How do I change the week-numbering rule?
On iPhone or iPad, open Settings in Week Number and choose ISO 8601 or Sunday-based. On Apple Watch, open the gear button and choose the same setting.
Why does a widget show an older setting?
Open Week Number once after changing the rule. If needed, remove and add the widget again so the system refreshes its timeline.
How does Apple Watch sync work?
The selected rule is sent directly between your paired iPhone and Apple Watch when they are reachable. Week Number does not use a server.
Does Week Number collect personal data?
No. Read the full privacy policy for details.
