A to-do list assumes you are the same person every day. You are not.

Chamba starts by asking how you actually are — energized, in flow, meh, drained, anxious — and matches three to five tasks to that answer across four fixed energy lanes. The same backlog produces genuinely different suggestions depending on how you check in. That is state-based matching, not filtering or sorting, and it is the thing a neighbouring to-do app cannot copy by adding a filter.
