About 0n1 Studios

Independent · mobile & desktop

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

The name

0n1 is written with a zero (zero, n, one) and pronounced "oh-nee". Said out loud, we're Oni Studios; either spelling will find us.

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 manipulative monetization. Many of our games are free to play; where a game charges, the price is plain: a one-time unlock for most, one clearly-priced optional subscription for Everywhen, never a manipulative hook. It works offline, and anything we sync (like your progress) stays in your own iCloud. That principle shapes the whole studio. Read why we work this way →

On the workbench

More 0n1 titles are in development: Hunt (a Victorian monster hunt: London, 1887, four facts to prove about something that isn't a man, then a real-time fight), Worldwright (a time-travel game on a simulated history: go back into the eras of one place and bend what happened), and Everywhen (an interactive audio tale, a new one every other day: press play, listen, choose your path; no story ever has to end).
