Check your current version
Android Settings > Apps > Batwin shows the installed version. The current release is 1.14 (3.28 MB). If you see an older number, update either way below.
Way 1: in-app update
The app can fetch its own updates (that is what the request-install-packages permission is for). When it offers one, accept and let it reinstall itself; your login survives.
Way 2: manual update with the APK
- Download the current Batwin APK in Chrome.
- Open the file and tap Install. Android treats it as an update because the package name (com.btwn.ybt) matches; do not uninstall first.
- Open the app. You stay signed in, wallet and history intact.
If the update will not install
- Free up space: you need the 3.28 MB file plus unpacking room, 50 MB free is comfortable.
- Download the file fresh; a partial file throws a parsing error.
- Make sure the old app came from the same source. A signature mismatch blocks updates; the fixes page covers it.
Update questions
Does Batwin update automatically like Play Store apps?
Not through the Play Store. The app prompts you in-app when a new build ships; accepting the prompt downloads and installs it. Nothing happens silently in the background.
Can I keep using an old version?
Old builds keep working until the server requires a newer minimum. When contests stop loading on an old build, a manual update with the current APK is the fix.
