Read stress against your own HRV and resting heart rate — not a generic range. Works on Apple Watch. New installs get 24 hours fully unlocked.
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

This app nails the basics. The HRV stress monitoring is surprisingly accurate and gives me a clear picture of my stress trends. It’s lightweight, downloads fast, and takes up almost no space. The design is beautiful and minimal, and every feature feels intentional. If you want a focused HRV app without the bloat, get this one.

Really enjoying this app so far

It’s simple, clean, and easy to use. I like being able to see my HRV, heart rate, and stress levels in one place. The real-time stress tracking is probably my favorite feature, and I find it useful for checking how my body is responding throughout the day.
Developer Response
Thanks for your review! We're glad you enjoy the simple design and having HRV, heart rate, and stress all in one place. Great to hear real-time stress tracking is helpful. Thanks for using Stress HRV
◎ New
• Realtime mode updates stress between HRV readings using your heart rate while you are still. 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.
