Other apps have gps start which is a more useful feature. ### 3/5 — Love the app except…. *2023-05-23, version 3.3* Loving the app and am thinking of purchasing to get all features. The main thing holding me back is some parts of the app are not fully working. Like registering my account to login. Also it’s not saving some setting. That may be fixed when logged in but it won’t let me. For that reason I am giving only 3 stars. ### 2/5 — Instructions *2023-05-08, version 3.3* I just tried to test my times, but couldn’t figure it out. It says it is “hands free”, but mine has a start button. It’s kind of annoying to have to manually start the timer and get the car running at the same time. Then it said that I have to record my times, but I don’t see a way to do that. Ideas? Instructions would be helpful. ### 3/5 — Few bugs? *2022-03-15, version 3.3* Leaderboard doesn’t work ### 2/5 — Facebook connection *2022-03-06, version 3.3* Will not let me connect my Facebook to the app even after uninstalling and reinstalling ### 1/5 — Trash *2021-12-22, version 3.3* Deleted it minutes after installing due to the app not connecting to my network. CRAP! ### 1/5 — Garbage app! *2021-12-13, version 3.3* Don’t waste your time and gas trying to get a 0-60 time on this app. It doesn’t work! ### 4/5 — Richard *2021-11-28, version 3.3* Great piece of kit, easy to use and interesting to see other users times. ### 1/5 — Doesnt work *2021-11-01, version 3.3* Doesnt even track my time ### 3/5 — Great concept. Not even collide to accurate *2021-09-02, version 3.3* 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 2nd 6.00 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 2nd 5.96 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. ### 3/5 — No Model Y! *2021-08-14, version 3.3* 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. ### 1/5 — Stupid units *2021-07-14, version 3.3* Sorry. Deleted this 2 min after downloading. Can’t take it seriously if it uses ridiculous units. Kmph ? Really? It doesn’t exist. ### 4/5 — need Russian models *2021-03-08* lada, uaz... ### 1/5 — Poor *2021-01-28, version 3.3* Very inaccurate. Did 0-60 in eco mode and it said 9.9 secs. Did the same in sport mode, which was far quicker and it said 15.5 !! GPS based accelerometer so unlikely to be wholly accurate, but this was wildly out. Deleted. ### 3/5 — No sound? *2020-10-01, version 3.2* So I am the only one to think that you need sound for ready, set, go?? Only visual guidance doesn't work and it's unsafe. ## Most critical reviews (10 lowest-rated) ### 1/5 — Doesn’t work for 0-60 on Aston Martin *2025-12-11, version 3.4* Doesn’t work, don’t waste time ### 1/5 — Doesn’t even have my car? *2025-03-28, version 3.4* I have a Tesla Model Y Performance and they don’t have an option for that. It’s funny that it makes you even choose a car? like why? It’s funny because they have the option for a Model 3, Model S and X and even a cybertruck?? like seriously? the worst tesla is on there? But not the most sold one? ### 1/5 — Low accuracy *2025-02-15, version 3.4* It did not say I hit 60 mph until I was at >75 mph. Don’t trust the accuracy ### 1/5 — Don’t trust this app *2024-05-06, version 3.3* Went to test my Porsche after doing a ECU stage 1 and TCU stage 1. The numbers are exactly the same before the Flash. I can sense way more speed and way more toeque. But this app does nothing that presenting the std info that you can find in a magazine. ### 1/5 — Horrible app *2023-11-16, version 3.3* I have tuned 06 mustang, Press gas and a get 60 and app only after 3 seconds show me 60mph when a I already had 100mph, so inaccurate ### 1/5 — Innacurate *2022-11-23, version 3.3* Getting 5.05 0-60 on Audi S4 (after remap) when dyno says 3.6 and plug in diagnostics 0-60 says 3.8 ### 1/5 — Terrible, doesn’t function *2022-08-11, version 3.3* 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) ### 1/5 — Bahahah *2022-07-08, version 3.3* This app no where even close its very unaccurate ### 1/5 — It doesn’t load *2022-06-18, version 3.3* When you try to log in thru Facebook it just buffers. When you try and use the app not logged in it doesn’t work either. ### 1/5 — Problem *2022-04-24, version 3.3* I installed aplication and I can’t select vehicle „Couldn’t connect to network; Please verify your network connection, tap ok to try again”. I tried uninstall and install again but this not working ## Most praised reviews (10 highest-rated) ### 5/5 — Setting Ignition Timing *2025-09-30, version 3.4* Great help setting the ignition timing fir my 60 year old Austin Healey. ### 5/5 — Speedometer matched *2022-01-24, version 3.3* I was shocked to see how accurate the speed readings were compared to my speedometer, off by a bit when accelerating fast but that’s a given with gps. Fun app, well designed. ### 5/5 — Who da thunk it *2021-06-19, version 3.3* Absolutely classic!!! Easy to use and insightful. You wouldn’t believe it but your not as fast as u think u are. Spinnin ain’t winnin======~ ### 5/5 — Works but *2021-02-12, version 3.3* It needs sound ### 5/5 — Incredibly accurate little app! *2020-04-24, version 3.2* In a head to head shootout vs Dragy, this app came out on top for being the most accurate. ### 5/5 — Seems dead accurate . Highly recommend! *2020-03-21, version 3.2* Tested my golf r with dsg . Came back at 0-60 5 secs but I had the mrs in the car with me so I reckon without the extra weight I would’ve defo hit the manufacturers claimed 4.6secs . Not sure I hit the accelerator full either so shall be testing again. Seems dead accurate and probably the only way I’ve found for the average person to test their car . Got a quick car then I highly recommend this . Free as well so it’s a bit of a no brainier . ### 5/5 — Fantastic *2019-09-27, version 3.0* They didn’t have my model of car on the list so I emailed them and they got back to me within days! Very happy and app works great. ### 5/5 — Absolutely love it *2019-09-21, version 3.0* love it! would be nice to have a way to share my times on social media ### 5/5 — Sick!! *2019-09-17, version 3.0* Been looking for something like this!! ### 5/5 — Great *2019-09-13, version 3.0* Meet me on the leaderboard --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
