Troubleshooting
Step-by-step fixes for the most common sync issues. For full setup instructions see the Health Sync guide.
Sleep isn't tracking
BlazeFiit reads your Android sleep from Health Connect. It can only show sleep that (1) something recorded, (2) that source shared into Health Connect, and (3) BlazeFiit has permission to read. Work through these in order — most people are fixed by step 5.
1. Make sure something is tracking your sleep
Best is a watch or fitness band worn to bed. No wearable? Some phones can still track sleep on their own (a little less accurately) — for example Samsung Health sleep on Samsung phones, Bedtime mode on Pixel, or a sleep app. If nothing is set up to record your sleep, that’s the reason: there’s no sleep data for BlazeFiit to read yet.
2. Update BlazeFiit & check for the shortcut
Update to the latest version in the Play Store and open the app. If you see a “Sleep permission is off” box in Settings, tap Allow sleep — that fixes it for most people. Then jump to step 6.
3. Confirm sleep in your source app first
Open your watch app (Samsung Health, Fitbit, Mi Fitness…) or your phone’s sleep app and check that last night’s sleep actually shows there. If it doesn’t, BlazeFiit can’t read it either — get sleep showing in that app first (wear the watch to bed / turn on the phone’s sleep tracking).
4. Share Sleep to Health Connect
Open Samsung Health → Settings → Health Connect (or your band’s app → Health Connect / Connected services) and make sure Sleep is turned ON. It’s a separate switch from Steps — steps-on / sleep-off is a common default.
5. Let BlazeFiit read Sleep
Open the Health Connect app → App permissions → BlazeFiit → turn on Sleep.
6. Refresh
Open BlazeFiit, go to the dashboard, and pull down to refresh. Your last several nights should appear.
Fitbit or Pixel Watch? Read this.
Fitbit and Pixel devices often sync to Google’s cloud instead of Health Connect, so the steps above may not reach your sleep. If it’s still missing, open BlazeFiit → Settings → Health integrations → Connect Google Health and sign in with the Google account your device uses. Fitbit users must first move their Fitbit account to a Google Account.
This is only for Fitbit and Pixel. Samsung, Garmin, Xiaomi, Amazfit and other watches sync through Health Connect (the steps above) — don’t connect Google Health for those, it won’t help and can cause confusion.
Still nothing? Health Connect can’t pull sleep from more than about 30 days before you granted permission, so deep history won’t backfill — but new nights will. If today’s sleep is in your watch app, shared, and permitted and it’s still missing, email support@blazefiit.com with your phone model and watch/band brand.
Sleep isn't tracking
On iPhone, BlazeFiit reads your sleep from Apple Health. As with Android, it can only show sleep that something recorded and that BlazeFiit has permission to read.
1. Make sure something records your sleep
An Apple Watch worn to bed is the most reliable. An iPhone on its own can set a Sleep Schedule (Health app → Browse → Sleep) but only estimates limited data without a watch. Other wearables (Oura, Whoop, Garmin…) work if their app is set to write sleep into Apple Health.
2. Confirm sleep in the Health app first
Open the Health app → Browse → Sleep and check that last night shows. If it’s not there, BlazeFiit can’t read it — fix the source first.
3. Let BlazeFiit read Sleep
Go to iPhone Settings → Health → Data Access & Devices → BlazeFiit and make sure Sleep is turned on (it’s a separate switch from Steps — it’s easy to grant one and not the other).
4. Refresh
Open BlazeFiit and pull down to refresh on the dashboard.
Fitbit on an iPhone? Read this.
Fitbit doesn’t write to Apple Health on its own, so pick one of these:
Option 1 — a bridge app. Use an app that copies your Fitbit data into Apple Health; then it flows into BlazeFiit like any other Apple Health data and everything above applies. A simple one that works is Power Sync for Fitbit (third-party app — we’re not affiliated; just allow it to write Sleep to Apple Health).
Option 2 — Google Health. In BlazeFiit go to Settings → Health integrations → Connect Google Health, signed in with the Google account linked to your Fitbit. You must first move your Fitbit account to a Google Account.
My steps show 0
- Android: make sure your health app (Samsung Health, Fitbit, etc.) is sharing Steps to Health Connect, and that BlazeFiit has the Steps permission (Health Connect → App permissions → BlazeFiit).
- iPhone: Settings → Health → Data Access & Devices → BlazeFiit → enable Steps.
- Confirm today’s steps exist in your health app first — if they’re not there, there’s nothing to read.
- Open BlazeFiit and pull down to refresh on the dashboard.
- On some Android phones, exclude BlazeFiit and Health Connect from battery optimization so background sync isn’t killed.
My numbers don't match my watch or another app
On Android, BlazeFiit shows the Health Connect total, which keeps one source per time period rather than adding every app together (so a watch + phone don’t double-count). If a different app shows a higher number, it’s usually because that app ranks lower in your Health Connect priority list, or isn’t writing its full data into Health Connect.
To choose which app BlazeFiit follows: open Health Connect → Data sources and priority → drag the app you trust to the top. Full explanation and screenshots are in the Health Sync guide.
