About this app

StackDays turns habit-building into something you actually want to open every day.

TRACK WHAT MATTERS
Log daily habits with a clean, colorful dot-grid heatmap — see your consistency at a glance, just like a GitHub contribution graph for your life. Give each habit its own accent color and pick from flexible tracking types: simple check-offs or quantity goals.

STAY MOTIVATED
• Streaks that matter — miss a day and watch it reset, or use a Streak Freeze to protect your progress
• Streak Powers let you recover a missed day from the last 7 days
• Unlockable badges reward consistency and milestones
• Daily tips keep you focused on why habits stick

SEE YOUR PROGRESS
Dive into Day, Week, and Month stats views, a full consistency heatmap, and weekday breakdowns that show exactly when you're strongest — and where you slip.

BUILD WITH FRIENDS
Add friends, compare streaks, and join challenges together. Nothing keeps you consistent like a little friendly competition.

WIDGETS & SYNC
Check your streaks right from your home screen with the StackDays widget. Connect Health Connect to sync activity automatically into relevant habits.

MADE TO FIT YOUR LIFE
Edit past days if you forget to log, customize colors to match your style, and get smart reminders and streak-risk notifications before you break a streak.

Start stacking your days — small, consistent habits compound into real change.
Build streaks, stack habits, and grow with friends — one day at a time.
