Technical What is the best Android GPS Speedometer App?

My 49 Buick speedo is way off. I want to find a GPS app for my android phone so I can figure out what the percentage from 20 to 70 mph it is off so I can get a different gear to drive it. So what app have you found that works the best and is fairly accurate?

 

I use "Thunder Speedometer"
No ads and seems accurate when I try it in a daily driver

 

I use digiHUD currently. Theres a ton of them out there and most don't*****.

 

I use digihud, but I have to go into settings and turn off all kinds of stuff that is not the speedometer, first.

And I have to make sure to kill the app after I'm done, so it doesn't eat the battery.

 

I've got one on my old phone that worked great but*****ed the power out of the phone's battery like crazy. Can't remember what one it is but it had*****og and or digital readout along with an odometer that would pick up and go again if you didn't reset it.

 

WAZE has it all ! great GPS, speedometer, road condition, hazards, speed traps, etc.

 

O'm a Waze app user too. Use it all the time, even when I know when I don't need directions, because it alerts you to road and traffic conditions and will get you around traffic jams ahead of you that you aren't aware of.

 

I use a simple one.
Gps Speedometer, version 1.3.2
Simple and accurate.
Yes it has adds, but it's free and easy to use.

 

I use GPS speedometer. Free, no ads, has odometer for trip and total and max speed. Works well, no power probs at all

 

That's weird, I don't have ads.

 

You don't need a GPS app just run the car on a measured mile, that will give you the percentage you need.

 

That's how I check my odometer. Once I get that right by changing the gears in the transmission, then I worry about the speedometer.

what android app has speed in tenths?
I use DigiHUD , but I'd like one that shows tenth of a MPH for o/t use

 

One thing I found that eat battery power when using a speedo app is WIFI. Shut it off so your phone isn't searching for wifi and the battery will last a lot longer.

 

I tried 3 different ones, the digihud seemed to have the biggest digital readout/easiest to read of the speed which is what I wanted. Thanks to all that posted, Brian.

 

Not an app for a speedo but thought I'd share this. Needed to check my speedometer accuracy after some rear end work. Had a cell phone holder made for golf carts and with not wanting to look down at the seat constantly combined with the new cell phone laws in the state.....gave it a try. Worked like a charm. So if you're checking your speedo, or it's on the fritz, or you don't have one.....or a tac, if you use mapping on trips - this works. It's adjustable/magnetic (rare earth) and made for the cart cage tubing, so sticks like a big dog and non marring. Has never come off on the golf course and when I used it to check the speedo, went over some rough as hell RR tracks several times....never moved. Adjustable fit - squeeze the adjustment arms to open it up and when your phone hits the red*****on, it locks down around the phone. I think it was around 20 bucks several years ago.
