How GPS mileage by state works, and why background tracking matters
2026-11-06 · Mile-Tax team
To split miles by state, an app records GPS points along your route and measures the distance between them, assigning each segment to the state it falls in. Where a segment crosses a border, a good app divides it at the line.
Why the screen-off case matters
Drivers do not keep the phone screen on for twelve hours. Web apps usually stop recording when the screen locks. A native Android app can run a foreground service with a visible notification and keep tracking.
What to check in any tracker
- It records with the screen off.
- It discards inaccurate fixes and ignores parked time.
- It shows gaps instead of hiding them.
- Your data stays under your control; see our privacy policy.
Mile-Tax is built around these points. Android comes first.
