Stack - Daily Intentions

Stack is a habit tracker with a finish line.

Three habits. Ninety days. Then it is done. The stack ships, archives, and you start fresh. The cap of three and the ninety days are not limits to pay past. They are the point.

Most habit apps are built to keep you forever. Stack is built to end.

• Three habits. No more. The limit is the feature.
• Ninety days. A clean quarter, then a finish line.
• One honest skip a week. It holds your streak but shows as a skip, never a fake fill.
• The grid is the app. Ninety days of dots, filled in by hand.
• A home-screen widget with today's three. Tap to mark.
• Built in Liquid Glass for iOS 26.

No accounts. No subscription. No analytics. Zero data collected. Pay once. It is yours.
