### 1/5 — App suks

*2022-11-23, version V 1.2.1*

App is useless!

**Developer response:** Thanks for the feedback. With a little more detailed feedback, we could continue to work on the app. Feel free to get in touch with our support.

### 1/5 — Horrible

*2019-02-05, version V 1.1.3*

I don’t understand how request after request had fallen on deaf ears. This app does not work on iPhone or iPad. I have tried multiple phones and iPads and none have worked. What did I pay top dollar for the analyzer for it to sit and lose value?
