Create downloadable spoken Standard or Waltz audio guides with Piano cues for tempo training on compatible swimming headphones, plus equipment tracking on Apple Watch.
Swimming Lap Tracker gives you precise manual control over laps, intervals and structured swim training on Apple Watch, with detailed workout analysis on iPhone.
Mark laps with the Digital Crown or the Action Button on Apple Watch Ultra. You decide exactly when each lap or interval is recorded instead of relying on automatic lap detection. Live swim metrics stay visible on your wrist, and completed workouts are saved to Apple Health.
BUILD CUSTOM SWIM SETS
Create structured training sessions in the Set Builder and sync them to Apple Watch.
• Build workouts with multiple named stages
• Set distance or repeats with a separate interval distance
• Choose stroke, drills, equipment, rest and notes
• Add breathing targets and bilateral breathing
• Set target pace and cadence in seconds per stroke or strokes per minute
• Reorder stages and save multiple training sets
• Follow stage-by-stage prompts and progress on Apple Watch

DOWNLOADABLE AUDIO GUIDES
Create a downloadable audio guide for a custom workout before you swim. Voice prompts and timing cues support pace and tempo training.

Download or transfer the finished audio file to compatible swimming headphones with onboard storage. Audio guides do not play through swimming headphones over Bluetooth while you are in the water.
EQUIPMENT FOR EVERY SESSION
Select equipment in supported Apple Watch workout modes, including fins, paddles, pull buoy, kickboard and snorkel. Your choices persist between workouts, the live screen shows a bag icon with the selected item count, and completed workouts show equipment as capsules in iPhone history.

I have a few issues with the app. The first is that settings isn't nearly impossible to navigate because the digital crown changes pool length instead of scrolls you through the settings. Second issue is that I cannot set the distance to yard for my pool, which basically makes the app unusable. The third thing is that I'd like to be able to see the average pace per 100 yard, not just total time for the different sets.
Developer Response
Thank you very much for your review and feedback.I am pleased to confirm imperial yard measurements and pace per 100 has now been added to the latest version 1.22 of the app. Please update the app and reconsider your rating if you feel this improves your experience. Regarding the scrolling in the settings screen, it's recommended to scroll through that screen with a vertical touch motion, when the device is unlocked and not in water mode, but I am looking on ways to improve this.Please feel free to email info@mobileappz.co.uk if you have any further valuable feedback or suggested improvements. Kind regards,Chris
