Remind Me is, as its name implies, an application designed to help you keep track of the tasks you need to complete during the day. This program sits quietly on your Menu Bar, communicates well with Mac's Reminders app (a productivity tool developed by Apple), and comes with a straightforward interface.
You can work with this app whenever you wish to remember project due dates, shopping list items, scheduled meetings, and many other tasks and events. The program adds all entered memos to Mac's Reminders records and works in the background without using a large amount of CPU resources.
Another good thing about this tool is that it allows you to set a global hotkey to immediately launch a new reminder window.
The only aspect I don't like about this program is the fact that you can lose the reminder you're working on (entering the necessary details) if you click the "gear button" which gives you access to the program's Preferences menu. Hence, make sure you don't open the Preferences panel before saving the current reminder item.
To conclude, Remind Me is a simple yet efficient program that provides you with an easy and quick way to set reminders on your Mac. The app is very simple to handle, lets you use shortcut keys for quick entries, and comes without a price tag.
