Good but could have more

It would be nice if the 4T score for HIT was added.

Shock Index and Nice APP

Nice APP would like to see shock index added to the formulas.

Emseducator72Version: 4.6
Good, with minor details though

As ICU fellow, one of the reasons for getting this app was the iv drip calculator. It works fine, but once you have entered and saved the doses & concentrations, there is no way to identify the drug while you are page plotting the numbers. There is option for "units" as in insulin & the letter in the notes are very small. And what happened to the PERC rule? this is another basic calculation.

Adan.atrihamVersion: 0
By far, the best

This app is must-have. It has every calculator I've needed on the wards, and it often surprises me with bonus information I didn't even expect to be included in the results. It's fast and reliable. I'm paranoid and like to check results by hand at least once, and I've yet to find any mistakes. MediMath is the only medical calculator to take full advantage of the iPhone rather than feeling like a port of an old Palm application. I recently took advantage of specials to try Mediquations and Medical Calculator as well, so that comparison isn't just a guess from screenshots. For example, while the other apps make you tap to different screens to enter the numerator and denominator on a fraction, MediMath presents it as a fraction on the main screen, where you can enter values and change the units. The only thing it was missing was a pediatric dosing calculator, which the author added for the next version (1.4) and even sent me a personal build in advance of its release when I emailed him asking for it and he had added it. You should get MediMath ASAP.

Best medical calculator out there

This is perhaps the best medical calculator currently within the App Store. Sure, it may be costly compared to others, but this calculator is the complete experience. I have tried using all the other medical calculators in the App Store and each one is missing a few key calculators/features. However, MediMath is the only one that has them all. As for product support, the developer is within the medical field, is very responsive to emails, and regularly puts out new updates. As an aside, be aware that MediMath contains tools that may be another apps only feature. For example, there is an app in the App Store currently that only calculates IV drug dosing - for $4.99. In addition to its many other calculators, MediMath also has a built-in IV drug dosing calculator.

The Best - well worth the price

I am an ED physician used to relying on my old palm for years for a number of calculations. The addition of the NIH stroke calculator as well as the numerous other applications makes this tool easily the best one available. The "favorites" feature is helpful to find those medical calculators relevant to my field in a timely fashion. I very quite familiar with other similar products on the market including the free application. The author - a medical student in Atlanta - is very open to quickly to adapt any reasonable suggestions for improvement in future editions. That alone is worth the modest price of admission. I highly recommend it.

Hfg1955Version: 0
THE BEST!!

This by far is the best med calc app available. It took leaps ahead with the addition of catagories. Aside from this addition it has the easiest interface & feels the most polished compared to the competition. The number of calcs in an app like this is nice, but the ease of use & thoughtful design makes this the standout clear choice. Everything to the smallest detail is user friendly and complete. Evan is actively improving this app, not just throwing more calcs in it for the numbers game. I'm confident more calcs will come, but this is the app in which they are the easiest to use. Great Job!

Helpful application & additional feature written by request!!!

I have now purchased both MediMath and Mediquations (both for the same amount) and found MediMath MUCH more helpful! I needed an additional feature to calculate pediatric BMIs so I e-mailed Evan and within a week this feature was available! It works perfectly- I could not be happier to have this application on my iPhone. It's easy to use, and will be with me through all of my clinical rotations. I strongly encourage anyone in the medical profession to purchase this app.!

Best Medical Calculator Program I've Used

I've been using Medimath for the last couple of weeks while on clinical rotation along with the free 'Medical Calculator' program. I've found this program to be more stable than 'Medical Calculator' in terms of not crashing, and is much easier to use in terms of entering in values (Cr levels, etc) quickly on the wards. There are lots of equations present with Medimath right now--far more than 'Medical Calculator--and far more ones that I find useful on a daily basis.

The best of the medical calculators!

This application is the cleanest, fastest, and easiest to use of the med calculators out there. As a practicing neurologist, I make use of it every day. When I suggested a change to the NIH stroke scale, the author wrote back immediately and had already made the changes! Though some of the other calculators have more equations, none are as easy to use nor change so quickly in response to user feedback to the author. Great job!

StrokedocVersion: 0
Excellent Program

I've tried a few of the medical calculators out there and medimath is the best. The interface is clean, the calculators have nice descriptions of the formulas and how to interpret them and the customer support is very responsive. The most recent version implemented a number of suggestions from other customers (fluid calculations, NIH stroke scale, apache II score) and I imagine it will only continue to improve. Pediatric formulas are also included.

One Out of One Doctors Surveyed Recommends MediMath

Well on its way to earning the coveted 5-star rating. Even Schoenberg cares enough about making this the best medical "calculator" that he returned my email within hours! I suggested adding the MMSE and the PHQ-9 and he is on it! Thanks for a great app and thanks for listening to what we need.

DanDiamondVersion: 0
Beautiful! A necessary daily resource.

I've tried the free option and Mediquations; I'm keeping MediMath. I love the attention to detail and smooth entry mechanism (a lot like Safari with previous/next buttons to go between items). It has all the tools I need on a daily basis. I've recommended it to my colleagues.

TalkTimeVersion: 0
Most comprehensive and easy to use of the medical calculator apps.

I have used all of the iPhone med calculators, ant this one is the most comprehensive. The documentation and discussion of each calculation is also superior (compare "anion gap"). Additionally the developer was very responsive and prompt in adding a request (Duke Treadmill Score). This is the one to get.

DrdecoVersion: 0
Great medical calculator! great support!

I was appreciative when this great medical calculator went on sale. I immediately emailed the developer with suggestions of essential calculations/references that I use on a daily basis as an FP. Now, with the update released today, they were all there! Can't beat that! Thank you, MediMath!

Great for anesthesia formulas

As a nurse anesthetist student, this app is great to plug in numbers for care plans. It has it's own "Anesthesia" tab with pertinent calcs. Can also reference actual formulas for deriving #s under "info" when need to refresh your memory for things like the alveolar gas equation, Henderson-hasselbach, etc. Great app so far!

ElizBetBooVersion: 4.3

Very helpful app

My one complaint regarding this app would be it would be SO helpful if there was a "clear" button so that you could clear the numbers that were previously put in.

Seventhheaven007Version: 4.3
Chose this over MedCalc

Researched medical calculator apps for a while, and had it narrowed down to this and MedCalc. I chose this one due to positive feedback about the developer's responsiveness to feedback/requests, and because the developer is a U.S.-based physician, while MedCalc is a Swiss app. Support the U.S. economy!

Great medical calc

Easy and quick to use. Unfortunately, it doesn’t seem to be getting any updates, and a couple calculators don’t work: the age calc won’t let you input a birth year, and the temp conversion calc only converts to C. There are other apps for that stuff, though, and important calculators I’ve tried all work.

MediMath Medical Calculator Negative Reviews and Ratings

Infusion calculator

Was an excellent app until one day the infusion calculator (IV RATE) was removed along with all my saved medications and notes. Just gone... So upset. Now it's just an app with a few useful calculators but it lost its edge it has over the others

Problems with certain apps

Despite paying for this app, all of a sudden it stopped working, when clickin on the app, it closes up. So very frustrating, dont know how to report get my money back. Not to mention cannot use it when needed. Bought a different app with similar features called mediquations, really like it.

Good app, very helpful in the clinical environment. I would like to see a quicker method to add favorites instead of having to go to my favorites to add the calculators used more often.

I have enjoyed using this fine set of calculators until now. The display no longer rotates the orientation, a nasty glitch. It will only operate in the portrait orientation, with the iPad button at the bottom. Please fix this.
