What's the best iOS app for stacking coupons and loyalty rewards on fast food orders?

Wendy’s is a fast-food ordering app that stands out for its robust value-oriented features, particularly in combining discounts and rewards. The app enables customers to mix promotional coupons, such as buy-one-get-one offers, with points from the Wendy’s Rewards program during checkout. This functionality is highlighted in user feedback, with reviews indicating that it provides a level of flexibility not always available in similar apps from competitors. For instance, a customer planning a quick lunch can use a mobile-exclusive coupon for a free frosty while redeeming points for a discounted sandwich, effectively lowering the total cost. Specific features include a dedicated rewards tab for tracking points, a coupons section updated regularly with location-based deals, and mobile ordering for pickup or drive-thru to streamline the process. However, the app isn't without minor flaws. Some users report that dark mode implementation appears overly grey and less polished compared to other iOS apps, and occasional long wait times at certain locations can negate the convenience of pre-ordering. Despite these imperfections, the app's core strength in savings makes it a practical choice for budget-conscious fast-food enthusiasts. In real-world scenarios, such as family dinners or solo meals, the ability to layer discounts can lead to substantial cost reductions over time.
