GPS HUD is an Android app developed by INAPP that provides a GPS speedometer and various information receiver for cars, bikes, and bicycles. The app has a GPS HUD mode that flips the display to be mirrored on the windshield, making it easier for drivers to keep their eyes on the road while using the app.

In addition to displaying GPS speed, bearing, date, and time, GPS HUD also has the ability to auto-answer incoming phone calls with the speaker and show SMS text messages. The app also changes the color of the text based on GPS location and weather. Users can get titles from RSS and share RSS addresses with other users. The app also features an ECO drive indicator and GPS speed camera warning (in the pro version, speed camera data is not included).

The latest update to GPS HUD allows users to change the font size by% of the default size, making it useful for varied screen devices like 320x480 and so on. The information ticker is also able to be turned off, giving users more control over the display. GPS HUD Pro has been released, which has no ads and future upgrades.
