The base version includes:
- Week numbers
- Finnish holidays
- Flag days
- Calendar filtering (choose which calendars are active)
- Searching for calendar events
- Adding and editing calendar events
- A separate week view when used in landscape orientation

All calendar features use the system calendar storage, so all events ands modifications are automatically usable in other devices and calendar software as well (including the default iOS calendar).

The app works well in both iPhone and iPad devices.

Also, Finnish name dates and moon phases are available as in-app purchases. Name dates are valid for every day at least until the end of 2019. Moon phases are calculated for every day until the end of 2020 and are viewable in a separate moon calendar.
