Stress: HRV Tracker

Personal Baseline for Watch

Free · In‑App Purchases

Read stress against your own HRV and resting heart rate. Alerts only for meaningful changes. Works on Apple Watch. In closed beta — free redeem codes available. Understand your body's stress — instead of waiting until it gives out. Stress is a stress monitor for Apple Watch and iPhone. It reads your HRV (heart rate variability), RHR (resting heart rate), sleep and activity, compares them with your own baseline and answers one question daily: keep pushing, or ease off? ◎ Stress read against your own baseline - Four plain levels: Fully Charged · Doing Fine · A Bit Tired · Feeling Rough - No generic "normal range": the app learns your own HRV and resting heart rate, day and night apart - Under 7 days it says the baseline is only indicative; from 28 days it's stable - Every number comes with a one-line takeaway ◎ Stress rising? Ease it on the spot - Relaxing 4-4, Deep 4-7-8, Box 4-4-4-4, Snore Relief 5-6 — 1, 3 or 5 minutes, matched to your stress right now - Note your mood after; the time counts as Mindful Minutes in the Health app ◎ Your night on one page - Sleep score, stage timeline, naps counted separately - Overnight HRV, resting heart rate and wrist temperature - Compared with your usual bedtime, so you spot when the routine slipped ◎ Mood, water and daylight — no extra apps - Mood check-ins built on State of Mind in the Health app, plus your mood pattern on higher-stress days - One-tap water logging into the Health app, with daily goal and weekly trend - Steps, active energy, workout routes with heart rate zones, time in daylight ◎ Trends that read like a weekly report - Week, month and year: your stress patterns in plain words, your best days, and when stress quietly climbs - HRV, resting heart rate, sleep, activity, water, daylight and breathing side by side ◎ Works on its own on Apple Watch - Complications: stress, HRV, heart rate, steps, water, active energy - Browse stress and trends on your wrist, and log water there - If a fresh HRV reading points to higher stress, your watch tells you ◎ Useful without opening the app - Siri and Shortcuts: check stress, log water, start breathing, log mood - Control Center: start breathing or log water in one tap - Widgets on Home and Lock Screen: stress, HRV, heart rate, steps, water, energy, breathing - Split view on iPad; 11 interface languages ◎ What we believe Life is full of numbers already; one more opaque stress number doesn't make anyone feel lighter. So every metric comes with a takeaway: read "A Bit Tired" and you know what's next — an hour more sleep, three deep breaths before the meeting, a walk instead of the hard weekend session. No alarms, no lectures. ◎ Your data is yours - Health data is read and processed on your device only, never uploaded, no account needed - We read only the data types you allow; theme, language and goals sync via your own iCloud ◎ Free and Pro - Free: stress status, current-period trends, sleep analysis, mood, water, widgets and complications, relaxing breathing - Pro: live stress monitoring, month/year and past-period trends, all breathing rhythms, full workout records - New installs get 24 hours fully unlocked, no payment first ◎ Health disclaimer Stress gives no medical advice or diagnosis and is no substitute for professional care.

◎ New • Stress alerts are quieter: only meaningful changes notify you, dense samples are confirmed first, and both rising strain and easing off can trigger a notice. Choose Smart, Every update, Low disturbance or Rarely in Settings. • Smart water reminders follow when you actually log water, pause after you hit your goal or leave the window, and support amount tiles plus long-press logging of your usual cup — including on Apple Watch. • A one-line summary shows whether the past month’s recovery is improving, declining or steady, with clearer colors for each. • Eligible workouts can mark a recovery period; sleep stages compare with your personal baseline; App language syncs to Watch and widgets. ◎ Improved • Stress shows four clear states instead of a numeric score, with a clearer today summary and peak moments. • Detail transitions, Today loading and date switching feel steadier; Trends fits in one line and monthly summaries compare with last month; sleep tips better match your usual schedule. ◎ Fixed • Clearer empty activity rings; opening Stress from a watch face lines up with that sample; swipe-to-dismiss and HRV detail number flicker are fixed. ◎ Thanks • Thanks to community members who flagged frequent stress alerts, asked for water reminders, and preferred stress status without a numeric score.
