Your habits, as a grid you can actually see. Grid turns your habits into a contribution grid, like the one developers get on their code profile. One tap fills a square. Green builds up. Streaks become obvious, and so do the gaps. HOW IT WORKS 1. Add a habit. Three are free, and you do not need an account. 2. Tap the square when you do it. 3. Watch the grid fill in. That's the whole app. WHY A GRID AND NOT ANOTHER CHECKLIST A grid shows a whole year at once. You do not need to open a chart to know how the last three months went: the colour tells you in half a second. Missing a day stays visible instead of disappearing, which is exactly why people keep going. FREE, WITHOUT LIMITS - One-tap tracking and the full colour grid - Home-screen widgets, with no upgrade prompt - Streaks, stats, Perfect Days - 3 habits, 30 days of history, forever - Nothing to sign up for, no ads, no data selling, no social feed GRID PREMIUM - Unlimited habits - Full grid history, not just the last 30 days - Streak rescue and deeper streak analytics - Habit autopsy and load coaching: see which days and habits actually hold - AI-written weekly reviews - Clean share cards without a watermark - Custom colours and icons, CSV export - 7-day free trial, then $1.99 per month or the annual plan. Cancel anytime, and your grid stays yours. BUILT FOR REAL LIFE Choose which weekdays count toward a streak, so a gym habit on Mondays, Wednesdays and Fridays still builds one. Turn on vacation mode and a planned break stops counting against you. Set a reminder for the time you actually do the thing. NEVER LOSE YOUR GRID Sign in once and your grid syncs. New phone, reinstall, lost device: your squares come back with you. Grid Premium is an auto-renewing subscription charged to your store account and can be cancelled any time in your store settings. Prices vary by region.
