it’s not fking work, waste my money for non working app
App doesn’t work
Mph works fine but doesn’t log 1/4 mile or 60 ft times. Got a green bar every time I use it meaning it has a good signal
Easy to use!
Update 2026-06-23: I sent the author an email asking if this was strictly GPS or also used the much more accurate accelerometer in my phone. No answer. 🫤 I consider it a fun toy only.
Original: This is a *very* easy to use app! I’m not sure how accurate it is yet, as I’ve only used it two or three times and don’t have anything else to compare it to (now that LapTimer has been disabled by BMW on my M550i — argh 😠).
