I have been using since graduate school and love having easy access to up to date, evidenced-based information.
Great info at your fingertips!
Excellent Quick reference. Easy to use.
Use it every shift Even as a staff ER doc I use this all the time. This and UpToDate is really all you need.
The best by far.
Poor app layout... Good content
Added CME support
Most comprehensive drug information with built in drug dosing calculators.
