Used to be good – Speedometer Speed Box Review

I used the free version for years because it was so accurate, then all of a sudden several mo tha back something went wrong and the speed fluctuates all over the place. I just mistakenly paid $4 thinking I had by mistake erased it from my phone and it wouldn't charge me to redownload but no...I just paid $4 for the non free version of the same app that STILL doesn't work. I'll be driving set on cruise control and it will vary by more than 10 mph over a few minutes. USELESS! Oh, and by the way, there is NO support. It's a dead link.
