a video is quite useless, but i can try to explain what this app does:
if you ever tried to use the default calendar, or any todo application, you should have seen that it requires lot of time to set up an event. This app is designed for planning your day, inputting (so for example if you've dinners, meetings, and so on and so forth) and showing in a intuitive way. The key is to notice the clock in the center of the screen. just imagine that with this app you can extend the hours lines (or even create new ones) and then wrote in between intervals the things you have to do during the day. That's nice hun?
as an added bonus, this app exports a calendar file, that can be imported in other applications like the default calendar, or calendar desktop widget. Or you can see your today's todos via the enclosed desktop widget. That's it.
