What a dainty little app with a little bit of everything for day to day learning! :embarrassed:
I know a lot of people that can testify to memrise - it's quite good for a free community-run language app. The kanji can get a bit touch and go at times though...
Just a tip: I've found it easier to learn those characters as separate entities entirely (and what they represent), and for the radicals that they are comprised of.
Some symbols are definitely more used than others, so that helps, i guess.
Good luck with the studies!
