Power Sync

What Power Sync does

Your Fitbit tracker or Pixel Watch records your steps, sleep and heart rate in your Google Health account. Power Sync reads that data, with your permission, and writes it into Apple Health on your iPhone, so it shows up next to the rest of your health data and in the apps you connect to Apple Health.

• Activity: steps, walking and running distance, floors climbed, active and resting energy, workouts.
• Heart and vitals: heart rate, resting heart rate, heart rate variability, blood oxygen (SpO2), breathing rate, cardio fitness (VO2 max).
• Body: weight, body fat, body mass index and lean body mass.
• Sleep: sleep sessions with light, deep and REM stages.
• Nutrition: water and calories you log.

You choose which data types to sync, and you start each sync yourself. Syncing a time range (a week, a month, a year or your full history) is part of Power Sync Pro; syncing today's steps is free.

How Power Sync uses your Google Health data

Power Sync connects to your Google Health account through Google's official sign-in and the Google Health API. It asks only for read-only access to these categories, and only to copy the data into Apple Health:

Permission	Why Power Sync needs it
Activity and fitness	Steps, distance, floors, active energy, calories, cardio fitness and workouts for Apple Health.
Health metrics and measurements	Heart rate, resting heart rate, heart rate variability, SpO2, breathing rate, weight and body fat for Apple Health.
Sleep	Sleep sessions and sleep stages for Apple Health.
Nutrition	Logged water and food calories for Apple Health.

The data goes straight from Google to the Power Sync app on your iPhone and from there into Apple Health. Power Sync does not upload your health data to its own servers, does not sell it, and does not use it for advertising. Power Sync's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. Details are in our Privacy Policy.

You can disconnect at any time from Settings in the app. Disconnecting revokes Power Sync's access to your Google Health data. You can also remove access from your Google Account.

Before you connect

Google Health data is available to Power Sync once your Fitbit data lives in a Google Account. Open the Google Health app on your phone and sign in with your Google Account first (if you still use a Fitbit account, the app will offer to move it to your Google Account). Then open Power Sync and connect with the same Google Account.
