Subtrack doesn't tell you how to spend. It puts every commitment in one list and lets you decide — three states, no lectures.
Size is what it costs a year. Distance is how soon it renews. Brightness is how much you actually use it. Move your pointer through it — then put it in order.
Invite the people you already split things with. They see the list and the totals, and nothing else — no edits, no deletions. Set what each of them is on, and the number you actually carry comes down.
Subtrack is designed to give you visibility without turning your financial life into somebody else's dataset.
