NBC - The fast food bacon battle is sizzling!

Wendy's offering a free treat all week.

Freebie alert!

Wendy's is giving away free Baconator Fries through Sunday with the Wendy's app.

Customers can get a free order of Baconator Fries at participating US locations with any Wendy's purchase and the fast-food chain's app, through February 17th.

The app is available for Apple and Android devices.

The in-restaurant offer will reset daily, but can only be redeemed one per day, per mobile app account.

Registration in the app also is required.

Wendy's is hoping it's bacon offerings will rise above the rest as restaurant chains have been dishing up a bounty of bacon specials and adding new menu items in recent weeks.
