Connect your Apple Watch
Apple Health doesn't offer a cloud API, so your iPhone sends the data to Plait for you. Generate a private sync link below, then set up a daily automation with either the Health Auto Export app or the free Plait Shortcut. Plait turns your HRV, resting heart rate, sleep and activity into recovery, strain and sleep insights.

Sync status
Step 1 · Your private sync link
This link is unique to you and acts like a password: anyone who has it can add data to your account. Generating a new one disables the old link.
Step 2 · Set up a daily sync
Health Auto Export is a paid iOS app that can POST your Health data to a URL on a schedule. It's the most complete option (it includes heart-rate and sleep-stage detail).
- Install Health Auto Export from the App Store and grant it access to Apple Health.
- Open Automations → tap + → choose REST API.
- URL: paste your sync link from Step 1. Method: POST. Format: JSON.
- Data type: Health Metrics. Aggregate: Days. Also enable Workouts if offered.
- Metrics to select:
Heart Rate VariabilityResting Heart RateSleep Analysis Active EnergyBasal Energy BurnedStep Count VO2 MaxRespiratory RateApple Exercise TimeHeart Rate
- Sync cadence: daily (e.g. 9:00 AM, after your watch has synced overnight). Period: Previous day or Today both work — Plait merges by date.
- Tap Export now once to test, then check the sync status above. For history, run a one-off manual export covering the last 30 days.
Tip: keep the payload under 5 MB per request. If you export several months at once, use the "Days" aggregate rather than minute-level data.
The Plait Shortcut is free and uses Apple's built-in Shortcuts app. It reads yesterday's Health data and sends a compact summary to your sync link.
- On your iPhone, open the shortcut link: Plait Apple Watch Shortcut — coming soon (use Health Auto Export for now) and tap Add Shortcut.
- Run it once. When asked, paste your sync link from Step 1 and allow access to Health.
- Open the Shortcuts app → Automation tab → + → Time of Day.
- Pick a time (e.g. 9:00 AM), Daily, and choose Run Immediately (turn off "Ask Before Running").
- Select Plait Apple Watch Sync as the shortcut to run. Done — your dashboard updates every morning.
Building your own shortcut? Here is the JSON it should POST
One object per day, Content-Type: application/json, minutes for sleep fields, kcal for energy:
{
"source": "shortcut",
"date": "2026-03-10",
"hrv_ms": 58, "resting_hr": 52,
"sleep": { "start": "2026-03-09T23:10:00-05:00", "end": "2026-03-10T06:45:00-05:00",
"asleep_minutes": 430, "deep": 65, "rem": 95, "core": 270, "awake": 25 },
"active_kcal": 540, "basal_kcal": 1650, "steps": 9800,
"vo2max": 44.1, "respiratory_rate": 14.8,
"workouts": [ { "type": "Outdoor Run", "start": "2026-03-10T07:00:00-05:00",
"end": "2026-03-10T07:40:00-05:00", "kcal": 320, "avg_hr": 151, "max_hr": 178 } ]
}
What Plait does with it
- Recovery (0-100): your HRV vs your 30-day baseline (50%), resting heart rate vs baseline (25%), and sleep duration/consistency (25%). Expect it to settle after 3+ days of data.
- Strain (0-21): from active calories and workout minutes.
- Sleep: in-bed time, deep / REM / core stages and efficiency.
Your data stays private to your Plait account. Beta: things may change; email support@plait.fit with feedback.
