Cosmo Calls Mobile

Cosmo Calls is an offline space companion for everyone who loves space, sound, and small games. It combines four lightweight modules in one place, and everything you do stays on your device.

Star Quiz offers a round of space questions with a bonus for a series of correct answers in a row. Call Sign Forge turns any entered word into a unique space call sign that you can copy and save. The Signals panel plays seven short space sound sketches synthesized inside the app, each with its own short description. Space Cards allow you to flip through a deck of cards with astronomical facts and build up a series of discoveries.

Your best score, number of rounds played, and series are saved locally, so you can continue where you left off. The interface is available in English and Ukrainian, and you can switch languages ​​at any time from the menu or settings screen.

Because the entire experience is self-contained, the app opens quickly and works anywhere, whether on a plane, on the subway, or just at home. For a full data processing policy, see the Privacy Policy link inside the app.
