In celebration of National Ice Cream Day on July 16, 2017, McDonald’s is celebrating its iconic vanilla soft serve by treating fans at participating restaurants nationwide to free vanilla cones.

Guests wishing to enjoy a free Vanilla Cone need to download the McDonald’s mobile app and redeem the Free Vanilla Cone on July 16 between 2 p.m. and 5 p.m. in their local time.

Once you have downloaded the McDonald’s App, complete the registration process using a valid email address. You will need to enable “Location Services ” in your app settings in order to obtain available offers at the restaurant you are visiting.

One lucky person will also win McDonald’s soft cone ice cream for life by being randomly selected among those redeeming their free ice cream.

Participating restaurants do not include any McDonald’s in Walmart, gas stations, malls, amusement parks, hospitals, airports, schools, parks zoos or museums.

The full rules can be found here.
