Most notes apps lose track of time. You write something, it disappears into a folder, and a week later you can't remember why you made that decision or what you prepared for that meeting. Agenda fixes this. Every note lives on a timeline alongside your calendar. Prepare for next week's client meeting, capture decisions as they happen, and look back at exactly what led you here — all in one view.
