Mochi: AI Stress Monitor
Stress & HRV Tracker for Watch
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
Meet Mochi - your stress, with a face.
Mochi is a stress companion for iPhone and Apple Watch. Instead of showing you a number and leaving you to interpret it, Mochi shows you himself: a small character whose color, mood, and surroundings reflect what your body is actually doing right now.
Powered by HRV (heart rate variability) and resting heart rate from Apple Health, Mochi turns physiological data into something you can feel at a glance — and gently nudges you toward the small daily habits that actually lower stress over time.
How Mochi reflects your day
- Calm — matcha green, sipping tea in morning light
- Balanced — sakura pink, holding a cherry blossom under a bright sky
- Tense — warm amber at golden hour, holding a mandarin
- Strained — lavender at twilight, wrapped in a small bundle
- Overload — deep blue at night, lit by a small warm lamp
Same Mochi, same scene — five emotional states, five times of day. A full arc from morning calm to evening exhaustion, lived through one character.
What's inside
- Today — Mochi's current state, your HRV and RHR, a short breath ritual
- Habits — sleep regularity, movement, mindfulness, daylight
- History — your stress timeline by hour, day, and week
- Body — HRV baseline, resting heart rate, VO2, biological age
- Settings — watch widgets, subscription, profile
Built on your own baseline
Mochi compares your HRV to your own 7-day baseline, not to population averages. "Above your usual" means more than a generic "good." Your body, your numbers.
Privacy first
No account. No cloud. No tracking. Everything stays on your iPhone.
Requirements
iPhone running iOS 17.6 or later. Apple Watch recommended for live HRV data.

Six new characters join Mochi on your wrist.
- Meet Macaron, Puffy, Croissy, Tirammy, Donny and Nattie. Mochi is no longer alone on your Apple Watch. Pick the character you like best and he'll show your stress in his own way, both in the watch app and in the watch face widget. You can preview each one before you decide.
- Your state right on the watch face. Add the Mochi widget and check in without opening anything. We've included a step-by-step guide, illustrated with real screenshots.
- Mochi now tells you what drives your stress. He reads through your data and names the likely causes instead of leaving you to guess.
- A full week of history, on any day. History now shows your last 7 days instead of the current calendar week, so you get the whole picture on a Monday rather than a single bar. Every day is coloured by its stress level, so a hard stretch stands out at a glance.
- Your history survives a reinstall. New phone, or reinstalled the app? Mochi rebuilds the past 30 days from Apple Health instead of starting from scratch.
- Rate Mochi and reach support straight from Settings.
- Fixes and polish. A completed purchase now unlocks everything right away, Mochi no longer interrupts your music or podcasts, HRV and resting heart rate load correctly when you scroll further back, and buttons are easier to tap across the app.
We're continuing to refine Mochi to deliver a more consistent and reliable experience across iPhone and Apple Watch.
