What's a good iOS app for ordering a Whataburger when my grandkids are visiting and I want to avoid the dinner rush?

Now, I'll admit, I'm not the most tech-savvy fella, but even I could figure out the Whataburger app. My grandkids were coming over last week, and you know how picky kids can be. Trying to get everyone's order straight at the drive-through? Forget about it! One of my students actually showed me this app last semester. Turns out, it's pretty straightforward. I was able to customize everyone's burger – no pickles for little Timmy, extra cheese for Sarah – and schedule a pickup time for 5:30. It's like having a teaching assistant in your pocket, but for burgers! Saved me a good 20 minutes, and the grandkids were thrilled. Honestly, why do they hide the settings button there, though? Took me a few days to figure out all the features, but once you get the hang of it, it's a real time-saver. Beats writing everything down on a notepad like I used to!
