HOW SURE ARE WE
Small app: combines its grossing ranks with ratings growth (231 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.

★★★★★ This app is intentionally misleading in their ads inside other apps - it says iPhones can now take blood sugar readings, but DOES NOT say that this app doesn't support it.
★★★★★ Yet another app that screams free in the advertisements, and then wants a weekly fee in order to use it.
★★★★★ The advertisement is misleading and false.

★★★★★ This app is intentionally misleading in their ads inside other apps - it says iPhones can now take blood sugar readings, but DOES NOT say that this app doesn't support it.
★★★★★ False advertising. The only reason I downloaded this was to check blood sugar. The app looked for previously entered information or Bluetooth connection to a blood glucose monitor.

False advertising.

This ad is fake. It says completely free when it’s not free. I was going to use it until it lied to me.

False advertising in their ads!

This app is intentionally misleading in their ads inside other apps - it says iPhones can now take blood sugar readings, but DOES NOT say that this app doesn’t support it. All this app does is help you track.
