What's new in v3.1.1
Version 3.1.1 brings the app up to speed for the latest Android releases and has a lot of internal changes and fixes to hopefully make things better than ever. Most of our users are on Android 14 right now and everyone in general should hopefully have a stable experience. Apologies for the broken Google Fit integration, that is still not fixed, trying to resolve this by the next one.
Have awesome workouts, More soon.

How to install Tabata Timer and HIIT Timer v3.1.1 on Android 9 Pie+
Takes about 2 minutes. You'll need roughly 16.9 MB of free storage.
- Grab com.parabolicriver.tsp_56.apk — hit the Download button above (16.9 MB). If your browser warns about APK files, choose Keep or Download anyway — that warning fires on every APK, not just this one.
- Trust your browser to install — on Android 8+ go to Settings → Apps → Special access → Install unknown apps, pick the app you downloaded with (Chrome, Firefox, Files, etc.), and flip Allow from this source. On older Android, toggle Unknown sources under Security.
- (Optional) Verify the file — compute the MD5 of the downloaded APK and make sure it matches 4ddc0796a878ab9b…. Any difference means the file is corrupted or tampered — delete and re-download.
- Open the APK — tap the download notification, or find com.parabolicriver.tsp_56.apk in your Files app under Downloads, then tap it. Android's package installer will appear.
- Check the signer — the install screen will name the publisher. For this build it should read CN=parabolicriver.com, L=NewDelhi. If it doesn't match, cancel — you have the wrong file.
- Review permissions & tap Install — scroll the permission list, then confirm. If Play Protect flags it, tap Install anyway (this APK was scanned as TRUSTED).
- Done — open Tabata Timer and HIIT Timer — tap Open on the install screen, or find the Tabata Timer and HIIT Timer icon in your app drawer.
