How often watch data updates depends on internet availability and if the app is open:
- App is open with an internet connection: When the ForeFlight Watch app is opened and an active internet connection is available, the app automatically fetches updated data. If the app is left open, data is updated every five minutes or when the ForeFlight Watch app detects that you have traveled more than 2 nm, whichever occurs first.
- App is closed with an internet connection: When the app is not open, ForeFlight complications automatically update every fifteen minutes.
- Offline: If an internet connection is unavailable, data that was previously obtained is shown for up to one hour. After an hour without internet access, the fields are blanked.
