Google Health to Apple Health · iPhone

FitSend moves your Fitbit data into Apple Health. One way. No guesswork.

How it works

Set up once. Sync whenever you want.

Choose the supported data you want. FitSend securely moves it from Google Health to the Health app, then lets you follow it on your iPhone. Nothing is sent back to Google.

  1. Connect Google Health

    Sign in with Google and approve read-only access. That connection is your FitSend sign-in, so there is no separate account to create.

  2. Choose what syncs

    Pick from the supported data types, then allow FitSend to write the matching types in the Health app. Nothing else moves.

  3. Sync

    Tap Sync Latest and follow progress while FitSend works. With PRO, FitSend also syncs in the background when iOS allows.

  4. Follow your day

    Daily summaries, sleep details, charts, and trends. They are calculated on your iPhone and never uploaded.

FitSend shows sync progress and recent status. New readings can take time to appear when a source or iOS background delivery is delayed.

Built on exactness

Sync you don’t have to babysit.

A health total is only worth keeping if you can trust it. So FitSend is strict about what it writes, and says so plainly when it can’t write something.

  • Built to prevent duplicates

    Sync again without stacking another copy of the same measurement. FitSend checks what it already added before writing to the Health app.

  • Corrections follow

    When Google Health revises a supported reading, FitSend can replace its earlier copy instead of stacking another one. Deletions affect only records FitSend wrote.

  • Gaps stay gaps

    If the source has no data for an hour, the Health app shows no data for that hour. FitSend never estimates, backfills with guesses, or inflates totals.

  • Honest about limits

    Some Fitbit numbers have no true equivalent in the Health app. Active Zone Minutes are one: they are not the same thing as Exercise minutes, so FitSend reports them as unsupported instead of squeezing them into the wrong field.

What syncs

Eighteen data types, five families.

You choose which ones move. Each keeps its original timing, and nothing syncs without your permission for that category.

  • Activity

    Steps and energy arrive as timed intervals through the day, never as one made-up daily total. Workouts keep their type, duration, and timing.

    • Steps
    • Workouts
    • Active energy
    • Resting energy
    • Floors

  • Heart & fitness

    Heart rate is written at the moment each reading was taken. Resting heart rate, compatible HRV, and VO₂ max come along when the source has them.

    • Heart rate
    • Resting heart rate
    • HRV
    • VO₂ max

  • Sleep & breathing

    Each night arrives as a full session with its stages intact, plus blood oxygen and respiratory rate where they were recorded.

    • Sleep & stages
    • Blood oxygen
    • Respiratory rate

  • Body

    Weigh-ins and body measurements, so you never have to re-enter them by hand.

    • Weight
    • Body fat
    • Height
    • Body temperature

  • More health records

    Logged glucose readings and water intake, in their original units and timing.

    • Blood glucose
    • Water intake

Availability can vary by source and app version. FitSend shows the current list before you connect.

Privacy

Your measurements land on your iPhone. Not on our servers.

Read the privacy policy

  • No name or email required

    Your FitSend account uses a random identifier. We never ask for your name or email.

  • No cloud health history

    Measurements move through FitSend during sync and land on your iPhone. We remember sync progress, not measurement values.

  • No ads. No trackers.

    No advertising, no analytics SDKs, no data brokers, no selling. Your health data is never used for pricing, profiling, or “partners.”

  • Leave completely, any time

    Disconnect Google or delete your account in the app. Primary data is gone within 24 hours, backups within 30 days, and you decide whether the Health app copies stay.

Plans

Free to use. PRO when you want it automatic.

Free

Everyone

Sync by hand, track every day, keep every privacy control.

  • Sync supported Google Health data whenever you want
  • Bring in your latest day of supported data
  • Follow daily summaries and trends from the Health app
  • Choose permissions, export your account data, disconnect, or delete

PRO

Subscription

Everything in Free, plus background sync and your full available history.

  • Automatic background sync for supported Google Health data
  • Full available history for supported categories
  • Monthly or annual billing with the same PRO features
  • The same privacy protections as Free

Prices are shown in the App Store before you buy, and Apple handles all billing; FitSend never sees your payment details. Automatic sync is best-effort: iOS decides when background work runs, and FitSend catches up every time you open the app.

Questions

Fair questions, straight answers.

Something else on your mind? Support has more, and a person reads every message.

Does FitSend work with Fitbit and Fitbit Air?

Yes, with one thing to know: FitSend doesn’t talk to the tracker itself. Your Fitbit syncs to the Fitbit app as usual, that data becomes available through Google Health, and FitSend picks it up from there. Keep the Fitbit app installed and syncing.

Does anything get sent back to Google or Fitbit?

No. FitSend’s access to Google Health is read-only, and it writes only to the Health app on your iPhone. Nothing FitSend does changes your Google or Fitbit data.

How much history can I bring over?

Free syncs your latest day of supported data, as often as you like. PRO imports all available history for the data types you select, and resumes from saved progress if an import is interrupted.

Why do you call automatic sync “best-effort”?

Because that’s the truth on iOS. Apple decides when apps may run in the background, so automatic sync usually lands quickly but is never guaranteed to the minute. Opening FitSend checks for updates and catches up when Google Health and iOS are available.

Will my totals in the Health app get inflated or doubled?

FitSend uses stable record identities to prevent repeat syncs from creating another copy. Supported source corrections replace the FitSend copy, and source deletions remove only records FitSend created. Data from other apps is never touched.

What actually happens if I delete my account?

Deletion runs from inside the app, and it’s real: your account, Google connection, and sync state are erased from primary systems within 24 hours, and from encrypted backups within 30 days. You choose whether the data already written to the Health app stays on your iPhone or goes with it. Full details here.

Is FitSend a medical app?

No. FitSend moves your fitness data and shows wellness insights. It does not diagnose, treat, or alert, and it’s not a substitute for medical advice or devices.
