Snowball

A voice-first habit tracker and journal that lets habits build on themselves.

Apr 2026 – present

Snowball combines daily journaling with a progressive habit system designed for people who want meaningful reflection without gamification pressure. There are no streaks to lose: you start with a few habit slots and unlock more through consistency, so the app grows with you instead of guilting you.

Journaling is voice-first — talk through your day and Snowball transcribes it. At the end of each week and month, Claude synthesizes your habit data and reflections into a personalized recap letter written in the first person.
