Those are all useful tools, especially if you personally enjoy learning from apps. Enjoyment is key. But one glaring hole is that it’s missing engagement with written or spoken input. Without immersing yourself to some extent in written or spoken content, your comprehension will suffer. It’s all well and good knowing all the conjugations and stuff, but if you can’t understand a word people are saying because you haven’t practiced listening enough, it will be frustrating.

If had to suggest something, I’d start engaging reading as much as you can. I started off with very basic mini stories such as the ones I found on www.thespanishexperiment.com. I then picked up Olly Richards’ Short Stories For Beginners when I was A1. They’re written for A2-B1 but I just about managed, and now a few weeks later I’m flying through it pretty easily. I would incorporate the Duolingo Spanish podcast. Again, intended for intermediate learners but you can listen along with the transcript and pause to give yourself time to read when needed. In short, I would think that reading short mini story or listening to even just half of a duolingo podcast (I.e. 10 mins) would be way more valuable than the duolingo lesson.
