This is very astute and I think things like this app are probably actually counterproductive for this reason--if we imply learning to cook is comparable to learning a _language_ in its complexity you're only going to make people more wary. Really all you need to do is buy ingredients and follow a recipe; now you're cooking! It isn't that hard.
As you say, the real learning process of cooking involves making things, getting a sense for what works, what you like, and iterating, and you can't really get this from an app, or videos, or whatever.
Let's take your other comment: "just buy ingredients and follow a recipe". This makes no sense to me. Sure, I could just make the 10-20 guesses required to buy ingredients & get to the end of the recipe, it would probably result in something edible but bad. At that point, I'll have learned how to make it better next time, but not necessarily how to make it half-decent.
So, as OP describes elsewhere, whenever I'm trying to follow a new recipe, I end up looking up an average of 5 vids on prep or technique that I'm unsure about. It gets me something half-decent in the end, but it's a lot of work, and I never feel like I really "get it".
Also, your overall tone is so weird to me. You're talking about cooking like it has no fundamentals and it's just loosey-goosey & based on people's preferences, but there are DEFINITELY wrong ways to cook things, and lots of them. I learn more about those wrong ways every time I try cooking.
If you want a recommendation, I highly recommend Laura Vitale's YouTube channel. She helped us get brave enough to do it. I use her recipes all the time (take your pick - it'll be good. The recent "one pan orzo chicken" is already a staple around here), and her videos really show her making the meal. So when you're making it yourself, you really feel like you've seen everything before :)
good luck on your cooking journey!
Scrambled eggs are a good thing to learn for a beginner, and maybe the app does try to teach you the real "hard" part of them: Heat control. If you understand the heat of your stove and your pan, you can make scrambled eggs.
You can learn it by getting a carton of eggs, a stick of butter, and a frying pan. You'll learn how butter burns and gets too hot, and you'll learn when you jump the gun and put the egg in too cold of a pan.
People want steps and skills and tricks. But the real way to learn how to cook is to look at & listen to your pan, taste your food, and then repeat and learn from your mistakes.
