Roost: Stress & Sleep

HRV, meditation & better sleep

Free · In-App Purchases · Designed for iPad. Not verified for macOS.

Close your eyes and let a gentle voice unwind you. Reminders never repeat, stress and sleep come from your own data, and everything stays on your device. 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. EIGHT VOICE-GUIDED MEDITATIONS Deep Sleep, Grounding, Focus, Morning Wake-Up, Body Scan, Midday Recharge, Evening Unwind and Pre-Meeting Calm — every session carries gentle voice narration, so you can follow along with your eyes closed. While you meditate, the Lock Screen shows the current cue and time left. SMARTER REMINDERS Sedentary, hydration, and eye-rest nudges carry 22 messages each in a no-repeat rotation, and the ones you keep dismissing fade out. Pick a tone to match your mood: Gentle, Sassy or Minimal. Auto-silenced during meetings, focus, and workouts; skipped while you're already moving. Strong Apple Watch alerts reach you when it matters. MY TIMETABLE Lay out wake, lunch, reading and bed across your day and get pinged right on time, unaffected by quiet hours. One-tap templates for a workday rhythm or a self-care routine. 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, and Roost is offline by default with no account. The one networked feature is the optional step leaderboard (via Apple Game Center), and it stays off until you switch it on yourself. Available in English, Japanese, Simplified and Traditional Chinese, French, German and Arabic, following your system language. Upgrade to Pro with a single one-time purchase to unlock everything — no subscription, no ads. ——— Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
