Fixes for iOS 27. CBP now syncs Time in Daylight from your Apple Watch and shows it in the Sunlight protocol.

Performance improvements and a refreshed training experience.

• Coaching is now your weekly letter

• Your health data now syncs in the background, without opening the app • Paused time no longer inflates your workout zone minutes • Timed and distance exercises now log in seconds or metres, not reps

Fixes a bug that could cause days of Apple Health data to go missing. If a sync ran while your phone was locked, the app could move past those days without uploading them and never come back to them. It now keeps its place and picks up anything it missed on the next sync. The "Last sync" time in Settings is also more accurate.

This update makes syncing and logging more dependable. - Your dashboard now refreshes on its own after every sync, so today's numbers show up without a pull-to-refresh. - The food log handles weak connections properly. If a day can't load you'll see a retry button instead of a blank form, and nothing you've already logged can be lost. - Been away from the app for a while? Your workouts and heart rate now catch up the moment you're back. Nothing gets skipped. - Stand hours are now measured correctly. Apple Health may ask once for permission to read Stand Hours: that's this fix. - The sync switch in Settings now truly pauses syncing until you turn it back on. - Smaller accuracy and reliability fixes throughout.
