About 0n1 Studios

Independent · iOS & Apple Watch

0n1 Studios is an independent studio crafting immersive mobile games for iOS. We build games we want to play — carefully made, atmosphere-first, and respectful of the people who play them.

What we believe

Games should earn your attention, not harvest it. Every 0n1 title is built privacy-first: no ads, no sign-ups, no tracking, and no in-app nagging. You buy or download a game and it is yours — it works offline, and anything we sync (like your progress) stays in your own iCloud. That principle shapes the whole studio.

What we make

Letterbox

Tile-swap word puzzles built from 314 famous quotes across history, film & music.

More 0n1 titles are in development, including Realm (a location-based discovery app for the real world), Adventure (bimanual gesture combat meets a location-driven RPG), and further projects under the names Strategoi and Rockstar.
