Allow Installation from Unknown Sources
When you try to install, Android will ask you to allow installation from unknown sources. This is required because the app is not from the Play Store.
Tap "Settings" when prompted, then enable "Allow from this source".

Install the App
Open the downloaded APK file and tap "Install". Once installed, tap "Open" to launch the app.

Grant Permissions
The app needs location permission to track your position. When prompted:
- Tap "Allow" for location access
- Select "Allow all the time" for background location (recommended)
- Allow notifications (optional but helpful)
7
Start Tracking
Tap the large "Start Tracking" button. The app will begin sending your position to the server every 10 seconds.
Testing Your Setup
Verify It's Working:
- Start tracking on your phone
- Open https://wstracker.org in a web browser
- You should see your position appear on the map within a few seconds
- The "ACK Rate" on your phone should show a percentage (ideally 80-100%)
During the Race
- Keep the app running - don't close it or the tracking will stop
- Lock screen is OK - the app continues tracking in the background
- Request Assistance - if you need help on the water, long-press the green "Request Assistance" button
- Battery - the app is designed to be efficient, but consider bringing a power bank for long races
Troubleshooting
ACK Rate shows 0%
This means the app cannot reach the server. Check:
- Server address is exactly
wstracker.org
- Port is
41234
- Password is correct
- You have mobile data or WiFi connection
Position not showing on map
Make sure:
- Location permission is set to "Allow all the time"
- GPS is enabled on your phone
- You're outdoors with a clear view of the sky
