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 suck.

 

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 sucked the power out of the phone's battery like crazy. Can't remember what one it is but it had analog 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 button, it locks down around the phone. I think it was around 20 bucks several years ago.
