Drag Racer - car performance 0-60 mph 1/4 mile GPS
Acceleration drawn on a nice graph, analyze it, improve your driving skills.
With our star rating, you will know how accurate was your race.
Night racer? Check out "Head-up display" mode - place the device under the windshield and observe the reflection.
Save the race and load it anytime you want.
Important note:
- slow runs are ignored (below 25mph)
- best score isn't always the best (accuracy is important as well)
- measurement accuracy strongly relies on your gps device

This app is really great. It automatically restarts a race without touching your phone. Clearly shows 0-20 0-50 0-80 0-100 0-120, quarter miles and much more. Saving a race is one touch. Graphs are very helpful. Notification tones are also useful. The sound is a bit high pitched and very loud, maybe I could have adjusted the volume, bit I was having so much fun with the app I didn't really care. The mirror image HUD was a great surprise too.
Again, deleting reviews? I get it, your app is trash. Yet another untrustworthy app that cover up issues/bugs. #1 issue is the GPS, it will not stay at 100% signal unless moving. Once you stop, it loose GPS signal and then tries a recalibration but always fails after it hits 80% to 100% and then back to 0%. So its useless.
Looks like a great app but has a major flaw with Pixel phones. When moving, finds satellites and shows speed, but as soon as I somehow it resets, looses all satellite communication, hence I cannot time anything, pity..
Not 100% true results - I believe with about 1 sec delay to real d/t how GPS system updates. Example. During acceleration when car speedometer is on 120kmh already and I stopped accelerating, the app shows 90-95kmh and catches 120kmh only in about sec or so. After that - both readings same. However, the app is very stable and all the results are close to each other. This gives nice opportunity to check your car before and after chiptuning. The app stores the results and can overlay them on graph
Terrible app. Has trouble staying connected to GPS. Would never give 0-60 times, despite reaching speeds well over 100mph. Never have any other info either, except top speed and distance driven.
The app works well, I have compared it with a stop watch as well and it seems quite accurate. Can't really fault the app, it all depends on your phone and how good your GPS signal is. Just make sure your GPS signal is in the high 90s percentage wise and you will get quite accurate results.
It looks great and is easy to use but the accuracy is terrible. I did several 0-60 runs and it would never keep up, even with a good GPS signal. Each time I hit 60mph it was still showing between 20-30mph, and there wasn't any wheel spin to account for that large of a difference.
Can't keep a GPS signal. Every time I start moving it drops out only to regain it in a few seconds but what's the point then? You need to stop to get it reset, but then GPS is lost again. Useless.
This app is perfect for me because Im on a motorcycle. Its all automatic, all ya need to do after set up is come to a stop.. Its ready at every stop, all day, every day. No buttons to push, fully automatic, and records every run for later review... The best drag race app yet. Thanks for your work putting this app together. Outstanding!
Works ok.. GPS has issues.. a little delayed but helps if your tuning and need a BALLPARK TIME. is pretty consistent. But does not start until you're already moving.
Its really cool. It works every time for me. I run a homemade cart and it does a real consistent time. It does 8th Mile in mid-10. I wish you could lay the graphs of other races over each other. That would be really cool. I find it to be really pretty accurate and fun to use.
The app itself is awesome. The problem is, it won't keep a GPS signal long enough to record the times. I have 2 other "speedometers" on my phone, and they have zero problem with getting, and keeping the GPS signal. Really wish they would fix this, i really like the app.
Best app I have tried for GPS only times. Times seem consistant within the app and comparing it with others. The best feature is the auto start and stop for runs! It would be nice to be able to export the data. Great app!
Nice and simple to use but absolutely not reliable in my case. Half of my measurements have negative time-stamps or are simply missing (only max speed, the rest is gone) even though GPS signal quality is always perfect. App-restart doesn't solve the issue. I will up-rate on bug fix, if it happens...
Very disappointed, constantly searching for GPS until I start moving and then miraculously my GPS is found when I start moving again. Garbage. Gave it one start because it got my hopes up in the reviews and the first try of it. But so far every other time I tried the GPS can't connect. Uninstalling.. Looks like I'll have to pay to get any real accuracy like the forums talked about.
Used for the 1st time for 5 runs. Seems to be reasonably accurate and easy to use. I need a little more seat time to understand how the auto save works versus manual save. Also still need to learn what each of the tone are for.
It is free so cannot be to picky, but it always loses GPS during a run or freezes and always end up with a time that is 1-2 seconds slow on a 0-60 run. I can only imagine how off it would be at the quarter, but no room for that safely where I live.
It's a novity app...highly inconsistent and unreliable. I repeatedly tried in a 2017 Audi R8 Plus...best it recorded was a 8.7 second 0-60 and that was only 3 of 10 attempts. The other 7 attempts "lost" GPS signal. Lol.
Seems very accurate! I used it for a before and after, when I installed a cold air induction system. Showed a consistent difference between the two. Half second 0 to 60 improvement!
The interface is good enough especially the graphs, the autosave feature is great too. What I didn't like is the GPS signal not consistent. The app shows 100kph and my instrument cluster shows 112kph. This difference is huge meaning the time I get are not accurate. Work on GPS accuracy and I will give you 5 stars. Google map speed deviates with about 2kph so it is so close one can rely on it.
can we get an option to not automatically stop timing if theres a pause in acceleration, i.e. changing gear? Tried about five pulls before giving up on it, not about bashing between gears, and it keeps stopping timing on the 1-2 shift.
It will not connect to gps satellites for more than a few seconds. It will build in connection strength then fall to 0% connectivity after a few seconds. This cycle repeats indefinitely. I have tried every setting on my phone and in the app to remedy this problem, but it does not change anything. It does display top speed however.
