Momenta B.V. has introduced Agenda, its debut application for macOS (10.12 and higher). Agenda is a date-focused note taking app for planning and documenting projects.
The app is made available under an interesting sales model: it’s free to use with no time restrictions, but an in-app purchase will permanently unlock all premium features released in the coming year. With Agenda, you group notes for each project into a timeline.
Notes can be manually ordered in the timeline, or given a date. They can also be coupled to events in the Calendar app.
