Habits, seven-day trails & focus timer
Stonestack
Every check-in adds a stone.
Stonestack makes progress visible. Each habit you keep adds a stone to this week’s stack, each focus session adds another, and a seven-day trail builds a stack of its own. Miss a day and the stack simply waits for the next stone.
In development · coming to iPhone and Android in the United States
How it works
Choose a few small habits
Or pick a seven-day trail: sleep earlier, walk after lunch, read ten pages.
Check in or focus
Tap a habit when it’s done, or start a quiet focus session.
Watch the week grow
Every check-in and finished session places a stone; past weeks line up on your shelf.
