HOW SURE ARE WE
Small app: combines its grossing ranks with ratings growth (0.8 new ratings a month on average since launch). Tested on 418 apps with verified revenue: typically off by about 2.6 times, so the range is wide. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

Bugs, things not working24%

4 of the 1 and 2 star reviews.

★★★★★ 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…
★★★★★ I just keep getting an error message saying to repurchase the app agsin rather than just restoring the app under the money already collected.

Latest reviews, United States App Store.

★★★★★Mar 6, 2026
Needs better update

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.

★★★★★Feb 3, 2025
Needs daily max dosages

Good app, but lacks some clarifying information like daily max dosages and pregnancy ratings.

★★★★★Jan 17, 2025
4yrs no updates with annual fee?

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.

★★★★★Jan 14, 2025
Why is there a fee with no updates?

The app is useful, but why is there an annual fee even though there have been no recent updates?

★★★★★Jul 12, 2024
Poor for updates

No new updates and the antibiogram is terrible on iPhone if and when it works

★★★★★Nov 6, 2023
Cefuroxime axetil is discontinued

Cefuroxime axetil is discontinued in us but still listed as tx for abscess
