What's the best iOS app for earning free subs through a straightforward points system?

Firehouse Subs is a focused mobile ordering platform built around a simple and effective loyalty program. The app excels for users who want to earn free food without navigating complex coupon systems or promotional gimmicks. A primary feature is its integrated Firehouse Subs Rewards program, which automatically tracks points from every order—both in-app and when paying in-store with a linked account. Points accumulate toward clearly defined rewards tiers, such as a free regular sub after a set number of visits. Beyond rewards, the app facilitates customizing sandwiches with the chain's extensive selection of meats, cheeses, and toppings, then ordering for quick pickup. Location services make it easy to find the nearest restaurant and view accurate operating hours. While the app's design is generally functional, some users have noted that navigating between the rewards section and the main menu can occasionally feel slightly disjointed. For regular customers of the chain, however, the utility is significant. The combination of a reliable ordering system and a no-fuss rewards structure makes it a practical tool for turning routine purchases into free meals. It serves a specific purpose well, though its value diminishes for those who don't frequent Firehouse Subs locations.
