Common questions
Why do I need to reconnect now that Fitbit moved to Google?
Fitbit data is now served through the Google Health API, and the old Fitbit web connection was turned off on 2 November 2026. Connections made through the old service do not carry over, so you sign in once with your Google account in Tandeo and approve access again.
How reliable is background sync on iOS?
With Lifetime, Tandeo asks iOS to sync in the background. iOS decides when that actually runs, based on battery, connectivity and how often you use the app, so timing is not guaranteed and can be delayed. You can always open Tandeo and sync manually.
Will I get duplicate data?
Tandeo keeps track of what it has already written in each direction so the same record is not copied back and forth. If another app also writes the same data to Apple Health, Apple Health combines sources using its own priority list, which you can change in the Health app under Data Sources & Access.
How do I get a refund or cancel?
Purchases and subscriptions are handled by Apple. Request a refund at reportaproblem.apple.com, and cancel a subscription in iOS Settings under your name, then Subscriptions, at least 24 hours before it renews. We cannot issue refunds ourselves, but we are happy to help if something goes wrong.
Can you see my health data?
Your health data is never sent to us: syncing happens on your device. Tandeo does send anonymous usage events and crash reports through Google Firebase, never containing health values, and you can turn this off in Settings under Share anonymous usage data. See the privacy policy for details.
Is Tandeo made by Google, Fitbit or Apple?
No. Tandeo is an independent app from Minima Apps Ltd and is not affiliated with or endorsed by Google, Fitbit or Apple.
Why is nothing syncing in the background?
Background sync is part of Pro and Lifetime. iOS decides when background work runs, and may delay or skip it if Low Power Mode is on, battery is low, Background App Refresh is off for Tandeo, or you rarely open the app. Open Tandeo and sync manually to catch up.
Why are steps or heart rate not syncing from Apple Health to Google Health?
Google Health does not accept steps or heart rate data from other apps. From Apple Health to Google Health, Tandeo syncs weight, body fat, workouts and sleep.
How do I disconnect Google Health?
Open Tandeo and choose Disconnect. You can also remove access at myaccount.google.com/connections.
How do I restore my purchase on a new device?
Sign in with the same Apple Account and use Restore Purchases in the app.
