MPH/KPH Speedometer

I used it on my boat To see how fast I was going, and it worked as long as I was going slow. But when I get on the throttle it loses signal and doesn’t work, the high-speed Signal doesn’t seem to catch up to my device . They need to do an upgrade, I see one hasn’t been done in over year

It did not track my speed limit.

Why does it only go to 120? I tried it on the bullet train in japan and it didn't work

Good APP

Confused

This app is very accurate. I had a truck where the speedometer was off and I use this to judge by how much. I was around 5 mph off due to tire size. I am so glad I found this app. Thank you! I use it everywhere now.

Use this a lot while fishing on the river!

I use it when I travel via Amtrak to get a sense of our speed. In many European trains a speedometer is present in each carriage, and this provides the same service here. It is nice to know you're blowing past traffic on I-95 at 120mph. My only request would to be able to optionally add KpH to an inner ring, as in automobiles.

App worked excellent!! Even under hard acceleration the needle was very accurate .. The digital speed on the SS Camaro matched perfect "154" sweet!

Worked perfect until the.update...now the needle just lays on zero.
