eFit reads your activity from Google Health. Any watch, band, ring, scale, or phone that can send its data to Google Health will count toward your course. This article lists the devices students use most, tells you which phone each one needs, and shows how to connect it.
Prefer to be walked through it? The Tracker Connection Wizard asks which phone and tracker you have, then gives you the exact connection path, setup steps, and a verification checklist for your combination.
How your tracker reaches eFit
Your tracker never talks to eFit directly. Data travels along one of two chains, depending on the phone you carry.
| Your phone | The chain your data follows |
|---|---|
| Android | Tracker app (Garmin Connect, Samsung Health, Zepp, and so on) to Android Health Connect to Google Health to eFit |
| iPhone | Tracker app to Apple Health to the free Google Health app to eFit |
Because every chain ends at Google Health, you only connect eFit once. Add or replace a tracker later and it keeps working with no change on the eFit side.
Compatible devices
| Device | Android | iPhone | What you need to know |
|---|---|---|---|
| Fitbit devices | Yes | Yes | Fitbit is a Google product, and the Fitbit app became the Google Health app in May 2026. Pair and sync the watch in the Google Health app itself, and open it every day or two so the watch uploads. |
| Google Pixel Watch | Yes | Yes | Sends steps, heart rate, and Active Zone Minutes straight to the Google Health app. |
| Apple Watch | No | Yes | Connect Google Health to Apple Health on your iPhone or iPad. Steps, sleep stages, exercise, heart rate, blood oxygen, and breathing rate come through. Apple's exercise minutes and stand hours do not. |
| Samsung Galaxy Watch | Yes | Older models | On Android, through Health Connect. In the Samsung Health app settings you must turn on consent to health data processing, otherwise nothing leaves the watch. Steps, sleep, exercise, heart rate, blood oxygen, and VO2 max come through. Galaxy Watch4 and newer and the Galaxy Ring pair with Android only; older models such as Galaxy Watch3, Watch Active2, Galaxy Fit, and the Gear series can pair with an iPhone through the legacy Samsung watch app and share data to Apple Health. |
| Garmin watches and trackers | Yes | Yes | Android uses Health Connect, iPhone uses Apple Health. Open the Garmin Connect app regularly so the watch uploads on time. Heart rate variability, breathing rate, blood oxygen, and VO2 max stay in Garmin Connect. |
| Oura Ring | Yes | Yes | Health Connect on Android, Apple Health on iPhone. Sends steps, sleep, exercise summaries, heart rate, and heart rate variability. Resting heart rate, breathing rate, blood oxygen, skin temperature, and VO2 max stay in the Oura app. |
| Whoop | Yes | Partial | On Android, through Health Connect: exercise heart rate, steps, calories, sleep stages, resting heart rate, and breathing rate. On iPhone, the WHOOP app writes sleep, workouts, workout heart rate, active energy, respiratory rate, and blood oxygen to Apple Health, and it never writes steps, so carry the iPhone and let it count steps. |
| Zepp (Amazfit watches and trackers) | Yes | Yes | Health Connect on Android, Apple Health on iPhone. One of the fuller integrations: steps, sleep, exercise with maps, heart rate, breathing rate, and VO2 max. |
| Mi Fitness (Xiaomi watches and trackers) | Yes | Yes | Health Connect on Android, Apple Health on iPhone (in Mi Fitness: Profile, then Third-party data, then Health). Sends steps, sleep stages, exercise heart rate, exercise maps, and weight. |
| Withings scales and watches | Yes | Yes | Health Connect on Android, Apple Health on iPhone. Blood pressure readings are not supported in Google Health yet. |
| Your phone by itself | Yes | Yes | You can pass the activity portion of the course with no wearable at all. An Android phone counts steps with its built-in sensor, and an iPhone counts them in Apple Health. Carry the phone with you while you walk. |
Other brands work too as long as their app can write to Health Connect on Android or Apple Health on iPhone. Check your tracker app's settings for a Health Connect or Apple Health option.
Apps that also feed eFit
- MyFitnessPal sends nutrition, hydration, and exercise. Connect it through Health Connect, through Apple Health, or straight from the MyFitnessPal app under Apps & Devices. Using more than one of those routes at a time can log a meal twice.
- Strava now receives activities from Google Health going forward. Activities recorded in Strava before you connected will not travel back into Google Health, so keep your watch or phone as the source of truth for your eFit activity.
- Samsung Health and other phone apps reach eFit the same way, by writing to Health Connect.
What eFit reads from all of this
- Steps, for your daily step count
- Active Zone Minutes (AZM), the minutes of moderate and vigorous activity your weekly grade is built on
- Heart rate, when your device records it
- Nutrition, when a connected app logs your meals
Devices differ in how much they share. If your tracker sends heart rate during workouts, your Active Zone Minutes will be more accurate. A step-only band still earns credit through steps. See Understanding Your Weekly Activity Grade for how the numbers become a grade.
Connect your tracker
- Get your tracker into Google Health first. On Android, follow Connect on Android With Health Connect. On iPhone, follow Connect eFit on an iPhone.
- Open Sync Tracker in eFit. Log in, go to your Dashboard, and select Sync Tracker. Direct link: /dashboard/sync.php.
- Select "Connect with Google Health" and sign in with the Google account your fitness data lives in.
- Approve every permission box so eFit can read your steps and active minutes. Your activity then syncs automatically each night.

Check which devices and apps are connected
To see everything currently feeding your Google Health account:
- Open the Google Health app on your phone.
- Select the menu at the top left and choose Connections.
- Choose Partner apps or Apps and services.
- Everything under Connected is currently sharing data. You can browse the same screen to add another app or device.
The Google Health app runs on Android and iOS. It does not install on the watch or tracker itself, so keep it on the phone you carry.
If a device is not compatible
A tracker that has no companion app, or whose app cannot write to Health Connect or Apple Health, cannot reach eFit. In that case, carry your phone during activity and let the phone count your steps, or use a supported tracker from the table above. Contact support through this helpdesk if you are unsure about a specific model.
Your tracker is connected but nothing appears
- Your Activity Shows on Your Phone but Not in eFit
- Synced to Google Health but No New Activity in eFit
- Disconnect or Change Your Tracker
