Other than the rather spartan layout which gets cluttered too quickly, I don’t have much to complain about with Calendar on the Mac. It’s free. It syncs well with iCloud to other devices. Adding events is simple enough. What’s missing in Calendar is what you’ll find in When.
When keeps a list of Calendar-like events and displays, in list form, when they’re due or if past already, when they occurred. The beauty of When is the simplicity of the display. It’s a simple list of events, each with a name, a date, a description, notes if you wish, but you can organize with categories.
When is smart enough to notify you with an alert prior to the event. Today, future, or past events can be displayed in a popup menu with a click.
How does When compare to events in Calendar?
In Calendar you’re forced to find the events, or hope they catch your eye as you scan through all the events you’ve entered in the calendar view. When requires only a click to open a new event. Then just add the date, description, notes and set the alert reminder. When simply displays all the upcoming events in a nice vertical list.
When is a bit like a mini-Calendar and works great for remembering holidays, birthdays, graduations, or anything else where you need to know a few days before the event occurs.
