Love this app but missing radicalLove the app but with you please make the Leupold VX-6 4-24x52mm radical?.Babble55Version: 3.75

Great ballistics program and a responsive software developerLove the app and use it all the time for hunting. Simple and accurate with lots of features to customize ammunition, targets, and compensates for differing environmental conditions from zeroing conditions. The developer is very responsive to my requests for adding new reticles. I don’t know how well this will work for super long range bench rest shooters but it is a great tool for all of your practical hunting and sighting needs..Bikerbob52Version: 3.65

Lots of potentialThe architecture of this app is great. However, I compared results of various load and calibers to some name brand site calculators. When it came to a .223 Federal Fusion 62 gr., it failed to calculate properly. I compared it to Federal and Winchester calculators and it was wrong. Federal and Winchester was almost identical. Anyone would love a cartridge like this app shows. I email the developer more than once and sent him the data. He said he found no problem..Hawgwild23Version: 3.60

I like this programThis go-to ballistics app. You can have lots of different loads for each rifle (or different pellets for airguns) and switch between them easily. The calculations are spot-on. My favorite feature is the ability to add your scope and reticle and have the app show exactly where to hold for your target..Tangle EyeVersion: 4.08

Great program great supportThis program works great and is still being updated regularly. If you have issues you get support. Highly recommend purchasing the “pro” or upgrade..DarqhelmetVersion: 4.53

Two thumbs upExcellent ballistic program. A vast array of ammunition and scopes plus all the details like altitude, temp and pressure effects (both when zero was established and at the time of the shot). Very accurate, providing both ballistic table as well as visual reference of the actual reticle of most scopes. Simply the best..Zombievil fanVersion: 3.78

Night boy to show more scopes update update they have shown as possibleCould you update this Avenue because it has not had some of my scopes in it for example diamondback 4-12x40 vortex very-1 mow Thank you hope you can correct this.305tanoVersion: 4.23

Great Shooting App!This app is really handy to have! Stores all my rifles with all their corresponding loads. You can see your holdovers on your scope reticle right in the app, print off your ballistic drop chart for your rifle/load. Very easy to use and very handy to have..WiHunterGuyVersion: 3.75

Quality ballistic appAbsolutely blown away by the quality of this app. I was immediately shooting targets at 700 yards. Started at 100 and within minutes was all the way out..Fiddlin FoolVersion: 4.34

Very Helpful AppI would recommend this app for anyone starting to shoot long range and learning their scope reticle a bit more. I was telling my friend about this app but I do not see his scope in the list (Firefield 8-32x50) Would it be possible to add it??.Yamaha50thVersion: 3.57

Great Ballistic CalculatorI use it all the time for long-distance shooting events and hunting. Most notable is the trajectory calibration and the different scope reticle you can select..SkibrianVersion: 3.71

Nice productIt amazes me every time I need to calculate elevation. Just so easy. I recommend this whole heartedly..StgeckoVersion: 4.38

Adding or changing infoHow do I go about getting you the info to add to the list of scopes you have the one I need but it’s a Nikko 4-16x44 Diamond skeleton reticle.Pussy28Version: 4.21

Outstanding product!Great single source to input all data on ballistics and get fast calculations for adjustments. Couldn’t be happier with this..Bremer County IowaVersion: 4.12

Love the appI find this app to be very helpful while I am shooting out to 500 yards. Love it..Hlcclh1Version: 4.43

Great app very helpfulI shoot NRL22 and this app is very helpful to calculate the variety of holds for the ammo used and target layouts in this competition..Uessless-94Version: 4.34

Great appLots of reticles and accurate ballistics. I wouldn’t mind seeing an impact29 reticle from leupolds vx5 riflescope though.Colohunter9Version: 3.66

Excellent ballistics programEasy to use, complex calculator. Nice backup features..GeckopelliVersion: 3.87

Absolutely necessary for Precision Rifle ShootersAs a PRS shooter this app is phenomenal. I have used this app in several long range matches at various ranges across America. If you have a precision long gun, you need this app. Don’t forget to change your weather!!! SGT_G.N.gardnerVersion: 3.56

Ok I guessWould be nice to delete old profiles Truing function doesn’t work well for 22lr beyond 100 yards.Tower CowboyVersion: 4.10

Great tool!I had downloaded this many versions ago, but for whatever reason never got around to using it at the range. After visiting an out of state range with different target placements than I had known dope for, I decided to give this a try. Worked well (my reticle isn't featured) using the dope supplied by the program. I'll be emailing the developer about getting my reticle added for the purposes of visualizing holdover as opposed to dialing in dope; but it got me on target dialing, do it did its job..BubbasaurusrexVersion: 1.54

Dig itWorks great with all of my rifles..XjxjebebeiiVersion: 4.23

Great app...Can y’all add my Schmidt & Bender PMII 5x25x56 To The app?.NykolasGriffithVersion: 3.82

I love itI have used it many times easy to set up as well. One day at the range the guys gun next to me went down and some one gave him a loaner we guessed on on a few of the items using what we knew about the bullets and scope setup. And he was hitting steel at 1,100 yards with this tool and I was using on my gun with all the right data punched in. It worked so good. I even scored a first round hit at 800 plus yards with I gun and scope I only put 10 round through before. I love this app it is also fun to mess with the Data and see what it would take to make ridiculous long shoots..Matthew LiebeVersion: 1.88

Awesome!I am relatively new to longer distance shooting. I used this app today with my new .223. After sighting in I was able to hit a milk jug at 450 yds first try. One thing I would like to see added is the ability to input the number of clicks adjusted from zero and still get a holdover reticle picture. For those of us using rather inexpensive optics and trying to shoot way out there it would be nice to tell the program that I adjusted 12 moa and have it still give me a holdover to shoot farther. Just a thought. Great app!!.Jillers32Version: 2.59

Worth the $5. Really like itThis is really great for a normal shooter. The ability to get info in clicks or in reticle holdover is great. Some reviews say this is a free app but I paid $5. Totally worth it. There is a pro version as well but that does not have the reticle holdover graphics. stelok has every reticle I would need Maybe if you are shooting .338 Lapua @ 900 yards with custom hand loads you need the pro version or another product, but then you are a pro and probably have a dedicated calculator. This is for the other 99% of us..BtdmanVersion: 1.80

Best Ballistic Software Available!Unless you want to spend $250. on Horus Vision's AtragMx software, this is the best Ballistic Calculator that is available! The creator of this application creates updates on an almost daily basis and continually adds new reticles as they become available. The creator has added numerous Horus Vision reticles upon my request and let me tell you, they are perfect! I highly recommend this ballistic software over any other, period! Nick Smith.South LA CopperVersion: 1.91

Very accurate!Thank you for adding the zoom feature! This makes a tremendous difference with the scope you are using. As long as you know your bullet specifications and sight it in properly, the program gets you there every time! I used to rely solely on yardage charts, now I mix it up with magnification adjustments and MOA. This program will help make you a better shooter, but you still need to know how to shoot!.AbacacacaVersion: 2.59

Some SuggestionsLooks like a great app, but I have not gotten to the field to test the accuracy yet. From my initial contact with it, I do have some suggestions. Most shooters on this side of the pond use imperial units. It would be greatly appreciated if you could specify Yards, Degrees Farenheit, Inches of Hg, etc. Having to run conversions on the fly will turn off many shooters. Also the "click" value needs to be user selected. Not all scopes adjust in 1/4 MOA clicks. Mine adjust in 0.1 Mil clicks and many scopes adjust in 0.125, 0.5 or 1.0 MOA clicks..LoneWolfUSMCVersion: 0

Accurate!I've been playing with this for a year. I finally shot my hand loads through a chronograph and entered the data into iStrelok. Using iStrelok for a 200yd target, my group hit 1/4" above point of aim. The free version is a must for any hunter who would have to shoot over 200yds and just plain fun for those who don't. I would like to see a deer/elk/moose hunting plex. An average deer's chest is 16 inches from brisket to spine therefore make the duplex for a "Deerplex" 16 MOA..OneTimeCommentVersion: 1.79

Fantastic and accurate ballistic app.I love this app! I use it in 3 gun at long-ranged to get an idea of where my hold over will be before I shoot the stage. It has never failed me. I am consistently able to engage targets past 300 yards quickly and accurately because of this app. I love that this app comes with so many different reticles! Definitely one of its coolest features besides of all of the physics and math and coding!!!.XBreezy2011xVersion: 2.90

Updates frequently!New sights are added every month or so. Love this app. The only bug I've found is that when I select a data field to modify that is below where my keyboard pops up - I'm unable to scroll the screen up. So I end up entering data "blindly" and hope its right. Specifically: the bullet weight or percentage values. Using an iPhone 4s..Neo2tthVersion: 1.58

Perfect!**UPDATE** The app is fixed now. The dev fixed the problem very quick. This is a really good balistics app. OLD REVIEW The last update broke the app, now it won't start on my iPhone. Until then it was a very quick and simple to use ballistics app. I used it more than the paid apps I have that do more. I'll change my review if it ever gets fixed..HiTekRedneckVersion: 0

Very accurateDont know why this has only 3 stars??? I guess some people are idiots. Spend a few minutes learning how to use. Amazing- no carrying around little notes about different loads and bullet drops. Also has many different scopes to show where your bullet hits with different reticules. I have several types with ballistic reticules. So really convenient. Thanks!.Eyeguy1243Version: 1.62

Ballistics made easyThis is by far one of the most technical yet easy to use ballistic shooting applications on the market. From the first time shooter to the long range professional, shooters of all skill level will appreciate this app. You would have to shoot thousands of rounds of ammo to gain the knowledge that this app unlocks. Get it and start shooting better today..DiscoStuTXVersion: 3.26

KRThis app is great. Have it on my droid too. Comparing this to some of the bullet makers calculators, results are right on. I like this mobile version cuz I can make changes in the field and always have a reference recticle on where my aim should be as well as corrections on the turrets. Will definitely recommend this to both avid and beginner shooters alike. Takes all the guesswork out the way..BigDaddy6959Version: 1.50

Great app!This is a great ballistics app for the savvy shooter. I've been using it for years and it has proved to be very consistent and accurate. I love that all of the reticles are added from several different manufacturers. I had a scope that wasn't listed and sent an email to the developer and within a week he had sent an update including my request..BrwndoggVersion: 2.93

GlitchStart off by saying great APP. I have found a glitch in the program. With a 25-06 reduced load 100 grain bullet 2550 muzzle velocity. I started to sight in at 25 yards and at 100 yards the program was 3" off. Other than this I have no complaints about the program. I use it on several different rifles and calibers and get great use out of it. Would recommend this to a friend..Amdrewquinn308Version: 2.19

Great appUpdate: 5/5 Now that the table has been added and the new reticles it's just about perfect!! 6/5 if G7 is added😊 Gave it 4, would have been 5 if you add another page where it shows a table /graph for range cards that is user adjustable down to 10 yards or meters. Any chance you would add the dragnov reticle?.CD0311Version: 1.60

New FeatureIStrelok is still my go to app for target shooting and calculations. The new feature to use the camera to measure slope is very cool. It seems close enough to accurate to me. Better then my eye balling and sighting in a slope. The feature is off by default and you have to click on the "i" to access the slider to enable. Then tap on slope input..I5xswipeVersion: 2.48

AwesomeThis app has evolved into an essential tool when precision shooting. It has majority of needed features of far more expensive ballistics apps but without the extra fuss or charge. It has the ability to import rifles to other devices and all ballistic info. Contains most popular reticles and the developer is constantly updating Overall GREAT app !!!!!.Blow Me !!!Version: 2.21

ThanksGreat app. Thank you Dev for offering it up for free. Also thank you for the email feature. If you ever want to add to it you could consider adding cartridge info - heck I'd have paid for the lake city m855 ballistics when I needed them. Maybe offer popular cartridge data as in app purchases? Just a suggestion. Either way, thanks..MvasilakisVersion: 1.73

Must have for long range pellet rifle shootingI've had his app for over a year now and I must say, with this app I can hit 2inch targets at well over 100yrds with ease... Gives you exact position on what mil to hold....they are also constantly updating the app with new radicals so your sight/scope will always be in the inventory to select..UrgirlinmyjettaVersion: 3.00

AwesomeThis is a great app. I have Horus retical scopes and have been using the Horus Atrag software and a Horus kestrel. This app takes the place of those two items. It's on my phone and iPad and works flawlessly. It's very fast to get your hold and make the shot. You can even use your camera on your device for slope indicator. Great app, thanks..IyaucyasVersion: 2.88

Best of the BestHaving multiple rifles and scopes, this product makes it easy to set up my rifles for competition. It is also excellent for backtracking to fine tune my exact bullet speed after getting a good approximation using various chronographs that I have and then actually measuring the true bullet drop on the target..Data doctorVersion: 2.73

ExcellentExcellent app just wish they had scorpion optics reticles.SlomaroVersion: 4.18

Must have!Super simple app, only regret is that I would like certain units in imperial, and certain units in metric. Why? Because I am Canadian. Range in meters or yards make sense, temperature in Celsius makes sense. Wind speed in meters per second makes no sense what so ever. Other than that it is my Goto calculator. God bless the queen!.SdwattVersion: 1.36

Bravo!Téléchargé samedi, utilisé dimanche au stand de tir. Très utile et efficace. Mais une version en français serait appréciée!.YvesboiesVersion: 2.54

Duplicate reviewNeeds upgrade option to pro..Mxpwr001Version: 3.17

So far, very niceTrying to find a reticle to match my Bushnell Legend 5-15x40 MOA dots (older scope, not the elite).17767Version: 2.82

Very easyVery easy and spot on.Holly Hip HopVersion: 2.02

Killer CalcHats off to you Igor! Thank you so much for this extremely powerful app. I especially like being able to easily store my rifles and the cartridges I use with them. I can instantly view my own reticle at any power setting overlayed over any target size at any range and get accurate drop details? What? That is simply amazing. I like to dial elevation and hold wind so this feature is simply outstanding..TalkynVersion: 1.98

Love this App :)This little tool is great! New reticles are added ALL the time, and there's a lot of configuration options ( Metric ?! ).I Know CodeFuVersion: 1.79

Good enough for me!Took my 308 out to 1000 yards in 18 mph full value wind with this program. Got me on target no problem. Accurate data on 175 SMKs. Good job! Too bad my phone is hard to see in full sunshine!.Joe btfsplksVersion: 1.69

Awesome boom pow toolThis is awesome.BlegendVersion: 1.53

Great free appI've been using this app for my Stag 20" target AR-15 and Norinco M14. Super accurate for adjustments. It's dead on for the 168gr sierra match king. Though I would not trust the sight hold over given in the app. Different scope and different size. Makes a huge difference on the hold over. Over all super app for free. If the developer could fix the "Mark" hold over with variable power it'd be amazing..C9-GunVersion: 0

Great application!Nice clean program that works well..C6699Version: 0

IStrelok Negative Reviews

Ballistic AE betterThis is an ok app, and it does work as advertised. That said, I’ve contacted Igor several times to inquire about giving the user the option to choose what outputs the user wants to see. I personally use MRAD only, and do not want to see the values for MOA or clicks - this just clutters up things showing useless data. Also leaves room for mistakes. For a couple of years I’ve been told that he would look into it and update the app - this is just lip service. Ballistic AE is a better app and only outputs the data you want..ShytbyrdVersion: 3.58

Good but go proThis is a good app but my data is off for two of my rifles. Collected all the data I could and triple checked everything but the app didn’t match what I needed on my rifle to hit. My friend had the pro version with the G7 bullet ballistics. He plugged in the same data and the pro gave him what I had dialed in my rifle..Dung refugeVersion: 3.69

Latest version crashesI’ve been very happy with the app up until this newest update. Everything seems to work except when I try look at the reticle and then it crashes..ChsandersVersion: 3.52

User friendly ?Recording information OK. Retrieving variation changes due to conditions, way to long to calculate for a long distance shots in hunting conditions! Fine for target. I love shooting my rifle but also use it to hunt! DON’T WAISTE YOHR MONEY IF YOU HUNT FOR INFORMATION ON THE FLY!.BajnoktwoVersion: 3.90

They don’t have my scope in their optionsI’ve got a viper HS LR 6-24x50 and They don’t have my scope in their list. Waste of money.WyoewVersion: 4.34
