Why Sosta exists

Every calendar treated us like robots.

None knew if we were tired. None adapted when we crashed. None cared that a Tuesday after four hours of sleep is a different Tuesday. So we built one that does.

Who built this

Sosta is built by a small indie team. It took about six months of work, mostly evenings and weekends, mostly in small rooms with too many open tabs.

We'd tried Motion, Reclaim, Rise, Sunsama, and a handful of others. They all assumed that the version of you planning the week was the same version that had to live it. That's wrong about half the time. It's most wrong on exactly the days the calendar needed to be smart.

So we started writing one. Then we rewrote it. Then we rewrote it again.

What it took

We learned StoreKit 2, JWS receipts, App Store Server Notifications, HealthKit, ICS parsing, and FastAPI from scratch as we built. Three App Store rejections taught us Apple's rules properly. A Railway outage right before launch prep taught us to keep options. None of that lives on the website. All of it lives in the app.

What Sosta does

Sosta plans your week around your energy, deadlines, and goals. Drag in your calendar, drop in a deadline, and the day rebuilds itself when life shifts. Free tier uses smart scheduling. Pro adds AI drafting, AI replan, and Pip's reasoning on every block.

Sosta will not nag. No streaks. No daily score. No guilt notifications.

Sosta will not share your data. Calendar data stays on your device. Health data is read on the fly, never stored, never shared.

Who it is for

Students. Working people. Anyone juggling both. Anyone whose week should bend when life pushes back.

iOS only, for now. The waitlist is open and the App Store launch is coming any day.
