Swim Sage

Your swims, read properly.

Swim Sage reads the pool swims your Apple Watch records in Apple Health and shows how you are really getting on: your pace and efficiency, measured against your own normal, not someone else's.

£0.99, once. For iPhone, iPad, Apple Watch and Apple Vision Pro.

The tour

Everything your Watch records, read properly.

Screens show the sample swims anyone can try in the app.

Today

Your latest swim, at a glance.

The time, distance, lengths, heart rate and pool on one face, with every length's pace as a bar against your typical pace. Swipe back through earlier swims, and press and hold to see what changed since the swim before.

Swim Sage, Today: Your latest swim, at a glance.
Swim Timeline

See the swim, not a table.

Replay your swim in a pool, length by length, with a swimmer at your target's pace in the next lane and your best and slowest recent swims beside you. Watch where you got ahead and where you fell behind.

Analysis

How the swim unfolded.

The moments that mattered, in order: your largest deficit and lead, your fastest and slowest ten lengths, and when you reached your target. Then your pace by section, against your own median.

Progress

Progress, like for like.

Distance, pace, SWOLF, strokes per length and heart rate over weeks, months and years, compared only with swims in the same pool length, because turns change everything. Records, streaks and a report for each month.

Corrections

Fix what the Watch got wrong.

Wrong pool length, a slow first length while you set off, two lengths merged into one: correct them, and Swim Sage keeps your corrections on top of what Health recorded, without changing Health.

Targets

Targets that mean something.

Set a target the way swimmers think of one: 70 lengths within 40 minutes, at least 1,800 m, or a pace to beat. Every swim is judged against it. Swims from before you set one can be filled in from the round numbers you were already swimming.

Swim Sage, Targets: Targets that mean something.
Ask

Ask about your swims.

Typed or spoken: "How far did I swim this month?" Answers come from your own swims, worked out on your iPhone, never sent anywhere. Weekly and monthly reports are waiting when you want them.

Swim Sage, Ask: Ask about your swims.
Challenges

Challenge a friend.

Through Messages: beat a swim, or swim further this month. You choose exactly what is sent, and nothing goes automatically. Your friend needs Swim Sage to accept.

Wherever you swim

On your wrist, your desk and your table.

Choose a target before you swim and get quiet cues as you go: ahead, behind, and when you have reached it.

Your devices, in step

Your iPhone, iPad and Apple Vision Pro sync corrections, targets and challenges directly, over your own network.

You're on Apple Vision Pro

Apple Vision Pro

Race in 3D.

On Apple Vision Pro, Swim Sage is a native app, and the race replay is a pool in your room: a tiled pool tilted towards you, one lane for each swimmer, the places beside each lane with the leader in gold, and the player beneath it. Your swims arrive on the headset through Apple's own iCloud Health sync.

Questions

Before you buy.

What does Swim Sage need?

Pool swims recorded by an Apple Watch in Apple Health, with Apple's Workout app or Swim Sage's own Watch app, and an iPhone on iOS 26 or later. Open water swims are listed and counted, without length timing.

How much is Swim Sage?

£0.99 in the UK, paid once; the App Store sets the price elsewhere. No subscription, nothing sold inside the app, no advertising.

Does Swim Sage change my Apple Health data?

No. It reads your swims and keeps your corrections on top of what Health recorded, without changing Health. The only thing it ever saves to Health is a swim you record with its Watch app, as Apple's Workout app does.

What is my typical pace?

The median pace of your swims in the 30 days before a swim, in the same pool length, once there are at least three. Pace is swimming time per 100 metres or yards, rests left out. Every comparison in Swim Sage is against you, never an age table.

Can it fix a swim my Watch got wrong?

Yes. Open the swim and tap Edit to set the pool length, trim the start or end, fix a slow first length, or merge and split lengths. The Check list on Swims suggests fixes it thinks are likely.

Can I try it without any swims?

Yes. On the empty Today screen, tap Try with sample swims to see every feature with made-up swims. Nothing done with them is kept, synced or sent to the Watch.
