Mr. Sub is a free mobile application developed by UEAT Technologies for Android devices. It falls under the category of lifestyle and subcategory of food & drink. This app comes with two main features: loyalty rewards and mobile ordering.

The loyalty rewards feature offers a buy-9-get-1-free deal on small and large subs. Additionally, users can get a free canned pop and free chips by signing up and a free small sub on their birthday. However, this offer is not valid for Super Size subs and Double Stacked Smoked Meat subs, and cannot be combined with any other offer.

The mobile ordering feature allows users to choose their preferred MR.SUB location, place their order in advance, and pay online. This way, they can avoid waiting in line and pick up their order at the store. Overall, Mr. Sub is a convenient app for loyal customers who are looking to save money and time on their favorite subs.
