Mochi: AI Stress Monitor

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.
