12 hour dial instead of 24 hour dial. Would probably mean fewer calendars could be seen, however, and might only work on the single day view. See attached mockup. Image on the left is what it would look like before noon, image on the right after noon.
Could this idea be developed to customisable time periods.
1) Set periods as favourites (eg. for work day / leisure time);
2) Ad hoc periods selected by dragging on calendar
3) Zoom feature per calendar item for a countdown visualisation.
Do you mean one ring for customisable time periods and the other ring for your events? Or do you mean a separate ring view per event, like a circular countdown? It would help to hear more about the particular problem you are looking to solve. :)
Please keep the 24 hour clock as an option
Oh absolutely!! PiCal is primarily a 24h dial app, because that makes so many other functions possible. Some people have told us they just can’t get their heads around it though so we thought we might offer 12h as an OPTION :D
