Quick checklist
- Location Services ON
- Apex250 / ApexRecorder Location permission: Allow only while using the app
- Precise location ON (not Approximate)
- Battery usage: set to Unrestricted (or “Don’t optimise”)
- Disable Battery Saver / Power saving while racing
Tip: You can usually open the right screen quickly by long‑pressing the app icon → App info.
GPS / Location permission
Apex250 needs location permission to measure the out‑and‑back distance and detect the apex turn. Recommended: Allow only while using the app + Precise location.
Method 1: App info (fast)
- Find the Apex250 app icon
- Long‑press → App info (or the “i” icon)
- Tap Permissions
- Tap Location
- Select Allow only while using the app
Method 2: Settings menu
- Open Settings
- Tap Location
- Tap App location permissions
- Select Apex250
- Choose Allow only while using the app
Precise vs Approximate: On Android 12+, you can often toggle Precise location on the same screen as the permission.
Keep Precise enabled for best timing accuracy.
Battery: set to Unrestricted
Some phones aggressively pause apps in the background when the screen turns off or the phone is in a pocket. Setting battery usage to Unrestricted helps Apex250 keep recording.
Common path (Android 12/13/14)
- Open Settings
- Tap Apps → See all apps (if needed)
- Tap Apex250
- Tap Battery (or App battery usage)
- Select Unrestricted (or “Don’t optimise”)
Extra things to check
- Turn off Battery Saver / Power saving while racing
- If your phone has “Sleeping apps” / “Deep sleep”, make sure Apex250 is not listed there
- Allow Background activity / Background usage if you see that option
If you can’t find it: use Settings search for “Unrestricted”, “optimise”, or “battery usage”.
Troubleshooting
Runs not detected
- Make sure Location is ON and permission is granted
- Enable Precise location
- Go outdoors and wait a moment for a solid GNSS fix
- Avoid riding next to tall buildings/trees if possible
Tracking stops / pauses
- Set Battery to Unrestricted
- Disable Battery Saver / Power saving
- Keep the app open while riding (foreground)
Still stuck? Use the app’s debug overlay (long‑press the logo) and send the debug upload to the admin for diagnosis.
FAQ
Do I need “Allow all the time” location?
Usually not. Apex250 works best when the app is open and tracking (foreground). Start with “Allow only while using the app” + Precise location. If your phone stops tracking when the screen turns off, keep the app open and set Battery usage to Unrestricted.
What should I choose: Precise or Approximate location?
Choose Precise. Apex250 uses GNSS speed/distance to detect the 250m out‑and‑back and the apex turn. Approximate location can make runs invalid or inconsistent.
I can’t find the Battery setting on my phone — where is it?
Try Settings → Apps → Apex250 → Battery (or “App battery usage”). On some phones it’s under “Battery optimisation” or “Power management”. You can also search in Settings for “Unrestricted” or “optimise”.
