How long is your to-do list? Don't answer. We know: long. Trello can vastly improve both your personal and professional life by helping you to get organised. This popular project management tool allows you to easily switch between tasks and delegate to members of your team or family.

Create a board for each project (Santa's Christmas plans, for example) and within each board you can add lists (naughty, nice, getting coal). On each of those lists you add cards which you can organise, easily shuffle between lists, assign to certain people and fill with information, such as checklists or due dates. If you like, you can colour code everything and suddenly everything becomes surprisingly simple to track.

For example, if you're planning a trip you can make a vacation board with several lists that note what reservations you’d like to make, clothes you should pack, and sights you absolutely must visit.

Then you can populate each list with tasks (“book a table for 8 p.m.,” “pack a bikini,” “visit the farmers market”).

The latest update gives you a calendar Power-Up. Toggle this on and you'll get a quick view of all the cards that have upcoming due dates. Select a date on the calendar to see everything due that day and quickly mark items as complete.

There are some great little touches in the app. After you’ve copied a link, Trello automatically asks whether you want to add it to your card when you tap the attachments icon. And, there's a colourblind setting, so if you can't tell your reds from your greens, the app will show you patterns instead.
