Compatibility

Does mine work?

Penng does not integrate with each wearable brand one by one. On iPhone it reads Apple Health. On Android it reads Health Connect by Google. What arrives is the data types Penng reads, out of whatever your device chooses to write there.

Every answer, without the picker

The chooser above needs JavaScript. The same answers are listed here.

Apple Watch · via Apple Health

Apple Watch records heart rate, HRV, sleep and workouts. Penng reads all four.

What to do: In Setup, allow Penng to read Health. That is the whole step.

Series 6 and later also report blood oxygen. Live in-app heart rate and app-started workouts stay band-only.
Garmin (iPhone) · via Apple Health

Garmin records your sleep, heart rate and workouts. Penng reads them once Garmin is sharing.

What to do: Open Garmin Connect, turn on its Apple Health sharing, then allow Penng to read Health.

Garmin chooses which metrics it writes to Apple Health. Check Garmin Connect settings if something is missing.
Garmin (Android) · via Health Connect by Google

Garmin records your sleep, heart rate and workouts. Penng reads them once Garmin is sharing.

What to do: Open Garmin Connect, turn on its Health Connect sharing, then allow Penng to read it.

Blood oxygen availability through Health Connect varies by device.
Oura Ring (iPhone) · via Apple Health

Oura records your sleep, heart rate and HRV. Penng reads all three.

What to do: In the Oura app turn on Apple Health sharing, then allow Penng to read Health.

Oura does not record workouts the way a watch does, so training data will be thinner.
Fitbit (Android) · via Health Connect by Google

Fitbit records your sleep, heart rate and steps. Penng reads them once Fitbit is sharing.

What to do: In the Fitbit app turn on Health Connect sharing, then allow Penng to read it.

Fitbit's Health Connect support depends on your app version and device.
Samsung Galaxy Watch · via Health Connect by Google

Galaxy Watch records your sleep, heart rate and workouts. Penng reads them.

What to do: Allow Samsung Health to share with Health Connect, then allow Penng to read it.
Just my iPhone, no watch · via Apple Health

Your phone counts steps and records some workouts, and food logging works from day one. Sleep and recovery need a wrist sensor.

What to do: Allow Penng to read Health, then log your first meal. Add a band later if you want recovery and sleep.

Without a wrist sensor there is no overnight heart rate, so recovery and sleep scores cannot be produced. A band fixes that.
Just my Android phone, no watch · via Health Connect by Google

Your phone counts steps and records some workouts, and food logging works from day one. Sleep and recovery need a wrist sensor.

What to do: Allow Penng to read Health Connect, then log your first meal. Add a band later if you want recovery and sleep.

Without a wrist sensor there is no overnight heart rate, so recovery and sleep scores cannot be produced. A band fixes that.
No wearable at all · via Penng band

Food logging, plans and habits work with no wearable at all. Sleep and recovery need something on your wrist.

What to do: Start with the app today. Add a Penng band when you want sleep and recovery too.

Penng reads what your device's own app shares with your phone. We have not tested every model one by one, so check your first morning's numbers.

Check before you pay

Will Penng work with what I already wear?

Penng does not talk to each brand directly. On iPhone it reads Apple Health, on Android it reads Health Connect by Google. Whether yours works depends on what it writes there, and its maker decides that, not Penng.

What each connection can and cannot do.

These rows come from the app’s own capability flags, not a marketing summary. Where a row says it varies, the flag itself is a plain yes or no for the route, and the honest answer still depends on the device you own. Individual watch and ring models have not been tested one by one.

Capability	Penng BandiPhone and Android	Apple HealthiPhone	Health Connect by GoogleAndroid
Live heart rate in the appA live heart-rate stream while you train. Only the Penng band streams over Bluetooth.	Yes supported	No not available	No not available

HRVMost modern watches expose HRV. Some older or budget devices do not. Without it, recovery falls back to 60 per cent your sleep score and 40 per cent how close your resting heart rate is to your own measured baseline. Until Penng has measured that baseline from your own nights, it shows no recovery score rather than a guess.	Yes supported	Yes supported	Varies depends on your device
Blood oxygen (SpO2)Apple Watch Series 6 and later report SpO2. On Android it varies widely by device.	Yes supported	Yes supported	Varies depends on your device
Blood pressureThe band takes a reading. Very few consumer wearables measure it at all, so the flag for imported sources is off; if yours does measure it and writes it to the health store, that is a case this row does not cover.	Yes supported	Varies depends on your device	Varies depends on your device
Data arrives without waiting for a syncImported sources are pulled from the health store on a sync rather than pushed as they happen, so figures can lag behind the watch. It does not mean the band senses continuously; it samples.	Yes supported	Varies depends on your device	Varies depends on your device

The same either way

Most of Penng does not care what you wear.

Food logging by photo, barcode or text

Photograph a meal, get an editable estimate, adjust the portion and log it.

Sleep, recovery and strain scores

Calculated by Penng, each from its own inputs. Sleep: hours against your need, how steady your sleep midpoint is, and time asleep against time in bed. Strain: heart rate through the day, workouts and steps. Recovery: HRV and resting heart rate against your own baselines, plus your sleep score.
