JotPlan Standalone

It is a standalone version of JotPlan, and is equivalent to JotPlan except it does not allow cloud integration between iPad and iPhone.
The most user-friendly scheduler might just be a printed Letter-size sheet with a month's worth of appointments. On paper, you're not confined to grids—you can write what's most important in a big way and fit plenty of smaller details. It provides an overview at a glance, and you can fold it up to take it with you. And if you flip it over, it doubles as a notepad.

If you have an iPad and an Apple Pencil, you can do the same with JotPlan:

Your standard calendar appointments are displayed on the schedule. (You can also edit and add new ones.)
It follows a one-day-per-line format, so you have plenty of horizontal space to jot down anything you need on a digital Letter-sized canvas. (And if you can't fit it all, there's a notepad on the back screen.)
You can view the entire schedule in portrait mode on the iPad and zoom in on landscape mode.
