I love that it's not just about appointments, but also events! It lets you see your calendar in different ways as well so having to remember what day of week something falls on isn't always easy with other apps out there. Sometimes when adding an event from another app or website into my appointment book will cause conflicts where both show up at once which can be confusing if i'm trying to choose one over the others. Also sometimes they don't sync very easily depending upon how often we use them. If someone has trouble using their phone/tablet calendars through their computer then this would solve all problems by syncing between devices seamlessly (i have no issues). This solves any scheduling discrepancies because our staff are able to look back months ago without being dependent solely off memory anymore since everything gets recorded digitally now instead of relying only on human memories.
