Make yourself at home
How do I change the lighting?
In Habitat, choose Daylight, Warm sunset, Cool lagoon, or Moonlit night. Adjust Brightness and Color temperature independently. Use Movement for a slower pace and turn bubbles and particles off for a quieter view.
How do feeding and glass cleaning work?
Choose flakes, pellets, or brine shrimp, then tap Feed fish. Fish swim toward individual pieces and take bites. Wait for the meal to finish before serving more. For cleaning, tap Clean glass and rub your finger across the aquarium. Quick clean is available as a touch and accessibility alternative.
Can I save more than one tank?
Yes. Choose one of the three Saved aquariums slots and tap Save. To return to an arrangement, select its slot and tap Load. Saving replaces the arrangement in the selected slot. All slots stay on this device.
Does the app work offline?
Yes. The iOS aquarium, artwork, generated sound, help, privacy policy, and terms are bundled. Optional email and external links need a connection. There is no login or cloud synchronization.
How do the timer and sharing work?
Use the timer icon in the iOS app to start a 2, 5, 10, 15, or 30-minute relaxation session. It fills the aquarium view while you unwind. The sharing icon captures the visible aquarium and opens the system share sheet. No photo-library access is needed.
Is this a subscription?
No. The planned App Store release uses one upfront purchase with all included fish, food, and lighting. The final price appears in the App Store. There are no subscriptions or in-app purchases.
How do I reset or delete my aquarium?
Open the iOS Settings sheet and choose Reset aquarium and saved tanks. This removes saved arrangements and restores the default aquarium. Native motion and haptic preferences can be changed separately. Deleting the app removes local app data, subject to Apple backup settings.
What about iPhone Duo and iPad?
The app resizes its aquarium and rearranges controls as display space changes. It supports portrait and landscape on iPhone and iPad. Simulator screenshots show the current build; physical-device folding, performance, and battery testing remain part of release validation.
