Thanks to Starbucks, iPhone users can download the popular to-do app Clear for free today only.

The process to nab the normally $1.99 app for free is pretty simple. First, you must download the free Starbucks app from the App Store, if you haven’t already. Go to the Messages section in the Home portion of the app, and you’ll see a message for the Pick of the Week.

After that, hit the download button and enter your iTunes credentials. Clear is now yours.

Hitting the App Store a little more than year ago, Clear has made a big splash. Taking a very simplistic approach to managing a to-do list, the app leverages the iPhone’s natural multitouch gestures along with a scheme that prioritizes tasks by color.

In our original review, Christine Chan said Clear “is the perfect simple to-do app, since it’s so intuitive.”

It made the move to the Mac in November. Even though it has a higher $15 price tag, that version does have some fun and new additions.

Clear was also named as one of our Top 10 Best Paid iPhone Apps of 2012.
