A Wonderful Time Management App: Trello
Using a time management app is one of the easiest ways to get more of something we wish we all had: Productivity. Here is a time management app continually rated among the top time management apps on the market, all with the goal of making you spend less time planning and more time doing.
WHY WE CHOOSE
Developed over ten years ago, Trello is used by more than 25 million people. No matter how you prefer to track projects and time, Trello always allows you to easily see who is doing what at a quick look, so you'll never drop the ball on an important project.
WHAT WE LIKE
•Videos to instruct you to use the app.
•Easy to connect with other tools you already use.
WHAT WE DO NOT LIKE
•It's for general project management only and big projects are difficult to deal withon it.
•Limited free offerings.
Every group member is on the same page, so it's easy for you to keep track of the process of the project you are working on. Trello has a lot to offer, including unlimited storage. Users can choose to pay $ 13 a month（you can get a 15% discount if you buy the yearly plan）to fully take advantage of the app.
With companies such as eBay and Fender on its user list, Trello is able to work for a wide variety of teams and projects syncing（同步）between different web servers, mobiles（iOS and Android）, and desktop apps（macOS and Windows）.
