Fit Rest: Sleep & Heart Rate

Body Battery, an expanded Heart tab, and daylight tracking - the biggest FitRest update yet. BODY BATTERY • Watch your energy reserve fill overnight and drain throughout the day. Recovery sets the ceiling, while activity and stress determine the pace. The card shows exactly where you recharged and where you burned energy. A DEEPER HEART TAB • Heart Signals highlights when a metric drifts from your personal baseline. Training Adaptation tracks HRV stability and resting heart rate trends. Cardio Fitness combines VO₂ max with your Fitness Age. Plus Time in Zones, Cardio Recovery, Blood Pressure trends, Heart Rhythm with ECG and AFib history, and Heart Rate Trends. MORE TRAINING ANALYSIS • Cardio Load, Activity Trend, Training Rhythm, When You Train, Workout Comparison, Effort vs. Recovery, Top Intensity, Personal Records, and your Athlete Profile - plus Monthly Recap and Your Year retrospectives. RICHER WORKOUT DETAILS • See splits, elevation gain, cadence, power, stroke count, pool lengths, SWOLF, cardio recovery, and even the weather you trained in. Route Replay is smoother, colors your path by speed, and exports as a shareable video in two styles. SLEEP, REBUILT AROUND YOUR BASELINES • Every sleep screen now compares last night to your normal instead of a generic chart, including your score breakdown, sleep architecture, HRV, blood oxygen, disruptions, respiratory rate, wrist temperature, and heart rate overlaid on your sleep stages. Sleep goals have also moved to a 24-hour dial you can drag. SUNLIGHT • Set a daily daylight goal, see exactly when you reached it, understand how your morning light aligns with your sleep, receive reminders, and use dedicated widgets. SMART INSIGHTS • One short, actionable insight at the top of your dashboard that changes throughout the day — and tells you why. A CALENDAR FOR YOUR SCORES • Pick any day from a monthly calendar, and the entire app follows it. Color the calendar by recovery, sleep, stress, exertion, steps, energy, sunlight, and more. WATCH AND WIDGETS • New watch complications and Smart Stack cards, plus Lock Screen widgets for Body Battery, Recovery, Sleep, Stress, Exertion, and Steps. MAKE IT YOURS • Choose your app icon, select which tab opens first, reorder and resize every section on every tab, and set your units once — they automatically sync to your watch through iCloud. ALSO • The Steps card now shows whether you're ahead of or behind your usual pace. • Rebuilt Achievements and Records. • Redesigned onboarding. • Skeleton loading and a much faster dashboard. • Translated into every language FitRest supports.
