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.

Tonic

iPhone

A 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.

About

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.

Principles

Privacy first Native iOS No ads, ever Indie forever
