The AppGap is a nifty little app that allows you to add invisible folders to your BlackBerry 10 device so you can further customize the look of your home screen, and you can download it for free this week with a special promo code.

All you have to do is type in “AppGap2015” into the Redeem section of BlackBerry World, and you’ll get this clever app for free.

The promotion runs from today, January 12, 2015 until Thursday, January 15, 2015. That means you better jump on it while you can!
