I do! My method so far has been: HelloChinese - At the time that I first downloaded this app they were revamping their course and making it so that after you reach a certain point you have to pay to continue using it BUT they still had their old course available which was completely free and goes all the way up to HSK3. So after I completed all the free content in their new course I went back and did everything from their old one as well. I went through the lessons pretty quickly since I did like, one unit per day (which is around 3 or 4 lessons), so it only took me a few months to 100% it, although I kept doing reviews for a while after that as well. I'm not sure if they still have their old course up or not, but I was able to access it cause I have an Android and so just went through their app version logs and downloaded the APK where the old course was still available. DuChinese - This is one that you can do in tandem with HelloChinese, because reading these short stories really boosts your comprehension of what you're learning and makes it stick way better than just pure memorization. After I finished HelloChinese I felt kind of lost for a while and so clung to DuChinese like a lifeline lol. Only downside is that they only have a certain amount of free content at a time, and while they do rotate it so that every week some different content becomes free for a few days so you don't run out of stuff to read, it's still only a handful at a time. Hanly - this one's a more tentative rec because I personally found it helpful for recognizing characters easier since it includes mnemonics for each character, but for the visuals they use AI for all the backgrounds that they have on the cards... there is a setting where you can turn them off but I keep them on since they help me visualize the word meaning better. NinchaneseGrammar - Ninchanese does have their own regular Mandarin app but tbh I don't like it very much, I only use their grammar-specific app, and recently they overhauled it so that it's more 'gamified' so you can do practice drills with different grammar patterns. Youtube - I took one of my old youtube accounts that I don't use anymore and completely scraped it clean, subscribed to only my favourite chinese channels, and refuse to click on anything unrelated on that account to make sure my feed stays relevant. From my expereince, doing it this way is much more effective at finding good/new content than using your regular youtube account, because then your feed isn't trying to juggle several of your interests at once. (Lmk if you want some recs of good channels to start with!) Readibu - Good for reading practice, grabs both from websites that specialize in children's stories and regular webnovel sites, and when you open it in the reader you can use the pop-up dictionary to quickly look up words/pronunciation for characters you don't recognize

This is everything I did app-wise, but I'm also in a Chinese learning discord where I chat in Mandarin and receive feedback on other stuff I do. Getting feedback and having my specific questions answered has been the biggest thing for me, lets me know in real time what I'm doing wrong and how to fix it :)
