Also great in the ER. ### 3/5 — Useful but needs update. Don’t buy if you have iPhone X *2018-01-01, version 5.0* Update to be compatible with iPhone X please. I hate that I paid money for this and the developers don’t have the decency to keep the app updated with the current operating system. ### 5/5 — An absolute must! *2016-02-06, version 4.0* Amazing app from both a design and content standpoint. Indispensible for junior residents starting off their nights on call. Tons of useful info packed into this app, very pragmatic. My only suggestion would be to revise the content and references to make sure all the information is still up to date seeing as many are from 2009 and before. ### 5/5 — Great app *2016-01-06, version 4.0* Love the new design. Content remains excellent! Thanks! ### 5/5 — Still awesome *2015-02-12, version 3.2* Love this app, needs a refresh but still a five star app for any intern who wants a quick reference for when the pager goes off ### 5/5 — Amazing app for a PGY1 *2014-09-12, version 3.2* Great app for residents .That would be great if more conditions could be added ! ### 5/5 — Fantastic! I use it every day! *2014-03-22, version 3.2* Fantastic app! I use it everyday. Gives exactly what we need in emerge, nothing that we don't. Everything is covered EXCEPT common disease and tx. Hoping to see this in the future. It's always nice to look up Tinea and see Clindamycin topical BID x 7 days ### 1/5 — Krayzee *2013-04-22, version 3.2* Not value for money, let down. ### 5/5 — FM Intern *2012-10-14, version 3.2* Great app. I use it all the time.
