Speedo is very close to accurate, but a couple seconds slow. Compass and accurate should not be used in the same sentence, though. Also, exceedingly heavy on battery drain.

Awesome app. My speedometer in my truck is off by 10 miles per hour. I use SpeedometeR to adjust my driving in all kinds of traffic and rely on it daily. Whenever and wherever I am driving SpeedometeR is on my dashboard. Love the way it changes colors judged on how fast your driving. Easy on the eye pick up immediately if exceeding certain limits.

I have tried and tried to find a good app to see the top speed of my fourwheeler. This is the first one that worked. I finally topped out at 56 mph! And to the dork who has a lambo, if you can afford a gallardo, you can afford to get a speedometer fixed. I prefer American muscle to Italian P. O. S. Any day of the week.

Been having some problems with the cluster in my dashboard and mice but amateur is not accurate. This has been my saving grace. I have found that it is spot on no matter what. Great job
