tsyum, 
If you appreciate your calendar app, what is it?
Of course I’m happy to pay a bit, since great tools are a lot of work to build and maintain, so, no need to be “free”.
Features I’m wanting:
- recurring tasks
- ability to have multiple calendars that can be toggled on/off
- due dates that can be checked off
- notes would be great as a distinct feature, visually different
