Kerb Driver

Version 2.0.0 · build of 25 September 2026 · 114 MB · Android 8.0 or later
Already running Kerb Driver (Staging)? This installs straight over it. If Android refuses, the build you have was signed differently and needs uninstalling first.

This is build de76b33b, runtime 353c72bcf478ba046525cec05a0b6fee0d112ca2.
Once it is installed, open the menu and choose About. If the runtime shown there does not match the one above, the app cannot receive our over-the-air updates, and it will keep showing an older version of the screens however many times we publish a fix. Reinstalling from this page is the cure. A date on its own cannot tell you that, because several builds can share one date and still differ underneath.

On the phone

Open d20w3egvcgpwk8.cloudfront.net/test.html directly on the Android device. The QR on the front page is deliberately not repeated here: it encodes the site root, which serves the production build, and scanning it would quietly get you the wrong app.

Installing

1. Open this page on the Android phone and tap Download.
2. Android will warn that the file can harm your device — that warning appears for any app not installed from the Play Store. Tap Download anyway.
3. Open the downloaded file. If prompted, allow your browser to install unknown apps, then go back and tap Install.
4. Open Kerb Driver (Staging) and create an account, or sign in if you already have one.
