The most recent update messed up the font sizing and format. Now it’s very awkward font size and difficult to read. Please fix this and update the anti-biotic guide.

★★★★★ No longer working after installing most recent iOS update.
★★★★★ App menus are slow, jerky and at time unresponsive. Unable to zoom in on reference tables or place phone in horizontal position to improve readability. IMO, it's best to get a hard copy to keep at your desk and pass…

Good app, but lacks some clarifying information like daily max dosages and pregnancy ratings.
No update in 4 years and they still collect an anual fee! At this point I’m sure they are thinking why even bother if people keep paying. Pretty scummy to be honest.
The app is useful, but why is there an annual fee even though there have been no recent updates?
No new updates and the antibiogram is terrible on iPhone if and when it works
Cefuroxime axetil is discontinued in us but still listed as tx for abscess
