Great App

I use this app to check speeds on my vehicles. It is great and accurate. I also use it when I check speeds on golf carts that are purchased at my business. I use it to check the speed of the carts when then come in to us and after I have installed the lift kits seats and larger tires. I also you the mileage feature while testing the carts!! Wonderful app!!!

So Far So Good!

I like how the speedometer looks! I paid the 1 time fee of like $1.99 bc if not it’s totally got a lot of ads.
I like how the regular speedometer looks! Best part about makin the purchase is it’s got several color to pick from.
Now the CONS:
1)yeah it’s got a lot of colors, but several look almost the same color as the other choices.
2) the HUD display! It don’t change colors. It stays plain white. It’s already almost a completely blank screen might as well at least let it match the color theme of the speedometer!
~ but I’m sure it’ll eventually have a update! It’s still totally worth the $1.99
