Mendtide: AI Sleep Coach

3am wake-ups, hot flashes, night feeds: the messy nights most sleep apps ignore. Today's plan in 30 seconds. No anxiety scores. No shame. Now with even more integrations.

The sleep coach for the people most sleep apps forget, powered by personalized intelligence.

If your nights look nothing like the textbook 8 hours, whether because of a newborn, perimenopause, shift work, jet lag, or just life, Mendtide is built for you. No scores. No red "bad night" warnings. No shame.

SLEEP DEBT, WITHOUT THE GUILT Sleep debt is the running gap between sleep you got and sleep your body needs, summed over your last 14 nights. Tap and hold the debt card for a plain breakdown. Recovery isn't linear, but steady nights add up.

DECISION-GRADE, NOT DATA-GRADE Every morning you get a 30-second briefing that tells you what to DO today, not just your score. Every recommendation cites the sleep research behind it.

EDITABLE, CONTEXT-AWARE HISTORY Tap any night to tag what mattered: late workout, travel, illness, hot flash, night sweat, kid woke me. Alcohol and your cycle phase are read from Apple Health and tagged automatically. Tomorrow's coaching adapts.

SEE WHERE TO FOCUS The Trends tab covers sleep, movement, exercise, stand, steps, consistency, hydration, mindful minutes, mood, overnight blood oxygen, and sleeping wrist temperature. Press and hold any card or progress bar for additional information and the research behind them.

ON YOUR HOME SCREEN Mendtide widgets give an at-a-glance read of your morning plan or sleep debt. Lock Screen widgets show last night's sleep and your longest unbroken stretch. Calm mauve, never red.

GENTLE NOTIFICATIONS, NEVER AT 3AM Mendtide pings you only when your 14-day sleep debt moves by an hour or more vs last week. At most once a week. No daily recaps. No streak nags. No pings between midnight and 5am. Toggle each type in Settings.

SLEEP GUIDES Plain-language sleep guides inside the app.

A SAFE SPACE AT 3AM The Journal is open at any hour. No scores. No debt math. No graphs. Just space to brain-dump what's keeping you up.

BUILT FOR YOUR LIFE

NEW PARENTS (0 to 3 years postpartum) Fragmented nights are the norm, not a bug. Tag a night as "kid woke me" and tomorrow's plan adapts.

PERIMENOPAUSAL WOMEN (40 to 55) Hot flashes, night sweats, and cycle disruption are first-class context, not edge cases. Mendtide reads your cycle from Apple Health and frames a rough luteal-phase night for what it is.

SHIFT WORKERS, TRAVELERS, AND ATHLETES Pick your context in onboarding. Mendtide reads your workouts and adapts to your schedule.

THE COACH Chat with an AI coach grounded in sleep science, your own data, and strict safety guardrails. It sees your real numbers: last night's sleep, HRV, sleep debt, training load, caffeine, cycle phase, hydration, mindful minutes, mood, overnight blood oxygen and wrist temperature, your typical schedule, and your context tags. It won't pretend to be your doctor.
