1/4 miles off but cruising speed dead on Don't be surprised when your ET is 2+ seconds off.... my car is well into the 13 seconds and that is not what the time was lol for what its worth its not too bad especially giving real time speedometer info. But after that accuracy goes to the wind that's pretty much the extent of the app. It needs more optimization/more per second snapshots at high acceleration to be accurate but overall pretty ok
Accurate within 0.1-0.2 seconds I road &drag race my modified 370Z race car. Its equipped with a Stillen Supercharger & plenty of other goodies. At our local drag strip my Z ran 10.09 at 132mph.I have another 370Z as my daily driver. The only mods it has is Nismo R-Tune, long tube style CAI's, Stillen 3 into 1 headers, CNT hi-flo cats, an Ark Grip cat-back exhaust,& last I had the ECU UpRev tuned. My daily driver runs low 12s.Ive compared track times to the app times,very close,within .1-.2 seconds.A nice device is helpful.
Speed run does not work for me The only thing this is useful for is the 0-100 speed test, but it doesn't get a gps fix despite 17 sats in reach. The normal speedometer works fine, only the timing one keeps telling me "you must be at a standstill" while I am (your speedometer even confirms it) alternating with "n sats in reach, 0 fixed".
Did work...barely now. I have enough intelligence to know that it's not going to be accurate (unlike others here), it's for comparing runs between mods and adjustments out with other cars. It worked on my Droid a few times but now barely works...I think it has issues working with the gps. Also says to standstill when I am. Fix these issues with the Droid and it'll be great.
Stupid I think the people who like this app drive slow cars and know it, but it says they're faster than are so they give it the thumbs up, the best 0-90mph run I've done was 7.34 sec. This app said my 0-20 was 8.54, and my 0-60 was also 8.54, on the same run, that's amazing huh? Gained 40 mph without a hundredth of a second passing. Wow
Works fine This app only works as good as the GPS on your device. I've gone through a lot of custom roms and have done a lot of testing with GPS and I know that getting good GPS reception is hit and miss especially with stock roms (I guarantee 90% of the commenters are running stock). This app works great, but most commenters don't know what they're doing
