Apple Watch Swimming App
Your swim workout, pace clock, and live guidance on your wrist.
Plan a structured session on iPhone, send it to Apple Watch, and keep intervals, rest, pace, and heart-rate zones visible while you swim.
More than recording distance after the swim.
Swimio is designed for the part of training that happens between pushing off and touching the wall: remembering the set, watching the interval, managing rest, and staying on pace.
Structured workout guidance
Keep the current set and interval on your wrist so you can follow the session without paper, a phone on deck, or memorizing every repeat.
A live swimming pace clock
See pace, work, and rest timing during the workout. The information stays close enough to check between repeats without breaking the session flow.
Metrics you can customize
Choose the watch pages and metrics that matter for your session, including pace-clock, heart-rate, and workout-guidance layouts.
Plan on iPhone. Swim from Apple Watch.
The phone handles planning and review; the watch keeps the right instructions and metrics available in the water.

Build, generate, or import
Create the workout visually, use AI Coach, paste a text set, or turn a coach whiteboard photo into a structured session.
- 02

Sync the workout to Apple Watch and choose how guidance, pace, and heart-rate information appear during the swim.
- 03
Review the completed session
Afterward, use iPhone to examine pace, splits, distance, stroke insights, training load, and readiness in one place.
Built for the rhythm of pool training.
Pool workouts are made of changing distances, repeats, intervals, and rest. A useful Apple Watch swimming app needs to do more than start a timer: it should make the structure of the session easier to follow when attention belongs on the swim.
Swimio keeps planning on the larger iPhone screen and moves the essential cues to Apple Watch. Live interval information and a wrist-based pace clock reduce the need to look across the pool or reconstruct a set from memory.
When the workout is finished, HealthKit sync and post-swim analysis connect what happened in the water to your broader training history. That gives AI Coach and readiness insights better context for the next session.
