Can Aera use my Garmin, Oura or WHOOP data?

Aera does not read your tracker. It reads Apple Health. Whatever your watch, ring or band writes into Apple Health on your iPhone, Aera can explain against your own normal. Whatever stays inside the maker's own app, it cannot see.

So the useful question is not "does Aera work with my brand?" but "does my brand put the data I care about into Apple Health?" This page shows what Aera does with what arrives, and what to check.

One honest caveat: we have read how Aera handles other trackers' data, but we have not yet tested it with a Garmin, Oura or WHOOP on a real device. Treat the brand names below as examples of how it should work, not as a tested compatibility list.

What Aera does with data from other trackers

• Workouts. Runs and sessions from Strava, Garmin, Nike and similar apps that reach Apple Health are read. If the same run was recorded twice, for example by an Apple Watch and a second app, Aera counts it once, so your training load is not doubled.
• Sleep. If several sources log the same night, Aera picks the single fullest one that has sleep stages and does not blend them. Overnight heart rate and HRV also come from one source per night.
• Strava history. In Settings, Import from Strava reads your Strava export file (GPX, TCX and FIT activities), without an account.

What may not reach it

What a tracker writes to Apple Health is the maker's choice, and it changes. From the makers' own descriptions and independent comparisons we know of, as of October 2026:

• Oura and WHOOP write sleep to Apple Health, but not HRV. WHOOP's stated reason is that Apple Health stores HRV as SDNN while WHOOP uses RMSSD, a different calculation.
• Garmin sends sleep, heart rate and workouts, but not the route (GPS track) of a workout.

Aera can only explain what it receives. If a number never reaches Apple Health, there is nothing for Aera to explain, and that screen will stay empty rather than guess. Check your tracker maker's current Apple Health page, because these lists are theirs to change.

How to connect

1. In your tracker's own app, find its Apple Health setting (usually under Settings, in a section called Apple Health or Connected apps) and allow sleep, heart rate and workouts.
2. To see exactly what it writes: open the Health app, tap your profile picture, then Apps, and open your tracker's app. Each type it writes is listed.
3. Open Aera and allow Health access. Sleep and training numbers appear as the data comes in, and Aera tells you when it is still building your normal.

Do I need an Apple Watch?

No. Workouts can come from another device or app. Sleep does need a wearable: an iPhone on its own usually logs only time in bed, and a night with no asleep data from any source is not counted. A watch, a ring or a sleep app that writes sleep to Apple Health fills that in. The Apple Watch app is an optional companion for live runs and turn-by-turn routes.

Quick answers

Does Aera work with Garmin?

Aera reads Apple Health, and Garmin Connect can write sleep, heart rate and workouts there. Aera reads workouts from Garmin that reach Apple Health. It has not yet been tested on a real Garmin account, and Garmin does not write the GPS route of a workout to Apple Health.

Does Aera work with Oura or WHOOP?

Both can write sleep to Apple Health, and Aera reads it from any source. According to the makers and independent comparisons, neither writes HRV there, so HRV may be missing. Aera has not yet been tested on a real Oura or WHOOP account.

Do I need an Apple Watch to use Aera?

No. Workouts can come from other devices and apps, and the Apple Watch app is optional. Sleep needs some wearable, ring or sleep app that writes sleep to Apple Health, because an iPhone alone usually logs only time in bed.

Does Aera send my data anywhere?

No. Aera has no account, and your health numbers are worked out on your iPhone.
