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 from 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 gap between the sleep you got and what your body needs, over your last 14 nights. Tap and hold the card for a breakdown. Recovery isn't linear, but steady nights add up.

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

EDITABLE, CONTEXT-AWARE HISTORY Tap any night to tag what mattered: late workout, travel, illness, hot flash, night sweat, heartburn, kid woke me. Alcohol, cycle, hot flashes, night sweats, and heartburn 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, time in daylight, overnight blood oxygen, and sleeping wrist temperature. Press and hold any card or progress bar for the research behind them.

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

GENTLE NOTIFICATIONS, NEVER AT 3AM Mendtide pings you only when your 14-day sleep debt moves an hour or more vs last week. At most once a week. No daily recaps. No streak nags. Nothing between midnight and 5am. Toggle each in Settings.

A SAFE SPACE AT 3AM The Journal is open at any hour. No scores. No debt math. No graphs. 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. Tag a night as "kid woke me" and tomorrow's plan adapts. Log pregnancy or lactation in Apple Health and Mendtide matches your stage: six weeks postpartum is the statistical low point, and most people are back past their pregnancy baseline by six months.

PERIMENOPAUSAL WOMEN (40 to 55) Hot flashes, night sweats, and cycle disruption are first-class context, not edge cases. Log a hot flash and the night tags itself. Mendtide reads your cycle 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.

THE COACH Chat with an AI coach grounded in sleep science, your own data, and strict safety guardrails. It now shows the research behind a mechanism right under the answer. It sees your real numbers: last night's sleep, HRV, sleep debt, training load, caffeine, cycle phase, your schedule, and your context tags. It won't pretend to be your doctor.
