Roost: Stress & Sleep

Roost is a stress, sleep, and habit companion for iPhone and Apple Watch. It reads your Apple Health data on-device to help you understand your body and steady your routine — fully private, no account, no servers. LIVE STRESS, AT A GLANCE Roost fuses HRV, heart rate, and sleep debt into a continuous stress score, drawn as a tiny mascot's face: relaxed, balanced, or overloaded. A watch-face complication keeps it on your wrist. OVERNIGHT RECOVERY HRV rebound, lowest heart rate, volatility windows — Roost tells you whether your body truly rested, not just how many hours you slept. BREATHE & UNWIND Several breathing patterns (4-7-8, Box, 5.5 resonant) with an animated orb, a per-second countdown, and haptic guidance on Apple Watch. Guided meditations — Deep Sleep, Grounding, Focus, Body Scan — help you downshift in minutes. SMARTER REMINDERS Sedentary, hydration, and eye-rest nudges with rotating copy; auto-silenced during meetings, focus, and workouts; skipped while you're already moving. Strong Apple Watch alerts reach you when it matters. A GENTLER WAKE-UP Gradual wake nudges you during light sleep; on iPhone a system alarm rings until you tap "I'm up"; your watch buzzes too, even when your phone isn't nearby. SEE YOUR PROGRESS Mood check-ins, weekly reports, a 30-day overview, achievements and streaks, morning and evening rituals — turn each day into a rhythm you can see. PRIVACY FIRST All analysis happens on your device; health data is never uploaded. Available in English, Japanese, Simplified and Traditional Chinese, following your system language.
