GTR


GTR measures acceleration times for 0-60 mph, quarter mile, 0-100 km/h and 0-400 m, acts as a speedometer and records top speed. The navigation feature guides you back to your car or hotel. GTR also shows basic GPS data.

GTR uses sensor fusion of your phone’s GPS and accelerometer for high accuracy results. It detects acceleration start and end automatically and stores results to files. Just start GTR and go!

GTR has three views, PERF, GOTO and DATA:

Slow Nice features only if it would keep up with my truck. 0-60 time is lagging I can't get an accurate reading. My truck is going 80 by the time this catches up and says I'm going 60. Its accurate if you are just cruzing but that's what they make speedos for. Want a refund

It works! It does just what it says. It's simple and doesn't require intrusive permissions. I don't believe perfect apps exist, otherwise I'd give it 5 stars.
