The first hundred days are where everything decides itself. Stop trying and start showing up.
Most habit apps assume you already know what to do. First Hundred is different. We built complete 100-day journeys for the things people actually struggle with — the patterns that keep you stuck despite trying to break them. Pick the one that's been on your mind. We give you exactly what to do each day. You just show up.
A new you, 100 days from now
Real change doesn't come from streaks or willpower. It comes from showing up every day for long enough that the new behavior becomes who you are. First Hundred gives you a 10x10 grid — 100 squares representing 100 days. Each square is one day you did the work. Watch the grid fill, watch yourself change.
Hundreds built around real patterns
Each hundred is a complete 100-day plan built around the patterns that keep people stuck. Every day is one short instruction designed to break the cycle, one square at a time. Or build your own hundred if you have something specific in mind.
Document the change
Log each day with a photo or a color, a rating, and a note if you want one. Each square becomes a record of that day — the easy ones, the hard ones, the breakthroughs. Tap any completed square to revisit what you did and how it felt. Your hundred becomes a living document of who you're becoming.

Built for the version of you that's tired of trying
