Swimming Lap Tracker

Swimming Lap Tracker turns your Apple Watch into a fast lap counter and swim log. Mark laps with the Digital Crown or Action Button on the Apple Watch Ultra, and review detailed stats on iPhone.

Key features:

- Fast lap marking with Digital Crown or Action Button (Apple Watch Ultra)
- Manual Lap Mode for start/stop lap timing and rest
- Live metrics: lap time, total time, distance, lengths, strokes, heart rate
- Pool length presets or custom length (1m to 250m)
- Open Water Mode with GPS distance
- Post-swim analysis on iPhone with pace, motion charts, calories, and location labels
- Motion data review and CSV export
- HealthKit sync

Set your pool length or switch to Open Water Mode, tap Start Swim, and focus on your workout while every length is captured manually by hand and therefore accurately.

Permissions: Health is required. Motion and Location enable motion tracking, recording the location of your swims, and open water distance.

Requires iOS 18.2+ and watchOS 11.2+

Important – if using Apple Watch Ultra, after installing the app, open settings in WatchOS. Scroll down to “Action Button”. For the app choose “Swimming Lap Tracker”. Tap on “First press” then select “Start a workout”. Then for workout choose “Swim Laps”. If you wish to use the Action Button for lap tracking, you must first open the Swimming Lap Tracker app using the Action Button. Otherwise lap incrementing with the action button may fail.
