Tidepool Tycoon
Grow a cozy seaside empire
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Build a tidal cove into a bustling harbor, watch it earn Shells while you're away, and set sail to come back stronger. A cozy idle tycoon with a living, glowing world.
Tap a tidepool, build a harbor, watch it come alive.
Tidepool Tycoon is a cozy idle tycoon where you grow a tiny tidal cove into a bustling seaside harbor — fishing huts, kelp farms, a glowing tidepool aquarium, a lighthouse, and more, each earning Shells on their own, even while you're away.
HOW IT WORKS
• Place and upgrade buildings along the shore — each earns Shells every second
• Tap buildings for bonus collections on top of your passive income
• Come back later to a "Welcome Back" haul of everything you earned while gone
• "Set Sail" to reset your cove for a permanent production boost — and unlock a brand new look for the whole harbor
A LIVING WORLD, NOT JUST A SPREADSHEET
• Shimmering, animated water and a slow day-to-night lighting cycle
• Gulls wheel overhead, crabs scuttle the shoreline, dolphins leap offshore
• Drag every building — and every decoration — anywhere you like. It's your cove, arranged your way
• Set Sail through four hand-illustrated biomes: Dawn Cove, Sunset Harbor, Moonlit Bay, and Aurora Tide
BUILT TO RESPECT YOUR TIME
• Full offline progress — your harbor never stops earning
• Daily streaks reward you for just checking in
• Free to play, with fair optional extras: remove ads, boost your offline earnings, or join the Tidepool Club for an ongoing production boost — never required to enjoy the game
Plant your first fishing hut and see what your cove becomes.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
New content update!
- Achievements: 22 milestones to unlock, each with a small permanent production bonus that Set Sail never resets
- Daily Quests: three fresh tasks each day for bonus Pearls
- Squalls: occasional storms roll into the cove -- tap through them to clear early for a bonus
- Two new buildings: Regatta Marina and the Bioluminescent Grotto extend your harbor further
- Rebalanced Set Sail: each voyage now feels like real progress, not a quick reset
Also fixes an issue where a cove could occasionally earn more than intended after a long time away, plus building-tap responsiveness improvements.
Fair winds, Captain!
