Your timer can do a lot more now:

• Adaptive HR can extend recovery until you reach your target heart rate and guide hard efforts with low and high alerts.
• Timer Music lets you choose a default song or set different music for individual intervals.
• Live Activities and updated Dynamic Island layouts keep compatible sessions visible and within reach.
• Home Screen widgets, Siri and Shortcuts make saved timers quicker to start and control.
• Gym Display gives you a clearer view on a large screen or mirrored TV.
• Share and import timers with a file or QR code, review completed sessions in workout history, and protect your setup with automatic iCloud backups.
• A configurable lap stopwatch is now available on iPhone. Countdown and Stopwatch have also arrived on Apple Watch.
• The refreshed design includes a new app icon and improvements to timer reliability, background alerts and heart-rate connections.
