Android Phone or tablet

Certio is in Google's closed testing at the moment, so you install it directly from us rather than the Play Store.

Download Certio for Android
  1. Tap the button above. The file is around 110 MB, so use Wi-Fi if you can.
  2. Open the downloaded file — from the notification, or your Downloads folder.
  3. Android will ask whether to allow installs from your browser. Say yes, then tap Install.
  4. Open Certio and sign in with the same email and password you signed up with.

Chrome will warn you that this kind of file "can harm your device". That's the standard message Android shows for anything that didn't come from the Play Store — tap Download anyway. The app updates itself from then on, so this is a one-off.

iPhone Beta

Our App Store listing is with Apple for review. Until it's approved, iPhones get Certio through TestFlight — Apple's own beta app.

Join the Certio beta
  1. Install TestFlight from the App Store if you haven't got it — it's free, and made by Apple.
  2. Tap the button above, then Accept and Install in TestFlight.
  3. Open Certio and sign in with the same email and password you signed up with.

TestFlight is how Apple distributes apps before they reach the App Store. When our listing goes live you can move across to the normal App Store version.
