EccoSphere

A calm aquarium from sound

Free · Designed for iPad. Not verified for macOS.

Turn a few seconds of everyday sound into an ecco, watch it in your aquarium, and enjoy outings, rock-paper-scissors, and EP (ecco points). Your sound does not stay. Only a small ecco remains. EccoSphere processes 5–10 seconds of everyday sound on your device and turns it into an ecco with its own colors and shape. The recording itself is not stored or sent. • Create an ecco from sound • Watch your own eccos in a private aquarium • Keep them in your Library • Send an ecco on an outing and see what happens when it returns • Enjoy automatic rock-paper-scissors matches • Check your history and rankings • Collect EP (ecco points) and exchange them for aquarium themes and decorations • Adjust your aquarium theme, decorations, BGM (background music), and SE (sound effects) You can grow an ecco on this device without signing in. Sign in to connect supported data to your account and expand what can be restored on another device. Recordings are never transferred. Sign-in and a network connection are required for some outing, match, ranking, and EP features. An opponent ecco is shown only where needed for game results, history, and rankings; it is not stored in your aquarium or Library. Core features are free. EP (ecco points) are non-monetary points used only in the App and cannot be purchased, redeemed for cash, or transferred.
