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 - Six rhythms: Relaxing 4-4, Balanced 5-5, Wave 4-4-6-2, Deep 4-7-8, Focus 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 - If your body worked harder overnight, a gentle morning note — a nudge to rest, never a diagnosis ◎ 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 - Fits iPhone Duo, iPad split view and wide windows; 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, balanced and wave breathing - Pro: live stress monitoring, month/year and past-period trends, deep, focus and snore-relief breathing, 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.

Walking, a vehicle, or a recent workout pauses it, and Today says why. Widgets and watch faces follow along, and rectangular Lock Screen and watch-face widgets add today’s chart. Trends includes sleep score. Sleeping heart rate and breathing are colored against your own usual level. ◎ Improved • Sleep tips follow what lowered the score. If you went to bed early but still slept too little, the shortfall is made up in the morning. Going to bed earlier than usual no longer costs points just because the time is late. Monthly dates appear about every five days. The stress trend separates the chart from the numbers. The tab bar shrinks as you scroll down. ◎ Fixed • Stress times match this measurement, and Realtime mode no longer switches back on its own. Closing a detail no longer jumps, and overlapping peak and latest points draw as one dot. ◎ Thanks • Thanks to community members who flagged crowded monthly dates and Realtime mode switching back on its own. ### 1.0.3 — 2026-09-25 ◎ 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. ### 1.0.2 — 2026-09-12 ◎ New • Sleep details can now be viewed by day, week or month, so one night is no longer mixed with the whole week. • Jump to any past day from the calendar beside the week strip on Today. • Settings has a new Apple Health page, so you can see which data is connected and whether it has recent readings. • Personal Baseline now includes your usual bedtime, alongside HRV and resting heart rate. ◎ Improved • Week / Month / Year on Trends stays at the top, so you can switch the period without scrolling back up. • The stress bar is now four clear segments, and your score appears next to the status. • Personal Baseline follows your recent weeks more closely. If HRV stays low or picks up, Today adds a gentle note, and your stress reading is not quietly treated as the new normal. • Daily Goals are easier to edit, with the same card style for sleep, water, steps and daylight. ◎ Fixed • Sleep trend hours no longer add overlapping sources together, so totals match what you actually slept. • Moods logged on a past day are saved to that day, not today. • Large numbers such as steps, calories and water now group digits, so they are easier to read. • Resting heart rate no longer appears on days that have not started yet. ◎ Thanks • Thanks to community members who asked for a calendar on Today, a clearer Health connection page, more accurate sleep totals, grouped digits on large numbers, a resting heart rate chart that stays on real days, day-by-day sleep details, and period controls that stay on screen in Trends. ## Apps similar to Stress HRV | App | Rating | Price | Category | | --- | --- | --- | --- | | [Welltide：HRV压力监测](https://appshunter.io/ios/app/welltidehrv/id6794986736) | — | Free | Health & Fitness | | [FeelWatch:HRVStress&WatchFaces](https://appshunter.io/ios/app/feelwatchhrvstress-and-watchfaces/id6775738159) | 5.0 (1) | Free | Health & Fitness | | [FloFlo: HRV & Habit Tracker](https://appshunter.io/ios/app/floflo-hrv-and-habit-tracker/id6742727455) | — | Free | Health & Fitness | | [Stress Check: HRV for Watch](https://appshunter.io/ios/app/stress-check-hrv-for-watch/id6780021792) | — | Free | Health & Fitness | | [Simple Stress Watch](https://appshunter.io/ios/app/simple-stress-watch/id6770392749) | 3.6 (8) | Free | Health & Fitness | | [StressMind: AI Health Monitor](https://appshunter.io/ios/app/stressmind-ai-health-monitor/id6752275943) | 5.0 (1) | Free | Health & Fitness | ## More apps by Sleep Pilot Technology Co., Ltd. - [Sleep Pilot: Sleep Tracker](https://appshunter.io/ios/app/sleep-pilot-sleep-tracker/id6447691672) - [Truth or Dare - Dirty Game?!](https://appshunter.io/ios/app/truth-or-dare-dirty-game/id6474557201) All apps by Sleep Pilot Technology Co., Ltd.: https://appshunter.io/developer/1682165802 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
