App not downloading, not on Itunes anymore

My iPhone saved dumped the Hello HSK1,2,3 from my phone because they hadn't been used recently enough.

Now when I go to use it, I get an error messaging saying the "App is no longer available from the app store" anyone else have this issue?

Same issue for me. It says item not available on Apple store.
