Ratings and reviews

You're forced to make an account, seems unnecessary, but ok. This process is then made as difficult as possible by having the country of practice list in a completely random order. It's not sorted alphabetically, not even sorted by continent. Same with specialties, there's no order to it. App works fine, has an incredible amount of calculators. Specialty specific lists seems irrelevant, they're very extensive lists, but then YEARS isn't in EM for example.

Of late, the app, which was previously unparalleled, has become unusable. I'm lucky to get it to load, much less actually access the calculator I want. I've been let down on many a Ward Round of late: couldn't quote the patient's Creatinine clearance; had to leave calcium uncorrected, etc. Need this app to get back on its A game.

One of the most helpful toolboxes I carry. All of my calculators in one place. Essential for medical providers and students alike.
