About
Reef is a cozy focus timer with an aquarium that grows as you work.
Place an egg in the nursery and start a session. Your focus time is split into
sections with short breaks between. The egg hatches when your first section ends
and grows a little more with each one, until a new fish swims out into your reef.
Stay focused and your fish thrives. Leave the app mid-focus and it gets sick, but
come back soon and it'll recover.
• Hand-drawn reef with real 3D fish that swim, startle and school
• Goldfish, betta, pufferfish, angelfish and eel to raise
• Earn pearls for every focused minute and spend them on new species and decor
• Sunken ships, sea fans, sand dollars, bubble streams and more
• Name your fish and look back at everyone you've raised
• Set your own session, section and break lengths
• Gentle reminders when a section or break ends
No accounts, no ads, no tracking. Everything stays on your phone.
