By far the best lap timer app I've found. UI is pretty good, it shows you a ton of interesting data, and it's pretty easy to use.

Used this for timing and video at my first track day at Lakeside raceway in Aus. For that case it was great. Thank you for making this available for free. :)

Great free app with tons of extras. Has my local tracks and easy to use.

No updates in 3 years, but still taking money for race render premium? Seems a little dishonest. Bought a Race box Mini S after reading that it was compatible in the app, only to find out you need a separate 3rd party app to facilitate (GPS Connector), and BLE is a paid upgrade. Getting constant crashes while using NBP for a wideband o2 sensor, and there's no support whatsoever.

Would put zero stars makers are crooks and anything older than the newest version will no longer connect do not buy ever soon version 4 will come out then version 3 will cease to function owners are crooks

Used to be great. Something changed in the past few years and the app will crash after logging for a minute at the most. Now just crushes before I even try to open it. Seems to be related to having Bluetooth GPS enabled in the settings. Crashes don't seem to happen on my spare iPhone, only on my Android. Issue happens on multiple Android phones I own, so it's not one specific phone. Sucks because I bought a haze GPS solely to use on track addict, and it's android only.

Can't use this app with my OBD2 BT scan tool, and it also won't connect the HP Tuners RTD device I have. I've used several monitoring apps over the last year with my scan tool without a problem. Was prepared to ditch them all and just use this app after I got the RTD, but after days of trying to connect, reset, turn off, forget, pair, and stuff around with endless combinations of the above, I have now given up.
