Grain is the simplest habit tracker you'll ever use. No forms. No timers. No streaks to obsess over. Just tap and focus weekly progress. Tap once to record a small win. Tap twice to say you pushed further. Tap three times to mark a perfect day. Each tap is a grain — and over time, grains stack into something real. No account required. Everything stays on your device.
