Resurface

You're deeper than you think. Every missed hour of sleep pulls you further underwater. Resurface turns your sleep debt into a living ocean — and your goal is simple: rise to the surface. Your sleep debt becomes meters of depth. Skip a night? You sink. Sleep well? You rise. The entire app transforms around you — backgrounds darken as you descend and brighten as you climb toward sunlight. It's not just a tracker. It's an experience. FIVE OCEAN ZONES. ONE GOAL. - Surface (0m) — Fresh air. You made it. - Shallow Waters (1–20m) — Light filters from above. - Mid Depths (21–60m) — The surface seems far away. - Deep Waters (61–100m) — Darkness surrounds you. - The Abyss (101m+) — The pressure is immense. Every zone has its own atmosphere, colors, and guidance. Your progress isn't a chart — it's a world you live in. LOG MORE THAN JUST HOURS. Track 11 factors that shape your sleep — room temperature, noise, screen time, caffeine, stress, exercise, and more. Resurface calculates how your habits help or hurt recovery with an environment score that directly impacts your depth. CELEBRATE EVERY BREAKTHROUGH. Cross into a new zone? Full-screen celebration with particles, haptics, and a moment that makes progress feel real. Reach the surface? An epic event with sunlight, confetti, and your swimmer breaking through the waves. 20 ACHIEVEMENTS TO UNLOCK. From First Breath (first sleep log) to Diamond Sleeper (100-day streak), earn badges across five categories: Depth, Streak, Consistency, Recovery, and Special. WEEKLY INSIGHTS & SHARING. Weekly averages, depth changes, streaks, and consistency scores. Zone-specific sleep tips. Five beautifully designed share cards for social media — show your depth, celebrate milestones, or announce you've surfaced. SMART NOTIFICATIONS. Bedtime reminders, morning log prompts, streak protection alerts, and weekly reports — all customizable. HOME SCREEN WIDGETS. See your depth, zone, streak, and last night's sleep at a glance. Widget backgrounds match your current zone. PREMIUM. - Sleep Consistency Score (0–100 gauge) - Recovery Projections (days to surface at different sleep targets) - Apple Health sync with sleep stage analysis - Full sleep history - Data export - Priority support No ads. No social feeds. No gimmicks. Just a beautiful, focused tool to help you pay off your sleep debt — one good night at a time. See how deep you are. Start rising.

Most sleep apps show you a graph and leave you to figure out the rest. Sleepsyn is different. It tracks your sleep, explains what is happening, and guides you toward better nights without pressure, without guilt, and without making it feel like a chore. TRACK YOUR SLEEP Wear your Apple Watch to bed, and Sleepsyn syncs your sleep automatically. Don't have a Watch? Just log last night's sleep yourself in seconds. Tell Sleepsyn when you went to sleep, when you woke up, and rate your sleep. No complicated setup either way. The app does the rest. UNDERSTAND WHAT AFFECTS YOU Log your habits with the sleep log. Caffeine, alcohol, exercise, screen time, and stress. Over time, Sleepsyn connects the dots and lets you know how they are affecting your sleep. These are not guesses. They are your patterns, surfaced from your own data. KNOW YOUR CHRONOTYPE Take our quick 5-question quiz and discover whether you are an Early Bird, a Flexible Sleeper, or a Night Owl. Your chronotype shapes everything. Your ideal bedtime, your peak energy hours, and why fighting your natural rhythm always backfires. WIND DOWN BEFORE BED Fall asleep faster with tools designed around how your nervous system actually works. • 4-7-8 breathing — a science-backed technique that calms your nervous system in 76 seconds • Sleep sounds — rain, white noise, brown noise, ocean waves, fan, and more SEE YOUR PROGRESS Every Monday, get a beautifully designed weekly sleep card showing your average sleep, your best night, and how many times you hit your goal.
