What's the best Android app for ordering drive-in food while getting half-price drinks?

SONIC Drive is designed for customers who want to skip the speaker box and order their food and drinks directly from their phone for pickup at the drive-in. The app's primary strength lies in its streamlined ordering process, which recent updates have significantly improved. Users report that previous frustrations with location detection and a slow checkout have been resolved, making it much quicker to place an order for items like the chain's popular slushes and cream slush drinks. A key feature for many is access to promotional offers, such as half-price drinks during Happy Hour. However, it's important to note that these deals are no longer applied automatically; they must be manually redeemed from the 'Offers' section within the app before checkout, which some find to be an extra step. For pickup, the app provides a check-in button to alert the carhop. Occasional glitches, like a stall showing as unavailable, are reported, but users typically navigate this by simply pushing the call button upon arrival. The app also supports Sonic's rewards program, allowing points accumulation on purchases. While the interface is generally reliable for standard orders, some users have noted a desire for a more robust custom order option to handle specific modifications, like adding extra toppings or removing ingredients, beyond the standard menu buttons.
