How do I time a lap?
Tap a driver's card on the Timing tab. The first tap starts the timer, each next tap records a lap. After a lap the finished time stays on screen for 10 seconds while the next lap keeps timing.
Can I use the volume buttons?
Yes. Turn on Settings → Volume Keys. On the Timing screen, Vol + records a lap for Driver 1 and Vol − for Driver 2. The screen must be unlocked.
How do I rename a driver?
Long-press the driver's card.
Why does the app ask for my location?
Only to fetch the current weather when you save a tyre reading. It is optional. See the privacy policy.
Where is my data stored? Is there a backup?
Only on your phone. There is no cloud sync. You can export a session from its details screen.
How do I delete everything?
Settings → Delete all data. This cannot be undone.
