### 1/5 — App crashes cannot even use

*2019-12-05, version 1.4*

Probably the worst backend design. Does not even work! Crashes in every possible way. Be careful when press any button, because it may crash the app. Do you test your code ever before put out?

### 1/5 — Mr. Up

*2019-07-22, version 1.3*

Says the language is English. The entire app and all functions are 100% Japanese.
