Android Auto / Apple CarPlay App Development – GPS Average

I am looking for an experienced mobile developer to build a simple but reliable vehicle speed monitoring application called "Average" .The app will work with Android Auto and Apple CarPlay and will calculate vehicle speed / average using GPS only (no OBD, Wi-Fi, or Bluetooth connection required).

"Average" is a lightweight driving companion app that displays:

- Current vehicle speed (via GPS)

- Average driving speed (calculated during the trip)

- Clean and minimal UI optimized for in-car display

- Android Auto compatibility

- Apple CarPlay compatibility

The app should operate using only location services and GPS speed data.
Please feel free text me I hope you discuss the timeline and budget. thanks
