Cooldown

Multi-service workout data management for the modern athlete

Pull your training together from Apple Health, Peloton, WHOOP and Garmin — then correct what recorded wrong, merge overlapping recordings into one complete workout, keep your own archive of every file, and send the result on to Strava, Garmin Connect, intervals.icu, Runalyze, COROS and Dropbox.

Every service wants to own your training. None of them talk to each other.

So a ride sits in Peloton, a run sits on your watch, and the recovery app sees neither. Cooldown is the hub in the middle: it collects them, lets you fix and merge what came through wrong, and sends one complete workout back out to everywhere you actually train.

Your training data, under your control.

Every Service, One Workout

Your training arrives in pieces: Apple Health from your watch or phone, Peloton and WHOOP behind their own apps, a Garmin in its own silo. Cooldown pulls all of it into one library, then sends the finished workout out to Strava, Garmin Connect, intervals.icu, Runalyze, COROS and Dropbox — without re-entering anything by hand.

Automatic, Ongoing Sync

Set a rule once — every new run to Strava — and new workouts route themselves whenever you next open Cooldown. Anything a service refuses stays queued and retries later.

Bulk Sync Your History

Select a day, a month, or years of past workouts and push them all at once. Cooldown checks what's already on the other end first, so nothing ends up duplicated.

Fix What Didn't Record Right

GPS drift, a watch that started late, a distance that's clearly wrong — correct it once, and the fix travels with the workout to every service it syncs to.

Route Shape & Pace Map

Every run shows the shape of its route at a glance, and opens into a full pace-colored map with splits, heart rate, cadence, power, stride length and ground contact time.

Rename Once, Everywhere

Set a naming template once — time of day, activity type, day of week — and every workout arrives with a consistent name in Health and on every service it syncs to.

Merge Two Recordings Into One

Watch on your wrist, Peloton counting cadence and output? Cooldown spots the overlapping recordings and merges them — heart rate from one, power and cadence from the other — into a single complete workout.

Share Cards Worth Posting

Turn any run into a poster-style image — your route as a glowing line over an illustrated scene or a stylized street map, with the stats you choose.

Backed Up, Twice

Every workout can be archived as a standards-based file — kept locally in the app, and mirrored to a folder in your Dropbox — so your history outlives any single phone, watch, or service.

Questions people actually ask.

How does Cooldown keep my workouts in sync across apps?

Cooldown reads your workouts from Apple Health and imports the ones that never reach it — Peloton rides, WHOOP activities, Garmin recordings — into one library. From there it pushes them out to Strava, Garmin Connect, intervals.icu, Runalyze, COROS, Dropbox, or a webhook you configure, so nothing stays trapped in one app.

Do I have to manually export every workout myself?

No. Turn on automation and set a rule — every new run to Strava, say — and from then on new workouts route themselves the next time you open Cooldown or pull to refresh. iOS doesn't let apps run freely in the background, so syncing happens when the app is open; opening it after a workout is enough. If a service is unavailable, the workout stays queued and Cooldown retries on later opens. Automation only acts on workouts recorded after you turn it on, so your existing history is never mass-uploaded.

Can Cooldown fix the distance on a GPS run that measured wrong?

Yes. Edit the distance or duration on any workout, and the correction travels with it to every service it syncs to — including a corrected distance stream in the TCX file Strava receives, so Strava's own display reflects your fix rather than the raw GPS track.

Does Cooldown change the workout in Apple Health?

No. Workouts recorded in Apple Health can't be modified in place by other apps, so Cooldown keeps your edits — name, notes, corrected distance/duration, trims — in its own local overlay on your device. Health's original record is never touched; Cooldown just applies your corrections whenever it renames, syncs, or displays a workout.

Do I need my own Strava API application?

No. Cooldown ships with its own registered Strava app, so connecting is just the standard Strava sign-in. Advanced users who'd rather use their own Strava API credentials can still do that from the Strava connection screen.

Is my workout data private?

Yes. Cooldown has no user accounts, no analytics, and no ad tracking. Your workouts and edits are stored locally on your device. When you connect a service like Strava, your workout data goes directly from your device to that service using your own account.

My Watch and my Peloton both recorded the same ride. Which one wins?

Both — that's the point of merging. Cooldown notices when two recordings from different sources overlap and offers to merge them, taking heart rate from your Watch and cadence and power from the bike, so one complete workout goes to Strava instead of two partial duplicates. The originals stay untouched in Apple Health, and you can unmerge any time.

How do the Peloton and Garmin connections work?

Peloton and Garmin don't offer public APIs, so Cooldown signs in the same way their own websites do: you enter your password on their login page shown inside the app — Cooldown never sees or stores it, only the signed-in session. Because these connections are unofficial, they can stop working if Peloton or Garmin change their services; Cooldown says so in the app rather than pretending otherwise, and updates are shipped when that happens.

What does Cooldown cost?

Everything that brings data in or works on it is free forever — your library, renaming, corrections, merging, imports, stats, share cards and file export — plus 10 free exports so you can try sending. Cooldown Pro unlocks unlimited sending and automations: $3.99 per quarter, $9.99 per year, or $34.99 once for lifetime.

Your workouts stay on your device

Cooldown has no accounts, no analytics, and no ad tracking. Your workout edits are stored locally, and data only ever leaves your device when you connect a service — going straight from your phone to that service, using your own login. Read the full privacy policy.
