Residents
Mika, Puff and Lumi to start. Ember, Nori and Kelpie are earned. Marlo, a friendly reef shark, swims with Plus.
A focus timer that grows your reef.
Choose a task, focus for 10 to 50 minutes, and watch a calm 2D reef grow. No pets to keep alive, no streak threats, no Shells for sale.
Free core timer · Optional Reef Ritual Plus · iPhone & iPad
How it works
Focus. Grow your reef.
Choose an intention
Pick a duration — 10, 25 or 50 minutes, or anything from 10 to 180 — and an optional private task.
Focus without noise
Gentle Focus keeps you in charge. Deep Focus can shield the apps you choose with Apple's Screen Time controls.
See real progress
Every completed session earns Shells and grows your reef. Every 65, 120, 200 focused minutes and beyond, a new coral bloom appears.
Discover something new
New residents and decorations arrive at meaningful milestones — Nori after 300 focused minutes, Kelpie after 1,500.
Your reef
A collectible 2D aquarium you shape yourself
Choose a companion resident, place decorations on sixteen curated spots, switch habitats and keep every layout. Three residents swim in your scene at a time.
Decorations
Permanent unlocks for Shells — coral, kelp, rocks and special pieces. Never consumable, never lost.
Habitats
The Sunlit Starter Reef is always free. Moonlit Lagoon and Sunken Garden come with Plus, layouts kept even when Plus ends.
Calm, fair rewards
Nothing to keep alive. Nothing to lose.
Shells are earned by focusing and by the first reef feeding of the day. They are never sold.
Ending a session early keeps your focused minutes in your log. No reward, no penalty, no sad fish.
Missing a day resets only your streak counter — never your reef, residents or unlocks.
Plus never speeds up progress. Everyone earns at the same pace.
Interactive Reef
Feed your reef with a gesture — or a tap
Pinch to pick up food, drag, release. Draw a circle and your residents follow. Camera processing stays on your device; video is never saved or uploaded. Touch works just as well.
On-device only. Nothing is recorded.
Reef Circles
Focus alongside up to four trusted people
A private circle shows who is focusing right now, sends their companion resident to visit your reef, and grows a shared bloom at 500 verified focused minutes a week.
Members see only your chosen name, your companion and whether you're focusing, resting or offline.
Never your tasks, tags, durations or session times. No chat, no feed, no leaderboard.
Invites are private links. Opening one never joins — you confirm explicitly.
