Little Tank: Betta Aquarium
A calm betta in your pocket
Free · Designed for iPad. Not verified for macOS.
Feed your betta, change the water and watch it swim. Soft music and nature sounds keep you company.
A little betta lives in your phone now.
Feed it and it rises to the surface to eat. Tap the glass and it may flare its gills or come over to knock back. A shy one hides behind the plants, a bold one patrols the tank, and a calm one simply drifts.
Change the water about once a week. Feed too much and it clouds up sooner, just like a real tank. Move the plants and driftwood wherever you like, near the front or far in the back. Stick the thermometer anywhere on the glass.
When you want to sit with it for a while, turn on soft music, a quiet heartbeat rhythm, or rain, waves, forest and crickets.
