Hey AndroidPIT, I made an Android app that measures how much time, or how little time, you save by speeding in your car. Android 4.2+, it's free, and has no ads. It's my first Android app so check it out and leave me some feedback or feature requests for a future version! I can't post links yet so you'll need to change the URL below.
Play Store / APK / GitHub: jakehilborn (dot) github (dot) io/speedr
Or, search the Play Store for "Speedr - time saved speeding"
