Speed Alert Pro v1.9


Spoiler: Description
Requirements: 4.0.3 and up
Overview: Speed Alert is an assistive app for driver. It let you know when your car is traveling over the set speed limit by giving audibles alerts.

The app uses the analog form of the speedometer and the RPM meter that gives the audible alert when the set limit of speed is exceeded.

This app calculates car speed in two ways:
1) Use Bluetooth OBD-II adapter connected to car data link port to read car speed. The app reads the speed directly from your car's system via OBD-II Bluetooth connection, so the speed is highly accurate.

2) Use the built-in GPS capability on the phone and independent of the car. The app alerts you with calculated speed based on GPS data, (so it might introduce some delays compared with the Bluetooth OBD-II method , even incorrect data in bad weather)

Using the OBD-II adapter also let you to familiar with the car data link port, from which you can also read many other data with other apps that based on OBD-II standard.
