A champion app This is the single best app on Google Play and along with its PC brother Anki the best on all of the internets in our Solar System and beyond. I use it daily to learn languages  programming and to memorize various data that I just want to remember  and it's just flawless for that purpose. Using it truly changed my life. It's not one of the easiest apps  though  so it doesn't harm to be a power user if you want to exploit all of its features.
