— Proof, not promises

Apps that survive the 90-day test

Every project here is measured by one criterion: daily opens, long after launch day fades. No awards. No feature counts. Just retention curves that hold.

Daily habit tracker

Routr — 74% day-90 retention

Stripped to a single daily flow with no onboarding friction. The result: users who opened it on day one still open it on day ninety at three times the category average.

Personal finance tool

Ledger Light — 61% weekly active rate

Every screen decision was weighed against one question: does this interrupt the user or get out of their way? Fourteen features were cut before launch. Three remain.
