I've kind of got stuck at a lower-intermediate level of Korean.... maybe that's because I haven't been around here at Italki much lately? :)
But I did get married to a Korean lady, so I don't think that's the problem!
I think one of the main reasons is that I struggle to remember 'advanced' words that I don't use every day.
A lot of these words are based around 한자 - and I've heard that learning the 한자 will really help with learning vocabulary.
Of course I don't really have time to learn 한자 well! So I made a little Android app that would help me remember the 한자 meanings in each of the words:

It's free (I just want to help, not make money!) and won't ask for any permissions on your phone - just something to help me out, but I hope some other learners might be interested too.
What do you think of this idea? Is it useful for studying 한자어 vocabulary?
