What's new

Version 7.15.0 · 5 Oct 2026 · 4 days ago

Fasting, hands-free. This update makes Zero easier to reach when you're on the go, with enhanced Siri support for fasting and a quicker way into meal logging. • Fasting with Siri: Start, end, or check on your fast just by asking — try "Start my fast in Zero." Zero now works with Siri automatically, with no setup needed, and is updated for the new Siri in iOS 27. • Quicker Meal Logging: Add the new Log Meal control to your Lock Screen, Control Center, or Action button to jump straight into logging a meal. Requires iOS 18 or later. • Bug Fixes: Fixed an issue that could prevent logging your weight on iOS 27, and improved compatibility with the latest version of iOS.
