Repeats the same time over and over, but it seems reasonably close to what it should be (per motor trend and other sources). I don’t know if the gps in my phone is unable to refresh fast enough to make the difference, or if the app is not very precise. Good for getting an idea of what your car can do, not good for getting a real time.

I really wanted to Love this app! I have a Ford Explorer Platinum 3.5L eco boost. It has a CAI and a Performance tune for 93 octane. It should be in the upper 4’s to lower 5’s. Mid 5’s with a bad pass, but it is all over the map on the same surface. 3.96 good hit with good hook, tire hop in 2nd, but seriously, no way!!!5.82 another good hit but tires bounced in 2nd6.00 bad hit, slipped on the start and bounced into 2nd (weird to get exactly 6.00 too IMO)5.46 with wheel slip and tire hop at 2nd5.96 good hook and no bounce into 2nd, had to pedal it slightly to avoid that. As much as I would love it if it actually did the 3.96, it didn’t. And, all of the other times weren’t consistent enough with very similar passes. It’s a good app to get a feeling of where the car might be, but definitely needs refining. I can keep my Corvette within .10 about 90% of the time with its onboard calculator.

Don’t even bother downloading lol. Tried to see if I could use it for my built bmw 535i, but it only brings you to the loading screen that says “select vehicle” then tells you there’s a network issue no matter what you try. Honestly don’t wast your time, I tried with Wi-Fi and without. Neither worked it just keeps you on the same screen telling you there is an issue with network connection. It’s a completely useless app. 👎🏼(I read and other people had this exact same issue I’m having, so it must be common)

The app doesn’t provide the Tesla Model Y options. I guess developer should update the app. Or just allow to key in any model if one cannot be found in the list. Also would be nice to be able to use this app for multiple cars. Either profile of the driver should allow to keep and choose from multiple cars OR app to switch between profiles of the cars.
