ChordProg Lite - Ear Training

After years of playing gigs I've just recently started ear training, but all of the apps I tried for chord progressions were too easy. They literally just played a series of chords in root position, so even someone with less than a year of playing experience with no specific theory knowledge could figure out the answers. It's nice to finally have a system that allows for context and real applications of chord progressions. I can't wait for more chords to be added, and maybe different voice leadings. Also, progressions in minor keys. Also, the app doesn't work on my Samsung Galaxy S III with CyanogenMod 12.1 so I have to use BlueStacks. Not a huge deal but would be nice to be able to use on my phone.

This is definitely a huge step in the right direction. In fact, it's almost all the way there. But what I wish you'd add to it is a way to have a large series of sequences like this chosen randomly, just for never-ending practice without the game format. If I'm correct, anytime you go to, say, Level 5, all the sequences from that level are played back in the identical order. If the sequences were chosen at random within levels, there'd be a greater sense that you weren't going to run out of material.
