Download TET Sadhana

The Google Play version is recommended once it is available — it updates itself and Play verifies the app's identity. Until then, you can install the APK directly.

How to install

Android blocks installs from outside Google Play by default. These steps enable it just for the app you choose to install from (Chrome, or your Files app), not permanently.

1. Tap Download APK above. Chrome downloads the file.
2. Open the downloaded file from Chrome's "Downloads" notification, or from your Files app.
3. Android shows: "For your security, your phone is not allowed to install unknown apps from this source." Tap Settings.
4. Turn on Allow from this source for Chrome (or your Files app), then go back.
5. Tap Install. If Google Play Protect shows a warning because the app isn't on Play yet, tap More details → Install anyway. TET Sadhana does not ask for risky permissions — Play Protect flags any app it hasn't scanned before, not a problem it found.
6. Open the app and sign in with your Google account.
