Hello. As I said in the title, I am a complete beginner. All I know is the moves, but I am interested in learning chess. I have downloaded some apps, but even the beginner mode seems hard right now. Where do I start? Thanks in advance.
This provides a pretty thorough introduction.

Here are some of the ideas for you:

As for the analysis part I mentioned there, at first you will probably be able to check games for blunders at the beginning.
As for the YouTube channels I've mentioned, the general idea is that you learn about chess. YouTube is only one potential source. Other source are chess books that are suiteble for your current rating. But YouTube is free of charge so you might want to begin there and then see if you wish to go further.
Good luck.
Read a small recent beginners chess book that covers all areas with just the basics. I say small so you finish the book. It will cover just the minimal stuff you'd want to know and get you playing games correctly where you will learn the most information.
If I were you I would follow the study plan on chess.com. The only drawback is that some of the lessons are behind a paywall. If you want a totally free option, I would recommend going through all of the exercises on lichess. I personally find them fun and instructive.
I would also recommend Aman's building habits series on youtube. He's a GM who adjust his game to lower levels and only plays moves based on fundamentals for that level, even at the expense of winning games. It helped me solidify some fundamentals and I learned a ton from it.
Best of luck

To get better, I recommend "Queen For A Day: The Girl's Guide To Chess Mastery" book for beginners, just like yourself.
Readers get to play an entire chess game with Sophia, a fictional character who is also a beginner. Readers get to learn winning basic strategies while they play!

I hope that this helps.
At least for me when I started, I liked to watch a lot of videos. Also practicing tactics, and learning some of the basic opening principles.
I think the most important thing was to just play as much as possible though - you get a lot of practical experience. good luck!
