Not only is Agenda beautiful, It's fast and reliable. It makes me write down things that I would never write otherwise, even a small journal.
I track most things now in Agenda, vet appointments, chores, work projects... I feel I'm more productive than ever and I don't miss a thing.
The integration with calendar and reminders is perfection.
The only thing Agenda is not good for is writing big documents on it, but it's ok, I think is not in the scope for Agenda.
Congratulations to the developers, I love using Agenda. I hope you the best, can't wait for the upcoming updates.
