You're deeper than you think. Every missed hour of sleep pulls you further underwater. Resurface turns your sleep debt into a living ocean โ 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 โ 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) โ Fresh air. You made it. - Shallow Waters (1โ20m) โ Light filters from above. - Mid Depths (21โ60m) โ The surface seems far away. - Deep Waters (61โ100m) โ Darkness surrounds you. - The Abyss (101m+) โ The pressure is immense. Every zone has its own atmosphere, colors, and guidance. Your progress isn't a chart โ it's a world you live in. LOG MORE THAN JUST HOURS. Track 11 factors that shape your sleep โ 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.

SleepTracker records your sleep automatically with an Apple Watch โ or with just your iPhone on the mattress โ and turns the night into a clear picture of your stages, heart rate, and recovery. No setup, no account, nothing to configure. No account. No sign-up. No email. No ads. Open it, allow Apple Health, and go to bed. HOW IT WORKS โข Wear an Apple Watch to bed and open the app โ sleep stages, heart rate, HRV, and breathing sync straight from Apple Health โข No watch? Set your iPhone on the mattress and tap Track Sleep with iPhone โ it uses movement and sound to estimate your night โข Numbers match the Apple Health app exactly, down to the minute WHAT YOU GET โข Sleep rings that show Sleep, Quality, and Deep at a glance โข Full stage breakdown โ Deep, REM, Light, and Awake โข Bedtime, wake time, time to fall asleep, and sleep efficiency โข Readiness, Sleep Fuel, and Recovery scores built from your real HRV โข Heart rate, HRV, SpO2, and respiratory rate with Apple Watch โข A smart alarm that wakes you in a lighter stage near your target time โข Sleep consistency, trends, history, and a calendar of every night โข Tags for caffeine, late meals, workouts, and stress, so you can see what actually changes your sleep BUILT BY ONE PERSON I built SleepTracker for myself, in a year when AI finally made something like this achievable alone โ then kept building whatever people asked for. No team, no investors, and no roadmap written by anyone but the people using it. And no subscription: sleep data you already own shouldn't be rented back to you month after month. YOUR SLEEP DATA STAYS ON YOUR PHONE Sleep and health data is read from Apple Health only after you allow it. Microphone audio is analyzed on your device and is never recorded, stored, or uploaded. There is no account to create and no profile to sell. No tracking of you across other companies' apps or websites, and nothing shared with data brokers. TELL ME WHAT TO BUILD See something in another sleep app that you wish this one had? Email mark@vibecode.review. I read every message and I build what people actually ask for โ that is how most of this app got here. Sleep better by understanding your nights, automatically.
