s got as a preset. But as a simple light meter, it’s excellent. I stopped carrying an additional meter after testing it..Version: 1.8.11
Brilliant app, Responsive support.Recently I had noticed a to EV reading discrepancy between the classic and pro modes. David responded to my email within literally minutes and gave me some things to look at. Ultimately fixing the issue was simply deleting the app, rebooting my phone, and then reinstalling. In hindsight I should’ve known to try this first, but it was good to have a brief conversation with the developer. Excellent app, super support!.Version: 1.9.4
WorthwhileI almost never rate an app, but I felt the need to for this one. It’s an excellent and simple app. It doesn’t have unnecessary frills or try to milk money through subscriptions. It gets the job done very well. This app is also why I still practice film photography. The built in light-meter on my Pentax broke not long after I was given it. If it weren’t for this app, I would not have continued the hobby..Version: 1.9.95
The light meter is very nice!The app is super easy to use and works great! I wish it had a bit more customization options for the app’s skin and maybe some camera presets. I could set up a camera to automatically adjust its settings based on my current camera or lens settings. But I think I might just be missing something simple with the current options!.Version: 1.9.90
On par with spot meter in OM4I tested this along side my Olympus OM4t’s internal spot meter and it was spot on. Only downside is it’s kinda fussy with 200 iso on 6x7 cameras. Especially the 6x7 because it will tell you f stops that you don’t have. But that’s partially the fact that the lens doesn’t give display every f stop. Overall this app work’s impressively well. Makes film photography more accessible witch is needed with how expensive film is..Version: 1.9.8
Fantastic appI had a lot of trouble getting my account recognized at first, but customer service stepped up to the plate and fixed it. Worth it! Spectacular maps and features and definitely eclipses my old Garmin. Of course, get a battery to prolong walking around, and iPhone screens are iffy in the sun, but none of that is the app’s fault. Love it! And thank you customer service..Version: 1.9.6
Buy this appI don’t ever rate apps but as a film photographer I feel as if I have to help out this independent app developer. I do not own an actual light meter but this app gives me the proper exposure settings for 1/20th of the cost. I will eventually go out and spend the money on a light meter but until then, this app suits my needs 100%. I shoot with a Mamiya RB67 and some Canon and Olympus 35mm SLRs and this app never fails any of the cameras..Version: 1.8.11
It works but without focal length and spot metering I don’t use it anymore.I used this with a 50mm lens with good results. Im not sure the actual field of view or focal length this measures but its harder to use and more inaccurate with wider and longer lenses esp with 60/40 meters. I don't understand why the window is a circle when camera sensors are rectangular. The app I use now has a slider you can change the focal length and also has a spot meter to expose for particular regions much more useful..Version: 1.9.8
Tremendous supportI am new to rangefinder photography and using a light meter. I downloaded myLightMeter Pro a little while back and am now working to get proficient with it. I had a question regarding its use that I could not sort out via web searches, etc. I emailed David, the developer, and he responded in roughly 12 hours with the answer. That’s tremendous support and I wish o could vibe him 10 stars for it..Version: 1.5
Easy to useUpdate July 2019. I haven’t used the meter for a while. When I opened it this morning I hit ‘don’t access my camera’ and BOOM! Screen went black and I can’t get back to the meter. Annoying. I guess I have to dump it and buy it again. Old review when I liked this app: I have a bunch of old cameras, a couple don’t have meters so this works for me. I’m going to have my phone with me anyway so having the meter in my phone cuts down on gear. Some of these old cameras are heavy and bulky enough. DDahlberg.Version: 1.8.2
Handy when you forget your primary light meterI installed this app because I figured it would be better than nothing if I forget my Luna pro. Now that I’ve used it a while, I sometimes use this as my primary meter for my medium format photography. One of the better apps I’ve ever installed. Kudos to the developers..Version: 1.9.103
Convenient and helpfulWhen I first started learning film photography I was a little lost then I downloaded this app and my photography has changed completely. This app is user friendly!! Very easy to use and have with you at all times. You never know when you’ll need it :).Version: 1.9.82
Surprisingly accurateI tried the free version of this and was happy that my images came out looking great. So I bought the pro version because it beats paying $300 for Sekonic. I'll still use my actual light meter for bigger projects, or if I'm using strobes. But the handiness having an accurate light meter in my pocket all the time can't be understated. Great app..Version: 1.5
Worth it.The pro version of MyLightMeter is everything it claims to be, works precisely even in low light, and is very intuitive to use. The developer, David, is great too, he was willing to make some tweaks to the program just to make it more useful to me, on my request. This app is worth your money..Version: 1.9.93
Worth itJust got my photos back from the developer and they look amazing. Each photo was exposed properly! I didn’t have a working light meter in my film camera so I decided to try this app out based off of a YouTuber’s recommendation, and it works well. No issues for me. I would definitely recommend..Version: 1.8.8
Very handyThis is a great app. I’ve found it to be quite accurate. A feature I like is the ability to match the meter to specific focal length lenses. As I always have my phone with me, it saves the space that would be taken by a separate meter. The camera I muse it with is a Mamiya C330 Professional S and my normal meters are a Gossen Luna Pro and a Pentax Spotmeter.Version: 1.8.8
Excellent AppI really don't know much about photography. I just wanted an app that would consistently quantify brightness. I surely can't make heads or tails of the PRO version but what impresses me is how consistently reads room light even with the lights out or sunlight. I have that other app that gives lumens and color temperature but it is not consistant. This app is a real tool..Version: 1.8.8
Super convenient and accurateI love this app and have been using it for years! As long as I have my phone I always have a light meter. It’s very accurate, gets the same reading as my friend’s $200 “professional” meter. Works for everyday shooting and for large format work as well. Highly recommended..Version: 1.8.8
I use it almost every dayI highly rate this app which I use in concert with the Luxi incident light meter dome attachment on an old iPhone. I use it almost every day in my home tabletop studio and it is very accurate and intuitive to use, especially in the Classic mode which is very reminiscent of the Weston Master meter I used 40+ years ago..Version: 1.8.11
Works AmazingJust went back to black and white film. Once I got this light meter app it changed how great the photos are coming out. It works amazing I don’t even use the hand held light meter this is easier especially when trying to shoot quick..Version: 1.9.8
For Instant Cameras—-Update.The developer added the three Instax formats as separate film sizes!!! Perfect!!! I use this app primarily with different instant cameras including the Mint RF70 and SLR 670. Really allows me to nail the exposure and concentrate on the image. Emailed the developer about the hyperfocal distance for the RF70 and he advised using the 4x5” film size as a conservative measurement. Great app!!!.Version: 1.9.7
Great resultsI bought this app to use with my Rolleicord V, which has no built in metering. The results have been excellent, and the app was much cheaper than buying batteries for my old Gossen Lunasix. It's quick and intuitive to use, and I like the way I can tap to spot meter a point in the scene..Version: 1.9.8
Convenient appIt’s a great little app that helps take great pictures. I’ve been using it on spontaneous trips when a physical meter isn’t available. Most people always have their phone on them, why not have a quick tool to help in a pinch..Version: 1.9.83
Works great for Wet Plate Collodion as wellI found that the app has setting for Daguerreotype. Even though collodion isn’t daguerreotype it is pretty close. As a beginning wet plate photographer, I didn’t have the experience to get a good starting exposure. Using this app in daguerreotype mode, I can usually nail the first exposure..Version: 1.9.8
Excellent light-meter app!MYLightmeterPro is extremely useful for film photography. The ability to capture record shots with exposure info is essential for my use of tracking the per-shot exposure setup on older cameras with no built-in method for adding data to the image..Version: 1.9.95
Outstanding!I shoot a lot of film on vintage cameras, and I find that this meter is unbelievably accurate. I have a Luna six classic light meter which works as well, but having a program on my phone which is always in my pocket, makes this a true winner!.Version: 1.8.21
It really helps to teach how to read lightJust wanted to say thanks to the developers behind the app, it’s solid does not crash and it loads very fast without getting in my way with annoying messages or ads. Great work.Version: 1.9.82
Awesome Light MeterAfter testing the light meter through low light conditions in comparison to my Sekonic, the meter is off by 1/3, luckily the app’s settings allow you to include 1/3+ to all future readings. Sometimes I’d forget my meter at home, and this app is going to help a megaton as a backup..Version: 1.9.8
It works.I was skeptical about this product when dedicated light meters are hundreds of dollars. But, I wanted to give it a try. I put this alongside my brand new Sony A7 III and metered a few dozen locations, indoors and outside. This meter app was within 1/3 of a stop each time or dead on the money. Well worth the purchase price..Version: 1.8.8
I absolutely love this light meter but...It turns down my volume every time I open it. It’s a deadly accurate meter, my film comes out perfect while using it and I absolutely love it. But if you’re listening to music and trying to meter, it takes over the volume and mutes it. It’s a bug that’s never been fixed and it’s aggravating..Version: 1.5
A Lightmeter You Always Have On YouWith my digital and film slrs with there auto everything, it’s nice to have an accurate meter with me when I take a fully manual camera out. It’s as accurate as my Gossen Luna Pro F and my old Sekonics. Thanks for keeping the app updated. Very handy to have with me all the time..Version: 1.8.11
Works flawlessly. Game changer.I’m an amateur film photographer with a highly limited short-term memory. This app enables shooting in very odd lighting conditions on cameras with a limited choice of shutter speed (one of my cameras is from the 1940s), and removes the risk that I divide wrong and ruin an exposure..Version: 1.9.8
Good but needs moreI use this app whenever i forget to bring my Sekonic meter. It helps me get a close reading for what I am doing with my film. I just wish you could create your own profile that included limiters for ISO, Aperture and Shutter speeds as it would help between the types of cameras I use..Version: 1.9.83
Very clever appI love this app. The developer thought in everything. Very convenient to have it as part of my iPhone. I had used another for this same purpose; but was disappointed. It also has an excellent personalized support. Congratulations to David for such an excellent work..Version: 1.8.11
Fantastic.Skeuomorphic design may not be everybody’s thing anymore, but this is a marvelous example of when it works. The functionality is perfect. The interface is good. The feel is wonderful. This feels like a return to form for the App Store of yore..Version: 1.9.103
Great Light Meter AppI mainly use this app with my pinhole cameras because I can set a very small aperture, then the film ISO, and get the closest approximation of exposure time without any complicated calculations. Lots of settings makes this app valuable for any photographer. I recommend it!.Version: 1.9.83
Best Free light meter Ever!For a free app this little thing has saved me time and time again when I was trying to get just the right settings and didn’t want to carry a big bulky light meter with me. I just used my phone..Version: 1.9.83
GreatWorks as it should..Version: 1.8.4

Easy, Intuitive, use for FilmHandy for all kinds of film and all kinds of film cameras. From 35 mm to large format bellows cameras and medium format film!.Version: 1.9.7
Diffuser for incident lightingWould appreciate if the developer could recommend a diffuser for an iPhone. Not sure what to use. Impressive app..Version: 1.8.22
Bonne applicationFait très bien le travail. Facile et agréable d'utilisation..Version: 1.8.11

Very useful and accurateGreat reflective light metre..Version: 1.8.8
Love it but latest version crashes ever time I use itI tried to contact you via your support page rather than use a review to report this but it looks like your me.com account is no longer valid and I could not find any other contact info. The latest version of the app (I am using iPhone XS) crashes every time it goes to the background (including when the lock screen is used) causing me to have to reopen the app and choose my settings every time I want to take a picture which is time consuming and error prone. I use classic mode exclusively but the app always reopens in pro mode on me and sometime rests the iso value. Otherwise I really enjoy the app and hope this crash can be resolved quickly so I do not need to find a new light meter app. Thanks..Version: 1.8.2
Love this appSuper helpful! usually have no issues until today. my camera is working outside of the app but not in app. just a white screen. :(.Version: 1.8.2
Great app, well made.Would definitely recommend. Solid app. Good functionality..Version: 1.4.11
A great light meter appThis is an accurate, versatile light meter with a wide range of settings and the most analog feel of any light meter app available. Pairs nicely with an old analog film camera for a retro feel on a digital device..Version: 1.5
A+Great app . I highly recommend it !.Version: 1.5

Fab!Accurate, great spot meter, easy to use, no fuss no muss.Version: 1.4.11
This can be your only light meterThis app stays on my home screen because I get accurate results with something I always have wiith me. I like the lens presets as I can make one for each of my vintage rangefinders and if I want, compensate for filter factors at the same time..Version: 1.4.11
PERFECT!!I calibrated myLightmeter Pro to my Leica's meter. I went on a trip to New York a few weeks ago with my Rolleiflex and iPhone. This app was the perfect companion. Very happy with how it worked. It's simple with its shutter speed and aperture dials work together. Real "Old School" feel. I recommend this app..Version: 1.4.11
Very commendable light meter.This app works extremely well. I have used it next to my LunaPro and it's very accurate!.Version: 1.4.11
Better than any regular meterIt has a better range than any hand held light meter ive ever used..Version: 1.4.11
Good alternativeGreat app. Worth the money especially considering the price for a real dedicated meter. The pro version is worth it just for the fact that it remembers your iso..Version: 1.4.10
A second life for an old camera.A great app that allowed me to resurrect a great old Spotmatic. The ability to set profiles to match your lenses is great..Version: 1.4.10
Very helpful and accurateLove this amazing app..Version: 1.4.4
Nice app but one suggestionHi I really like ur app, but I wonder could u add a new function "save to log" into the app, so that I don't have to take notes on what aperture and shutter speed I was using? Thanks a lot!.Version: 1.4.3
