It's called The Canary Project, and it is an effort to help prevent texting and driving.
Here's how it works-- anytime a person uses their smartphone to text, facebook, or even look up something on the web, while they are traveling at least 12 miles per hour-- the app sends an alert to an accountability partner.
That partner could be a parent, spouse, sibling, friend-- who ever you'd like, then it creates a report card of sorts that tracks your phone usage while you're behind the wheel.
You can't delete the app from your phone, because your accountability partner is the one who knows the password.
It's an especially great app for parents, so they can see every time their child is texting and driving.
You can try this app out for free for seven days. If you purchase the app within the seven days, it costs $9.99. But, if you decide you want the app after the seven days, it will be $14.99, and you can add up to 10 phones per app.
