About

Lappy listens for location updates from OwnTracks on your phone. It processes that data to display an estimated lap count.

Reliability varies from phone to phone. Test before the event, and count with your watch.

Usage

• The live page displays only today's data
• Lap counts are fractional and ignore direction and start/end location
• Your location displays as a marker while you're on the course
• Rows show a warning icon ⚠️ if they contain frequent GPS errors greater than 20m. Check your configuration, and keep your phone in an outer pocket if possible.

Privacy

The client app reports GPS, network, and battery percentage information within the geographic bounds of the course. Read more about how we handle your data in the privacy policy.
