About this app

GPS speedometer application, which uses your location data to display your current speed, and your maximum speed you have reached.

You can set the unit of the speed to km/h, mph, knot, m/s or to ft/s.

You can also see your distance travelled (in m, km or mi) and the GPS signal accuracy (in m, ft or yd) on the bottom of the application.

Very intrusive ads. In a speedometer app. The banner ad at the bottom of the speedometer is something I can live with. But the only thing I got from updating this app for "minor improvements" was more ads that cover up the whole screen. Mobile ads are the worst and this app added them to their speedometer app. It is 15$ A WEEK to remove them. Besides that it functions great for measuring speed accurately. No, I'm not spending 15 dollars. Thanks for suggesting!

We have a free and a paid version of the App. Our Premium (paid) version opens up more opportunities. You can try it out during the free trial. You may also wish to choose the free version with fewer features available. But we are sure you will enjoy the Premium version, it is definitely worth the money!

When this app works, it is great, but you tried to log in and it goes to some game advertisement and you can't get off of it.The ads I don't mind. ($ you pay free app.) What bad is certain game ads most time will keep on, and not time out so you can return to the speedo app. Won't even let you return to previous screen. Either have to exit completely out, or it gives 3 little arrows like this, >>>GooglePlay. That is bad, and dangerous if your driving, or boating. Fix that, and 4+ stars.

I tried three apps before trying yours. they wanted a lot of my personal information. and couldn't pick up my location on their GPS system. your app picked right up and showed my exact speed limit.. I love it.
