SpeedSound - Voice Speedometer for Android

A free program for Android, by GDApps.

This app is a simple and intuitive speedometer that speaks to you and tells you how fast you are going. It uses audio to make the updates, so you don't need to look at the screen. You can just listen through your headphones or speaker.

It's great for people who want to keep track of their speed during activities such as downhill skateboarding, e-boards, horse riding, racehorses, and many other outdoor activities.

You can use it in the background and it won't drain your battery. Moreover, you can use it even while you are playing music.

This also helps you avoid going over speed limits. You can configure a maximum speed alarm and receive an alert when you exceed the limit.
