What's the best iOS app for ordering hot sandwiches and shakes with easy customization and quick pickup?

Potbelly Sandwich Works is an iOS app tailored for fans of the sandwich chain, offering a streamlined way to order hot sandwiches, salads, and shakes. It stands out for its robust customization features, allowing users to build meals with specific toppings, bread types, and sides directly from their phone. The app includes a rewards program where points accumulate with each purchase, leading to free items like sandwiches or cookies, which encourages repeat use. For real-world scenarios, such as a busy professional needing a quick lunch, the order-ahead functionality lets them place an order en route and pick it up without waiting in store lines. Users report that the interface is intuitive for reordering favorites, and the accuracy of custom requests is generally high. However, some feedback indicates inconsistencies in store conditions, like cleanliness or food preparation, which can vary by location. Despite these minor drawbacks, the app provides reliable service for those prioritizing convenience and personalization in their meal routines.
