Good Support for HSK 3.0
HSK Tracker has good support for its product. For now until i know more about the app. I will give it a good review.
Response from developer
Dear user, thank you for your feedback. The character "绳" you mentioned is included in HSK 2.0, which you can access by switching to the HSK 2.0 list in the app. In HSK 3.0, it belongs to Levels 7-9 (not yet available in the app). Our 5,000+ words are all from the official HSK lists provided by chinesetest.cn. Hope this helps!
incomplete HSK 3.0
Does not have all the HSK level 5 characters just testing app and looking up characters finding 2 already that are not in the list. I cant trust this app if i find characters that are in the HSK 1 - 6 but not in this app.
