Jet lag plans Add a trip, or let Better find your flights in your calendar if you allow it, and get a day-by-day plan for the new time zone. Your Better Sleep reminders move to local time automatically. More reliable HRV Better now calculates HRV from the short recordings Apple Watch takes overnight, so more nights get a reading. If there isn’t one, it uses Apple Health’s reading instead. Faster sync New nights from Apple Health show up sooner after you wake up and open the app. A refreshed look Updated design and smoother screens across the app, plus improvements to Settings. Bug fixes and stability improvements

A fresh new look. Better has been redesigned with a light, warm style, new typography and cleaner cards, so your sleep data is easier to read at a glance. Clearer sleep stages. Deep, REM, Core and Awake now each have their own colour, so they're easier to tell apart in your sleep details. Apple's Liquid Glass tab bar. Navigation uses the native iOS 26 tab bar. Faster and smoother. Trends opens faster, there are fewer full re-syncs after installing, and scrolling on Home is smoother. Account deletion is more thorough. Deleting your account from Settings → Account now also revokes Sign in with Apple. Bug fixes and reliability improvements.

Updated the sleep stages UI with a clearer timeline, improved stage details, and an easier way to explore your night’s sleep.

A new look for the app icon, and a much better night. Sleep Mode, rebuilt. A guided 4-7-8 breathing exercise that slows your heart rate before sleep, and a pink noise bed that fades in and out instead of cutting. Now reachable any time of day, not just after 8pm. A clearer Sleep home. Restorative sleep — deep plus REM — leads the screen, every card reads in the same order, and each figure shows both its share of the night and the actual time. Charts you can read. Trends now labels its axis, shades your typical range behind the marks, and stays quiet when there is nothing meaningful to say. Fixes: • The app could refuse to open with the message "Couldn't open Better." It now opens while the phone is locked, as it should. • Stored sleep history could be lost after restoring to a new device, taking your sign-in with it. • A correctly updated database could report itself as newer than the app and show a downgrade screen. • Nights are reaching the community boards again.

Added AI Sleep Reports, improved. Your personalized AI insights are more visible on the dashboard and the underlying report quality has been refined

We added a new Community tab so you can compare your sleep with friends, plus AI-enhanced sleep reviews that explain your night in simple language and suggest ways to improve. You can now view morning briefings, full nightly reports, and weekly/monthly AI Reviews directly from the app. This update also improves dashboard layout, Community reliability, privacy controls, and AI report handling.

We redesigned the Sleep tab to make your night easier to understand at a glance. • Clearer "what changed" insights — Your dashboard now highlights the two most meaningful changes in last night's sleep versus your usual, with color-coded improvements and declines. • Simpler Sleep Stages — Each stage (Awake, Light, Deep, REM) is now color-matched to the chart above for faster reading, with a cleaner, less cluttered layout. • Tap to compare — Tap Total, Bedtime, or Wake to instantly see how they compare to your typical night. New indicator bars show whether you slept more or less than usual at a glance. • Smarter sleep score — Tap and hold the score ring to see the full breakdown of how it's calculated. • At-a-glance data source — A new sync indicator in the top corner shows where your data comes from and when it last updated. • Smoother startup — Fixed an issue where the app could briefly show a "Connect Apple Health" message even when you were already connected. You'll now see a gentle syncing animation while your latest sleep loads.

Chronotype Insights — Discover your natural sleep rhythm. The app now learns your personal chronotype and surfaces plain-language insights about when your body is wired to sleep and wake. Faster, Smarter Sleep Dashboard — Your nightly dashboard now loads instantly and reflects a fuller picture of "your usual sleep" for more accurate comparisons. Sharper Sleep Analysis — Improved biomarker baselines and sleep-stage detection mean more reliable quality scores and trends over time. Refined Protocol Tracking — A cleaner Protocol Formula experience makes it easier to see how your supplements and habits affect your sleep. Performance & Reliability — Background sync is more dependable, and we've squashed bugs across sleep, trends, and settings for a smoother experience. Thanks for using Better. Keep tracking — your data is getting smarter every night.

Protocol Formula Tracking — full replacement of the old Protocol tab with ProtocolFormulaVersion/ProtocolNightLog/ProtocolBaselineSnapshot models, 5 new services (baseline freeze, per-version rollups, impact analysis, catalog management, insights generation), and 9 new screens (onboarding, home, timeline, all-metrics, version dive, edit log, formula setup) Red Light Filter — RedLightFilterService (Shortcut-based system tint toggle) + in-app red overlay inside Sleep Mode + 3-step setup wizard in Settings

Sleep Mode A new wind-down experience to help you prepare for bed. Set a bedtime schedule, follow a guided breathing exercise, and optionally activate a full-screen blackout to reduce stimulation before sleep. Bedtime reminders are delivered as local notifications. Chronotype Insights Better now analyzes your rolling sleep timing to determine your chronotype (Early, Intermediate, or Late) and surfaces it in the Trends tab. You'll also see alerts when your chronotype appears to be shifting. Sleep Continuity Score A new card on the Sleep dashboard shows how consolidated your sleep was — tracking your longest restorative block, wake-after-sleep-onset (WASO), and fragmentation index alongside your existing quality score. Notification Preferences You can now choose which types of alerts trigger notifications. Each alert category has its own opt-in toggle in Settings → Notifications. Research Export Improvements Nightly CSV exports now include chronotype bucket, continuity score, and longest restorative block columns for deeper personal research.
