A living desktop aquarium with layered artwork, gently moving animals, lighting and a clock. Your apps stay in front of the view.

Sixteen: eight grand aquariums and eight home or café tanks. The places and artwork are fictional, with no affiliation to real aquariums.

Mac App Store and Microsoft Store releases are coming soon. The badges on this website will link to each listing when available.

macOS 13 or later, on Apple silicon and Intel Macs. Choose your display and frame rate in Home’s Settings.

Yes, all 16 scenes. The free version shows a text watermark; after five minutes, animals and scenery become shadow silhouettes.

No. It is a US$1.99 one-time purchase. Your store shows the local price and taxes. Mac and Windows purchases are separate.

Each Apply to Desktop starts a fresh five minutes. Purchasing removes the timer and text watermark, and unlocks an optional Shadow Mode toggle.

The included scenes work offline. Radio, support messages, purchases and purchase restoration need an internet connection.

An optional streaming music player. Press the record to play or pause; aquarium sounds are not required, and music does not start automatically.

No Walltank account is needed. Cursor gestures are processed on your device. Feedback sends your message, optional email and limited diagnostics only when you send it.
