Ratings and Reviews

Medical App developed by Physicians? Yes please!


I am currently a med student and find myself in situations where I need to rely on extremely fast recall. This app has been a life saved. Mostly because it was developed by actual physicians. It is rare to find an app that isn't solely concentrating on commercial profit. Thank you!

Waste of money

M3 student

I wouldn't waste your money on this. It is about the quality level of a free app. Very primitive in that it offers a ddx which most students or residents are already to come up with. Does have mnemonics but so does google. I was expecting something that maybe included tips to differ between things clinically or management tips/pearls/pimp related things.

Must have for residents and MS4s

Amit Badiye MD

Awesome app! If you wanna survive your residency ( specially those night calls when you are alone and your senior is not accessible !) this app comes very handy.
Running late for morning report and don't have time to prepare your case, this app is for your rescue!
Pre-rounding and want to suggest differentials this is your best friend.
Boards, humm who thinks bout boards during residency or atleast when u r a third year trying to apply, paying 1000s of $$$ for board reviews or using this time trusted friend , folks choice is yours!
Highly recommended!!
