Stack your habits, protect your streak, and challenge friends to real goals. Accountability that actually sticks. StackDays turns habit tracking into something you actually stick with — because you're not doing it alone. WHY IT WORKS People are far more likely to follow through on a goal when someone else is watching. StackDays makes that visible every single day: stack up your habits, watch your streak grow, and keep your friends honest right alongside you. TEAM UP WITH FRIENDS Add friends with a simple invite code, see their streaks, and start real challenges together — group goals with shared progress, a leaderboard, and team chat to keep everyone accountable. SEE YOUR PROGRESS Day, week, and month views turn your habit history into real insight, so you know exactly where you're consistent and where you're slipping. GO PRO Unlock unlimited habits, full stats history, streak powers, and the ability to create challenges with friends. Stack up your days, one habit at a time.
