I have been using the BlackBerry 10 calendar app way more recently especially with its beautiful daily agenda and built in BlackBerry Hub access. I have learned of two useful gestures in the calendar app that I wanted to make sure everyone knew about. There are loads of useful features in the app including being able to see who you are meeting with on a day to day basis. My favorite is the pinch gesture in the Week view tab that lets you zoom in and out of the daily view.
The last gesture I wanted to share with you I learned from Ty at the BlackBerryHelp Blog. He pointed out that you can get easy access to a six month view if you simply touch and swipe down anywhere near the middle of the month view and you will get a six month calendar dropdown. I love finding little features like that.
