"Things - it's a real standard for these types of programs because of the excellent feature set and interface that is suitable for almost any level of the organization of tasks - simple enough for doing the simplest daily tasks lists ... but sufficiently developed to accompany the tasks of any ... Things provides the user with a unique combination of ease of use, excellent interface and flexibility that allowed me to stop using other organizers that I have used. "- Dan Frakes, Macworld

Things Cloud
Things Cloud stores your to-dos and keeps them updated on your Mac, iPad, iPhone, and iPod touch. All you have to do is turn it on in Things’ Preferences.

Quick Entry
Life is busy. It’s easy to forget something when you don’t write it down immediately. Things lets you enter new to-dos the moment they hit you.No matter what application you’re in, simply press a system-wide keyboard shortcut, and the Quick Entry window appears. Enter your to-do, save it, and get back to work. The next time you open Things, the to-do waits for you in the Inbox - you’ll never forget anything important again.

Easy from the start
You shouldn’t have to read a manual to become more productive.* Or try to understand complex inspector windows. After all, isn’t the whole point of a task manager to make your life easier?
With Things, everything flows naturally. Out of the box, it comes with lists that are ready for your to-dos:

Even quicker with Autofill
You’re reading an email from a friend and she wants you to buy some things for the party. Or your boss wants you to prepare a presentation. Just select the relevant portion of the email, press the Autofill shortcut, and the Quick Entry window appears. But this time, it has the selected text already added to the notes, together with a link to the original email - it’s magical. This also works from many other applications like Safari, Messages, Pages, Finder, etc.

Requirement: OS X 10.9 or later
