Garmin watch app

Updated 5 min read, plus 1 min of exact calculation

Short answer

The MyBodyAI watch app is a small app for Garmin watches, installed from the Connect IQ Store. It is an app, not a watch face, and it draws MyBodyAI's own scores only, never Garmin's. You pair it with a 6-character code generated in Settings, section "Devices", and from the wrist it sends the day's stress, Body Battery and recovery time.

  • The code: valid for 24 hours, works once, and a new code cancels the old one. Enter it in Garmin Connect under "Pairing Code", then open the app on the watch: it shows "Paired", or "Code rejected" when the code was wrong or expired.
  • One watch is paired to an account at a time, and pairing another replaces it. "Unpair watch" cuts a watch off at once, so unpair one you lose or sell.
  • Six screens: Training readiness, Energy map, Readiness drivers, Health, Sleep debt and Biological age.
  • Freshness: numbers about two hours old are drawn as stale, and the next swipe tries to refresh them.
  • What it sends: the day's stress, the Body Battery curve and Garmin's recovery time, and nothing else. On the free plan the watch receives only the day's Body Status verdict.

The Garmin watch app#

A small MyBodyAI app for Garmin watches, installed from the Connect IQ Store. It is an app, not a watch face. It draws MyBodyAI's own scores only, never Garmin's, and it sends your day's stress, Body Battery and recovery time from the wrist. The store page lists the watches it installs on, and if your model is not there, a code will not help.

Pairing#

  1. Open Settings, section "Devices" ("Zařízení"), the card "Garmin watch app (Connect IQ)", and press "Generate pairing code".
  2. The card shows a 6-character code ("Pairing code") and "Expires in {time}". The code is valid for 24 hours, works once, and a new code cancels the old one. It uses letters and digits without 0, 1, I and O, so it is easy to read. "Copy" copies it.
  3. In the Garmin Connect mobile app, open MyBodyAI, then Settings, then "Pairing Code" and paste the code.
  4. Open MyBodyAI on the watch itself. The setting travels over Bluetooth, but the app picks it up only when it runs. The watch shows "Paired", or "Code rejected" when the code was wrong or expired.

Then the card says "A watch is paired" with the date. One watch is paired to an account at a time, and pairing another replaces it. "Unpair watch" asks "This stops the paired watch immediately." and cuts it off: the key stops working, sending stops, and the watch app asks to be paired again ("Not paired: get a code in the MyBodyAI app, enter it in Garmin Connect"). Unpair a watch you lose or sell.

Exact calculationSettings in Garmin Connect

In Garmin Connect, the app's settings hold "Pairing Code (from web app)", "Sync Mode" ("Manual" or "Automatic", automatic by default), "Sync Interval" (15, 30, 60 or 120 minutes, 120 by default) and "Language" (English or Čeština).

The six screens#

You move between them with a swipe or the up and down buttons. Each draws only your MyBodyAI numbers.

  1. Training readiness (the home screen): a dial with the zone word, what lifts and drags it in points, the sleep debt and how long ago the data were fetched.
  2. Energy map ("ENERGY MAP"): the day's energy curve with the best time to train and a marker for now, as on the app's energy map (see Morning energy).
  3. Readiness drivers ("DRIVERS"): up to five rows, Recovery, Sleep, Energy, Stress and Load, biggest mover on top. SELECT switches between the influence in points and the raw 0 to 100 component.
  4. Health ("HEALTH"): the body figure in the color of today's Body Status and six rings, Nerves, Heart, Immunity, Breathing, Recovery and Resilience. SELECT, or a tap on a ring, opens that system's detail, where up and down cycles through the six and Back returns.
  5. Sleep debt ("SLEEP DEBT"): the debt in hours on a 0 to 8 h+ scale and the last seven days.
  6. Biological age ("BIOLOGICAL AGE"): your biological age against your calendar age and the six domains on a radar, with "low confidence" when the model is unsure.

A small glance on the watch shows a readiness teaser.

Controls and freshness#

Exact calculationButtons and how fresh the numbers are

SELECT starts a sync on screens where it has no other job. BACK goes home or leaves. MENU (a long press of the middle-left button, or the touch menu gesture) opens "Settings" with "Refresh interval" and "Language". The bottom row shows how old the data are ("right now", "5m ago", "3h ago", "2d ago", "stale"). When the numbers are about two hours old they are drawn as stale, and the next swipe tries to refresh them.

What the watch sends#

The watch sends back the day's stress (average, maximum and the hours covered), the Body Battery curve (morning peak, latest level, charged and drained) and Garmin's recovery time in hours. These are the three things Health Connect cannot carry, so for them the wrist is the only source. Nothing else leaves the watch: no all-day heart rate, no location, no activity files. It sends at the sync interval you chose. It reads your scores with its own key, which you cancel by unpairing.

On the free plan the watch receives only the day's Body Status verdict, and its other screens stay empty.

Frequently asked questions#

The watch says "Code rejected".#

The code is wrong, expired (24 hours) or already used. Generate a new one in Settings, section "Devices", enter it under "Pairing Code" in Garmin Connect, and open the app on the watch.

Does the watch app measure my HRV or heart rate?#

No. It draws your MyBodyAI scores and sends stress, Body Battery and recovery time. Your heart rate and sleep reach us through your Garmin link or the phone (see Devices).

Why are the other screens of the watch app empty?#

On the free plan the watch receives only the day's Body Status verdict, and its other screens stay empty. What each of the six screens shows is in The six screens, and what the watch sends back is in What the watch sends.

Can I pair more than one watch?#

No. One watch is paired to an account at a time, and pairing another replaces it. "Unpair watch" cuts a watch off at once: the key stops working and sending stops, so unpair a watch you lose or sell. See Pairing.

Did this page answer your question?

Thresholds, windows and calculations in the Encyclopedia are tied to the app's code by an automatic test: when one changes in the app, the test makes us correct the entry. MyBodyAI is a wellness app, not a medical device. It does not diagnose. If you feel unwell, ask a doctor.
