What's New in Cairn
1.1.1
August 9, 2026
Improvements - The reflection banner on Path now looks at the past week - older moments quietly age out of the count - and tapping it takes you straight to the first moment waiting. - Reflection reminders now arrive only when recent moments are waiting for you. - On Apple Watch, a small icon appears on the home screen when moments are being kept on-device without iCloud sync. Fixes - Today's stone count, the Today and Yesterday headings on Path, and the Patterns week all move forward correctly when a new day begins. - Reminders arrive at the right time on daylight-saving days, and keep arriving even if the app hasn't been opened in a while. - Moments captured on Apple Watch are saved right away, even if you lower your wrist just after. - The cairn complication stays visible when the watch display dims. - The sync indicator no longer gets stuck on "Syncing". - Turning on reminders during onboarding now points you to Settings if notifications were declined earlier. - Deleting a moment from the reflection sheet closes cleanly.
