iPhone
Hit your daily step goal and your fish thrive. Miss too many and the tank clouds over. A walking game where real steps keep a reef alive.
Your steps grow a living aquarium.
FinSteps turns the walking you already do into a reef full of fish. Hit your daily step goal and the tank thrives — you earn pearls, unlock new species, and keep the water clear. Let it slide and the water clouds over and your fish start to suffer. It's a virtual pet that lives on your real-world movement.
NO GPS. NO ACCOUNT. NO ADS.
FinSteps reads one thing from Apple Health — your step count — and it never leaves your iPhone. You don't have to walk anywhere in particular, change your pace, or look at your screen. Just walk like you already do.
WHAT YOU DO
• Set a daily step goal (default 8,000, adjustable 1,000–100,000)
• Walk. Your iPhone counts steps automatically through Apple Health
• Hit your goal and watch the celebration when you cross the line
• Earn pearls and spend them in the shop on fish and decorations
• Grow streaks. Unlock milestone badges and rare species
FISH TO COLLECT
Start with a hardy guppy that survives even the roughest week. Streak your way to a Betta, Seahorse, Pufferfish, Jellyfish, Octopus, Sea Turtle and more. Prestige streaks at 90, 180 and 365 days unlock exclusives you can't buy — the Koi, Manta Ray and Golden Arowana.
STREAKS THAT REWARD YOU EARLY
The first three streak days each unlock something. You'll see progress on day one, not day seven. Week Warrior, Fortnight Fin, Monthly Master and beyond wait for the long haul.
FORGIVING BY DESIGN
Miss a day and you still earn a few effort pearls for what you walked. Fish take a heart of damage, but the tank recovers fast when you come back. Even fish that pass on rest in a Memorial for three days — bring them back with pearls before they float away for good.
PRIVATE BY DEFAULT
FinSteps has no accounts, no servers, no analytics and no ads. Your aquarium, your streak and your history live locally on your device.
REQUIREMENTS
• iPhone with iOS 17 or later

Fixed a problem that kept the store from loading, which left some new players stranded outside their tank. Subscriptions open properly now — thanks for waiting.
