Getting Started

Location Permissions
While Using the App
Needed to show your position, record explored areas, and draw your recent track.
Always Allow
Needed only when auto-recording is on, so exploration and your recent path continue when the app is in the background or the screen is locked. You can turn auto-recording off at any time.
See our Privacy Policy for details.
FAQ
Why isn’t my map revealing as I walk?
- Check that location permission is granted.
- Turn on auto-recording (long-press the center button).
- For background use, set Location to Always in iOS Settings.
- Make sure you are outdoors or have a good GPS signal.
Why is there a gap in my recent track?
Gaps usually mean location was denied, auto-recording was off, or the app was force-quit. Enable Always location and keep auto-recording on while moving.
How do I change language?
Settings (gear) → Language → Follow System, English, or Simplified Chinese.
How do I hide the recent track?
Settings → turn off Show Recent Track. You can also change track color there.
How do I delete my data?
Remove TraceWorld from your iPhone. All exploration and track data stored by the app on that device will be deleted. There is no cloud backup from us.
Does the app work on iPad?
TraceWorld is designed for iPhone only.
