The studio

Private by default. Quiet by design.

Rockenberg apps work on your device first. Your data stays there unless you share it or switch on an optional online feature. One person, a handful of apps, no growth hacks.

Free at the coreEvery feature works for free. A subscription can make some of them better, never unlock them.
No adsNothing between you and the thing you came to do.
Private by defaultOn-device first. Anything online is opt-in and says so.
