### 1/5 — Recommended but no instructions

*2023-11-10*

I opened this app but can’t make sense of it. I have no understanding of how to use it. 
I got it because it was recommended. But it’s so secure I don’t understand it. 
I looked at the contact the developer button but there is nothing to help there either. 
Puzzled.
