What's a good iOS app for a guy like me, who's not getting any younger, to eat healthier without having to spend all evening cooking after teaching?

Let me tell you, after grading papers all day, the last thing I want to do is cook a healthy meal. My students actually showed me this app, Factor, and it's been a game changer. It took me a few days to figure out all the options on the app – why do they hide the settings button there? – but once you get the hang of it, it's pretty straightforward. You pick your meals for the week, and they arrive ready to heat up. It's like having a teaching assistant in your pocket, but for dinner! I'm eating better, and I'm not spending hours in the kitchen. Plus, the app keeps track of what I've ordered, so I can easily reorder my favorites. Makes you feel like you're taking care of yourself a bit better, which is important at my age.
