I really need a good app to learn

Hello people! So, at this moment i can speak two languages, my first language (Spain) and i’ve learned english through my whole life. So now i’m interested in learning deutsch again (because i studied it in highschool but i forgot almost everything) and french. My problem is there are a TON of options in the App Store to learn. I’m currently using Duolingo with deutsch (which is helping a Lot) and Memrise for french. My problem is that Memrise is awful to me, i’m trying to learn new words and expressions and the app force me to do shitty AI generated content. What free app should i use? I have no intent to have an official title, i just want to learn in short/medium seasons just in case i travel to those places. I used Busuu a lot and that’s the best app i’ve ever tried, it’s the closest to a proffesional course. Hope i’m asking in the right sub, if not, sorry for the inconvinience
