Rendezvous is unique because it mimics how appointments are typically scheduled using a traditional week or day planner. There are many calendar apps for the iPad and all of them can be used as an appointment book, but because all of these apps include far more features that are just not needed to keep a simple appointment book, they can be overwhelming.
Rendezvous is ONLY an appointment book; nothing more. So, it’s easy to learn. But to further assist in making your transition to Rendezvous smooth, this site explains all the features and how to use them.
