Ah, Adam Neely! I saw this vid pop up in search results yesterday, but somehow I don’t like his videos… I really don’t know why, he’s seems like a super nice guy, astonishing knowledge of music, great conent… I guess the way he presents his stuff just doesn’t jibe with me. But I will watch this during my breakfast break!
For eartraining I use a phone app called Complete Ear Trainer. Not free, they ask a few dollars for it. I had Earmaster on my PC. Liked it but wanted someting for my Android phone and this is what I settled for. It’s mainly for convenience: I can use it while havin’t lunch, waiting in the car, squatting… And the app doesn’t let you peek ahead, you have to achieve a certain score to be able to advance to next chapters.
