Speedometer + HUD (Digital Speedo + Heads-Up-Display)

I tried some others and while most of them worked this seems to be the best! You must "allow" location services. It connects to GPS satellites. You pick MPH or KPH. You put it on your dash and it gives you giant speed reading or you turn it upside down and i tsreversed and you lay it on your dashboard and it reflects off the windshield in proper Jetfighter fashion. but reflected off the windshield it cannot be seen in daylight hours. With one click you can turn on an alarm that will notify you if you're going over a certain speed that you set. Every car should come equipped with this and until that day use this app! But lay a little piece of rubber or something on your dashboard, by your front windshield, because your phone will slide as you make a turn.

I love this app. My speedometer does not work on my car so this app is a lifesaver. Not only is it free but it is actually accurate.

I got the app, opened it and decided to check it out and i went into settings and went back out... And it was like backwards ???

I noticed this app asked if I would allow this app to access GPS/location if not running / background. Not sure why... Other similar app would access GPS/location only in use... Lets update your program as intent.
