Great app, some issues
With that said, this app has some issues.
1) The analyzer stopped working for me. Every time I’ve tried to use it in the last day or so, it’s failed, meaning I can no longer mark what words I don’t know. This defeats the whole purpose of the app.
2) The sentences also frequently contain vocab that is way beyond the selected level. For example, in level 2 texts, I will often get more than one word that is HSK 3.0 level 5-7. This again defeats the purpose of the app, because now I have 3-5 unknown words per 1-2 sentences, and those words are often way higher level than I want/need.
3) You can’t keep your progress if you down level. When I did this, my learning was basically reset.
