Hi, I'm Ibuki 👋

I built Grain because I wanted the simplest possible habit tracker.

To me, building a habit comes down to two things:
lowering the barrier to start, and earning your own confidence through daily action.
I wanted an app where each tap quietly grows into self-trust — designed to reduce cognitive load, so you can focus on simply showing up.

If you miss a day, that's okay. Chasing perfection can quietly break the whole thing.
Just pick it up tomorrow. Your grains are still there.
