This is a calendar, to-do list and project manager all in one. Superb. Beautiful UI, simple and intuitive, works like a charm. One two cons is that it only accepts google calendars, and that there's no native app for MacOS/Windows. I cannot convert to Edo Agenda unless I can use it with my work Office 365 calendar.
I use Edo Agenda for work and private live, mostly the tasks and events. It helps me to get an overview of my everyday tasks and events!
