Office 365 vs Calvetica

Office 365 is laid out the same way with a similar ribbon interface that will be instantly comfortable to long-time Microsoft Office users.

Linux never got it together

Multiple people can work on the same document at the same time.

Calvetica's month view offers continuous scrolling and shows how long events are, and whether or not they overlap.

For each event entry, a custom color can be assigned.

For some reason, many calendar apps don't include task lists. Calvetica offers tasks that sync between devices, and come with a snooze option.

To add an event, just tap and hold. Two fields will appear, event name, and time. When filling in the time field, a number pad will automatically be displayed for faster entry.

Alerts are automatically added and set to go off at a standard custom amount of time before the event.
