FocusReef is a focus timer and study timer with a pixel aquarium. Set a time, put your phone down and study or work. Every completed session earns coral, which you spend on eggs to hatch fish.

FOCUS TIMER
• Sessions from 10 to 120 minutes, adjustable in one-minute steps
• For study blocks, Pomodoro sessions, deep work and focused reading
• Every focus minute earns 10 coral, and your first three sessions count double
• Every session ends with a shell, with a bigger one from 30 and from 60 minutes
• Most shells hold coral or fish food, fewer hold aquamarines or an egg

IF YOU QUIT
• If you quit or stay out of the app for more than 30 seconds, the session is lost
• A random fish then turns into a skeleton for 3 days and earns no coral
• 3 aquamarines heal it right away, and you get aquamarines for focusing or in the shop

AQUARIUM AND COLLECTION
• 36 real species from guppy to Greenland shark, each with its own pixel art and shiny variant
• Three worlds: freshwater, the ice cave and, with FocusReef Plus, the deep sea
• Four rarities: common, rare, epic and legendary
• Museum with every species
• Fishing mini-game for food, eggs and name tags

PASSIVE INCOME
• Fed fish keep earning coral with the app closed
• This lasts up to 3 days after your last completed session, then they sleep
• Fish food comes from the shop, shells and fishing
