- Onboarding Health permission moment fixes

Apple Watch companion is here. - Today — readiness, recovery, and weekly Zone 2 at a glance - Effort — live heart rate vs your Zone 2 band while you train in any workout app - Overnight — HRV, resting heart rate, and sleep vs your personal baselines - Complications for readiness and Zone 2 week progress - Syncs from iPhone; private and on-device — free for everyone, no Pro required Open the Longevity Arc app on iPhone once so your Watch can sync, then wear it for coaching on the wrist.

Introducing Protocols - your personal longevity lab. Run a structured, time-boxed experiment and see whether it actually moved your numbers: Four protocols to choose from - Zone 2 Block, Sleep Regularity Reset, HRV Recovery Week, and Strength Ramp. Follow your journey - a milestone timeline, momentum stats, and live "moving so far" signal changes while your protocol runs. See what changed - when a protocol finishes, we automatically compare your baseline to your after and explain it in plain language. No AI or newer iPhone required. A gentle daily check-in - one evening reminder while a protocol is active. A question, not a nag. Plus a faster app that loads your data more quickly in the morning, and various fixes and polish.

• Outdoor runs and other higher-intensity workouts now count toward your Zone 2 minutes — we measure the time your heart rate actually spent in the Zone 2 range, instead of judging the whole workout by its average. • Works with any heart-rate source — Apple Watch, Garmin, Zepp, Polar and more — all handled the same way. • Updated the Zone 2 target range to the one used for cardiovascular and longevity benefit. • Clearer labels: the dashboard ring shows "this week," while the signal detail now shows your rolling "last 7 days," so the two numbers are no longer mistaken for the same thing.

Zone 2 Progress Ring — track your weekly Zone 2 cardio minutes against your goal, right on the dashboard Workout Recovery guidance — a clear recommendation on whether to push hard, ease off, or rest, based on your HRV and resting heart rate Strength Training signal — your weekly strength sessions now count toward your biological age Personal pattern insights — discover how your own sleep, activity, and recovery connect (e.g. "Your HRV is 18% lower after under 7h of sleep") More reliable tracking for Garmin, Zepp, Whoop, and Oura — better Zone 2, strength, recovery, and sleep accuracy for non-Apple-Watch wearables

Three new longevity signals from Apple Watch: • Blood Oxygen (SpO₂) - overnight nadir tracking • Cardio Recovery (HRR) - 1-minute heart rate drop after workouts All three are included in your longevity score, signal list and detail views

Biological Age 2.0 - your most comprehensive longevity score yet. • Biological Age model - a multi-signal score across Cardiovascular, Recovery, and Metabolic dimensions, showing how your biology compares to your chronological age • Cardio Recovery (HRR) - heart rate recovery after workouts, a leading marker of autonomic fitness and cardiovascular health • Blood Oxygen (SpO₂) - overnight oxygen saturation nadir, with alerts for persistent dips linked to sleep apnea • Wrist Temperature - nightly deviation from your personal baseline, an early indicator of illness and physiological stress • Driver ranking - see exactly which signals are saving or adding years to your biological age, with one tap to the full signal detail • Monthly bio-age trend - track your biological age trajectory over the past four weeks • Personal baseline bands - signal detail charts now show your mean ± 1 SD band so you can see when a reading is truly unusual for you

Daily Readiness Score - a new card on your dashboard tells you whether to train hard, keep it Zone 2, or prioritize recovery today, based on your HRV, sleep, and resting heart rate. Automatic alerts flag anomalies like an RHR spike or declining HRV before they affect your Arc Score. Explore more insights on demand - Pro users can now tap "Try another lens" to cycle through all 12 insight templates instead of waiting for tomorrow's rotation.

- 2 new longevity signals: overnight respiratory rate, blood pressure - Sleep now shows deep % and REM % when Apple Watch stage data is available - VO₂max now shows Measured vs Estimated badge; defaults to Longevity Optimized benchmark - Dashboard signals are now customisable — drag to reorder, toggle to show or hide - Widget signal picker — choose which 5 signals appear in the large widget

widget sync issues

Smarter source selection - Apple Watch wins when data is complete; more-covered wearable wins otherwise

Widget refreshes fixes

Widget refreshes once daily at 7 AM - shows yesterday's data with a tap-to-update chip

- Widget freshness indicator - Your home screen widget now shows how long ago your data was last synced. If it's been more than 4 hours, a refresh chip appears - tap it to open the app and sync instantly. - Smarter HRV for Oura, Garmin, Whoop, and more - Third-party wearables report RMSSD rather than SDNN, and the app now detects this automatically. Your HRV signal is now scored against the correct reference ranges for your device, with no setup required.

Signals like VO₂max and gait speed now use only completed days of data, so a mid-afternoon check no longer shows a deflated score from half a day of steps.

- Algorithm tuning - stricter scoring to better reflect real longevity benchmarks - VO₂max benchmark mode: General Population vs Longevity Optimized (top 25%)
