Trello: Essentially Digital Sticky-Notes on Steroids
If you are anything like me, writing things down is essential for getting them done in a neat and organized manner. Most phones have nifty calendars and reminders built in, as do most computers, but their functionality leaves a lot to be desired.
Trello fixes this by providing an app that allows you to customize several checklists at once so you can keep track of your busy day. As you go along, Trello allows you to check things off, message other people, set reminders, anything you might need. Better yet, the service is free to sign up for!
