FAQ

Is Speedometer PRO free?

Yes. It is free to download on Google Play and the App Store. It shows ads and offers optional Premium features such as extra themes.

Does it work on iPhone?

Yes. The App Store version needs iOS 15.0 or later and was released on 20 October 2026.

Can it show speed in MPH and KM/H?

Yes. You can switch between MPH and KM/H in the app.

Does it warn me about speed limits?

No. The current listing does not include speed-limit alerts or speed cameras, so we do not claim them.

Does it need mobile data?

GPS speed comes from satellites, not mobile data. The map tab may need a connection to load map tiles.
