Studio Product

Kyzin is the studio’s own product. It keeps habits, tasks and personal metrics in one place — quick to update during the day, clear to review at the end of the week — so you change course from what actually happened, not from how the week felt.

What we built

01

Data model

One typed schema for habits, tasks and daily entries, so every screen reads the same data the same way.

DRIZZLE / TYPESCRIPTTYPED SCHEMA
02

Web & Mobile

The phone app and the web dashboard share one typed API, so a change on one side can’t quietly break the other.

03

Weekly Review

Queries shaped around the week, so the review is quick enough to become a habit itself.

POSTGRESQLWEEKLY

See the week. Change the next one.

“A habit is easier to change once you can see it.”
