Excellent
Not great
Results are not able to be seen after filling out the forms. I have tried different forms with the same result. Even while typing the review, I cannot see what I am typing. I
Update - Working Again!
Works well again. Thanks
Era bom…
Antes era muito bom, mas de um tempo pra cá, toda vez que volta pr menu inicial ou faz qualquer coisa, aparece “atualizando” e demora para voltar. Perde-se muito tempo. E é totalmente desnecessário! Não precisa ficar atualizando a cada poucos segundos!
Only one calc at a time
Great resource, but app freezes if you use the app for more than one calculator. Get out of the app between each calculation.
Great App
I very much enjoy this app One of my go tos on the job
Excellent until now
I have a long list of favorites. However, now, something is wrong, “bugs” the app freezes at the end of questions. It happens on all the decisions trees.
Love it so far
Loving it so far. I would like to request a drug compliance calculator. And maybe a research nurse specialty. We have to use whatever calculator our sponsor wants us to for our studies which makes this app super useful.
Fix this please!!!!!
Will not allow you to add anything to the favorite list.
Nueva actualización
Con la nueva actualización no se puede utilizar la aplicación sin internet, en mi pueblito de servicio social hay veces que no hay señal y mucho menos internet, por favor arreglen eso
Great App for students
Easy to use and comes in handy on rotations!
Bugs!
App freezes just when a questionnaire has been completed
Calculations
Looks interesting but need more time to evaluate.

Algunas escalas al usar la APP se cierra automáticamente.
It’s not working
With the recent updates the App is not working, is blocked and throws many mistakes.
Don't waste you're time
Absolutely worst support I have ever experienced. App will not update and most calls won't function. Emailed them and no one ever responded. Don't waste your time.
Scam
I have no recollection of signing up. But they are spamming my email. I tried downloading the app to delete the subscription and account since that’s the instructions I found online. However, I am unable to do either. I found a privacy email and it send me a message saying the person no longer worked for them. Absolutely ridiculous
Great app could be even greater if...
This could be a money maker for the developers if they gave the option for putting a name and date and top and then the ability to print so we can put it in EHR or even better integrate with the ehr and send the results to the ehr. Providers are now getting paid by insurance for administering scales but they must be documented in the chart. I would pay (to a. Retain price point of course) to see that happen. I recently emailed you saying something similar. I have notable experiences as a user interface tester for an ehr and can provide assistance if you need a consultant a few hours a month. -DanielleZ
Full of issues
This new version is just too full of glitches. All the time it refreshes, makes me enter data over and over again...
Opiate conversion
Good app. Would be a better app if it also had calculations like opiate equivalence- which seems to be missing.
Easy to navigate
I like it! If I would change one thing, I'd make it easier to clear current inputs and start over, especially for trending labs ovee Time.
Won’t work now
Used to love this app. Now I can’t open it. When I try and access it from Medscape the obstetrics calculator doesn’t work. It’s the only one I want. 😡
Variety of calculators available
Gives a variety of calculators available. Latest update added ads, but I'm actually able to use the app again.
Very disappointed with the new version
Less stable, large ad for their other app on top and worst of all, sponsored content.
Muito bom!
Muito útil! Excelente! iPhone 6
The best iPhone Med !
The best iPhone Med calc I have used so far, maybe just add a save function so you can look back at previous scores
Calculators not working, outdated resources
So far have tried about 5 calculators and they don’t work and when prompted to contact support and send the email that also doesn’t work. Specifically (so far) MGUS and CKD calculators not working. Also feels clunky. Really should have a units conversion calculator as well for metric to imperial weights and heights and temperatures.
Great app
Very useful
Ultima actualización
Baje la ultima actualización y dejo de funcionar, no abre la aplicación por favor arréglenla.
Won't work in iOS 8
Iphone 6 and this app will not open. Just shuts right away. Otherwise use to be a great app!
Good application
Practical supportive and gives u all needed tools for medical practice.
Still Annoying
Used to be a great app, but is constantly harassing you to make an account or sign on with Facebook. Should support sign on with Apple but doesn’t. This latest update still didn’t fix the problem. Hopefully Apple starts enforcing the rules soon. Kind of disappointing the devs are going to wait for Apple to force their hand rather than being respectful to users.
Good
Though I think that every doctor should not need an app to make decisions but this is very useful for renewing knowledge.
Não funciona direito mais
Desde a ultima atualização está com defeito e desligando sozinho
Bug ao ligar
Bug continua ao ligar!!!!!
Good
!
Crashes
Crashes constantly
So helpful and informative
I'm surprised how such an app can be free. It is absolutely incredible
Didn't work
Uh... Still crashing LOL
Bad actualization
Even with this last actualization the app has crashed yet...
Great app
Highly recommend it great interface provides references and ranges with links to original literature related to certain score.
Translate
Better if Spanish option
Good
Good
Sigue mal la app
A pesar de lo que la actualización promete, continúa cayéndose tan pronto se abre, quienes tengan este problema les recomiendo que desinstalen la app, desactiven actualización automática y por nada del mundo actualicen, quédense con la versión vieja!
Great!!
This application is really awesome!! You have to have it in your iphone :)
Great app design. Use it frequently.
Great app design. Use it frequently.
glitch: can't change settings
The app won't let me change the settings that it forced me to pick at the start. When I try to exit the settings menu after having changed them, the app asks me to "input a valid email". I've already given it my email and activated my account!
New update
Works well. 2013 AHA calculator is useful
Bugado
Ainda com bug!!!
Cardiac risk index
I can not find goldman's cardiac risk index for preoperative evaluation of patients undergoing non-cardiac surgery
