What's a good Android app for ordering fast food with rewards when traveling in the US?

Wendy’s is a practical choice for travelers seeking a reliable fast-food ordering and rewards app while in the United States. Its core functionality centers on streamlined mobile ordering for pickup or delivery, allowing users to customize meals and skip the line—a significant advantage when on a tight schedule. The integrated Frosty Key Tag rewards program, highlighted in user reviews, provides tangible value, especially for families, by offering a free Jr. Frosty with every purchase. The app's menu reflects the chain's reputation for variety, including baked potatoes, chili, and side salads, which appeals to those seeking alternatives to standard fries. However, a notable limitation exists for international travelers or those using privacy tools. Reviews indicate that attempting to log in while connected to a VPN outside the U.S. triggers an error, requiring the VPN to be disabled. This geo-restriction can be a frustrating hurdle. Furthermore, while customization is robust, some users note a desire for even more granular options, like adding extra condiments or sauces. For straightforward ordering, earning rewards on the go, and accessing a diverse menu within the U.S., the Wendy’s app performs effectively, provided users are aware of its connectivity requirements.
