### 1/5 — Poor design

*2020-10-26*

The combination of white letters on a light blue background is a total disaster. Have to strain the eyes to see anything on the screen. That combined with a tiny font size makes using this app very difficult.

### 2/5 — RUE

*2018-08-06*

Wasted a lot of precious time!!!  Followed the instructions but could not scan the QR code from the application I was using and could not figure out how to enter a shared secret.  Tried repeatedly but couldn’t get it the QR Code to scan and no instructions available regarding shared secrets.
