The Pocket Event allows you to store random undecided activities that you can subsequently schedule to your calendar turning them into more potentially firm events as opposed to cluttering calendar with too many activities you will never bring to fruition.
Tap the envelope icon on the top of the Calendar screen to open the Event pocket.
Drag content saved in the Event pocket to the Calendar to save as an event.
You can create Events from items stored in the Event Pocket. Unfortunately, not the other way around.
Images, text, memos and temporarily saved events can be managed. If images, text and memos are shared from different apps to the Event pocket, they are saved in there. Alternatively, events can be saved temporarily in the Event Pocket by pressing 'Pocket.'
Add a Facebook account to view Facebook event info.
Turn location info on to view information on the vicinity of the current area, such as famous restaurants and convenience facilities.
To-dos with no completion date can be added as events.
