Availability: iPhone · iPad · Mac · Free. Checked for app version: 1.0.0.
Outcome
Local use is the default; after sign-in, you can opt into a privacy-reduced collection sync between iPhone, iPad and Mac.
How to do it
- Keep using MODE 1090 without an account when one local collection is enough.
- To sync, sign in to the same verified account on each supported Flutter device.
- Open Account settings and enable collection sync.
- Wait for the status to report a successful synchronization before switching devices.
- Resolve duplicate or offline states from the same Account page and retry when the connection is stable.
Good to know
- Exact location and sensor evidence are not part of the compact synchronized record.
- Apple Watch and Apple TV do not contain the account or collection-sync interface.
- Create a JSON backup before clearing local or synchronized data.
If the result looks different, open Settings > Help and send the visible status together with device, operating system and app version.
