Prioritize, don't just track
Most to-do lists help you remember. Stack helps you decide what to do next. Drag to reorder. Top of the stack is what you work on next.
Not all tasks are equal
Some tasks are high leverage — the difference between good and great execution is 10x. Some are neutral. Some can be delegated entirely. Stack helps you see the difference before you dive in.
No due dates. Just priority.
Priority is your position in the stack, not a date on a calendar. If something keeps getting outranked by other work, that tells you more than a deadline ever could. Most apps organize around when. Stack organizes around what matters.
