Better defaults,
not more settings.
Sets Studio is an independent iOS studio built around roaming curiosity. We make small, focused tools, one at a time, finished properly.
Apps
Tonic
iPhoneA tonic for your habits. Good habits unlock your apps: reading, workouts, meditation, sunlight, tracked automatically. The apps that only need boundaries get limits that fit.

What we do
We follow curiosity to real problems and build the small tool that solves one of them well. Right now that’s how people use their phones. We go where the next problem leads.
How we build
Native Swift on Apple’s own frameworks: Screen Time, HealthKit, WidgetKit. No ad SDKs, no cross-app tracking. We use everything we ship, every day.
What we believe
Intellectual honesty. Plain claims, no dark patterns, no engagement tricks. The measure of our work is what changes in your life, not how long you spend in our apps.
