HOUSTON – McDonald’s is offering free fries through the end of the year on Fridays. 

There are a few things to remember to redeem the offer, though: The fries must be purchased via the burger giant's app with at least a $1 purchase. The offer also excludes tax and can only be used once every Friday. 

Users must also register with the app on their Apple or Android device.
