Your whole workout history in one place.
Whether your workouts live in Apple Health, Garmin, Strava or another service, Cooldown pulls them into one library, de-dupes them into a single source of truth, fixes what recorders get wrong, and sends the result on to the services you train on. Then it shows you the whole picture: charts, heatmaps, records, and a recap film of your week.

Every workout, in one place. Then everything you can do with it.
The Whole Picture, Any Period
How this year compares with last, how the month is going, where your pace sits against distance, your records and best efforts, and every route you've ever recorded on one heatmap. Pick a period and a sport, scrub any chart, and the numbers roll over as you go.
Recordings Go Wrong. Fix Them Here.
Trim the minutes you forgot to stop the watch. Split one recording into two, or combine back-to-back segments into one. Merge a Watch recording with a phone app's from the same session and keep the best of both. Cooldown spots the duplicates and suggests the fix. Nothing is deleted; every edit is undoable.
Logging Miles on Memory Lane
Cooldown finds every photo you took during a workout and pins it to the exact time and place on your route, across years of history, with no tagging. Tap a pin to open the photo. Private by design: it uses your library's own metadata, and no photo ever leaves your phone.
Set It Once, Forget It
When a workout arrives, upload it, back it up, or merge it with the same session from another app, automatically. iOS can wake Cooldown when Health records a workout, so a run is usually ready minutes after you finish, with a notification when a rule wants your say.
Record Straight From Cooldown
Start a run or ride from the app with GPS, connected Bluetooth heart-rate, cadence and power sensors, and spoken splits. It lives in the Dynamic Island while you go, and lands in Apple Health like any other workout.
Recap Films and Share Cards
The Recap tab plays your week, or month, back as a short film of your routes, ready to share. Any single run becomes a poster-style card: your route as a glowing line over an illustrated scene or a stylised street map, with the stats you choose.

No account. Your workouts stay on your phone.
Cooldown has no account, and no server of ours ever stores your workouts. They stay on your phone, and one leaves only when you send it to a service you've connected. Photo matching runs entirely on the device, so no photo is ever uploaded. Read the full privacy policy.
Coming soon to the App Store.
