GPS Dash is the #1 digital speedometer app on iTunes, and it now comes with Apple Watch support. This app is designed to turn your iPhone into a trip computer that looks and feels like the OEM dashboard of your vehicle. It is the perfect app for those who want to record their travel data for all their vehicles in a single application. GPS Dash offers real-time measurements on the main screen, including current speed, trip distance, altitude, temperature, average speed, top speed, compass, and time.

In addition to the real-time measurements, GPS Dash offers many other features, including the ability to record travel distance, top speed, average speed, and average altitude for each vehicle. You can also visualize your records on a map, choose from 8 different color themes or create your own, set a speed limit alert, and switch to HUD mode to reflect on the windshield. GPS Dash offers optional GPS data measuring on the background and allows you to share your records on Facebook and Twitter.

Please note that continued use of GPS running in the background can dramatically decrease battery life.
