◆ Frequently Asked Questions (FAQ)
─────────────────────
Q. How does it measure speed?
A. It calculates your speed using your device's built-in GPS (satellite positioning) based on changes in your location over time. It works regardless of your mode of transport. However, accuracy may vary depending on your surroundings and GPS signal strength.

Q. Why does it show a small speed even when I am standing still?
A. Minor GPS signal noise can sometimes cause a tiny speed reading. Accuracy improves significantly when you are in an open, outdoor area.

Q. What do the GPS accuracy indicator colors mean?
A. Cyan: Highly accurate (under 10m) / Yellow: Moderate (10–30m) / Red: Poor (over 30m). Clear outdoor environments provide the best results.

Q. Does it track my speed in the background?
A. No. The app only tracks speed while it is actively displayed on your screen. Measurement stops automatically when the app goes into the background to save battery.
