Resurface - Sleep Tracker

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.
