Your daily steps, a world of underwater discoveries. Step Fish brings everyday movement together with a lively pixel aquarium. Whether you're taking a stroll, walking to work or going the long way home, collect steps, earn Fish Food and discover new creatures. Connect Step Fish to Apple Health and choose your daily step goal. Follow your progress, view the past seven days and keep your streak going. Spend your earned Fish Food on creature packs to discover random inhabitants across different rarity levels. From tropical fish and turtles to pufferfish, rays and Arctic animals, build your collection and choose who lives in your aquarium. Make their home your own with four backgrounds, corals, rocks, sunken columns, treasure chests and floating ice floes. Place decorations where you like, adjust their size and flip them to suit your design. Your layout is saved to your account. Watch fish explore caves and swim through arches while penguins rest on ice floes. Tap the water to attract nearby fish. Tilt your iPhone and watch the waves, plants and creatures respond. Trade fish with friends: connect using a code, choose your creatures and confirm the exchange to welcome a new resident. Keep your latest synced step count and daily goal in view with a mini aquarium widget on your Home Screen.
