JLPT N4 Vocab (Japanese words on the Lock-screen)

Hey. Why now when i closed apps, the lock screen learning is also closed? I think before this the lock screen learning will comes each time I sleep my phone or even reboot. It is the best feature of this apps to have lock screen learning!

Good interface with multiple ways to study plenty of words on the go. Unfortunately some of the word definitions range from vague, not entirely correct, or only using one definition of the word. For example omiyage is normally used as souvenir but instead is used as present (and in the same set as プレゼント -present). Or in the sample pics the word いらっしゃる is to come but it really is the humble expression of iru/kuru/iku or to be/to come/to go. I'm still going to use this app and the accompanying jlpt2+1 but I definitely feel my vocab is going to have major holes.

After the latest update, I cannot access the app, it just keeps loading forever with the Please wait screen. Please fix. Also, I want to know how many words are in this app. Thanks

love it
