You can use them interchangeably. I have the modded game on an old tablet and the vanilla game on my phone. If I encounter a glitch in the modded game and I can't get around it, I save my game, close the app, and play through that section using the vanilla game on my phone. As long as you remember to go into the options menu and save your game often, the saves will be synced up between all of your devices. The game has an autosave function too, but it's not reliable.
I don't know any Spanish, but you can use
DeepL to translate this text into your native language. It's much better than Google Translate.
