Phone calendar apps are great, but they lack some of the functionality of desktop apps. If you are an Outlook/Office 365 user, then Calendar assistant will seek to fill in those gaps, so you'll have all the functionality - on your phone - that you enjoy on your desktop.
Do you want to see attendee's free/busy from your phone before you schedule a meeting? Calendar Assistant is the only app that can do it for you.
Do you want to be able to quickly see a list of times that are open for all your attendees so you can easily pick a time that works for everyone? Calendar Assistant is the only app that can do that for you, too.
