Mini Popup Calendar… A mini calendar with a simple reminder feature. The reminder feature will let you enter a message to be displayed on a certain date & time of your choosing.
The calendar can be used as is. Just launch and go, or add to your doc bar or login/start up items.
The reminder feature needs the app to be running in order to work. To make best use of the reminder feature, add it to your login/start up items. It can work without doing so, but you will need to launch the app yourself.
Clicking on the arrow buttons you can “flip” through the calendar. Mini Popup Calendar is free. If you use Mini Popup Calendar a $10 donation would be appreciated.
