You made me curious so I tried this app. Unfortunately the UI is horendous. So far I tried the macOS, iOS, .jar and web version. Each version generates different passwords for the same site. This app has the most confusing UI I have seen in a long time, with each version being wildly different from the other. I still have no idea how to have multiple users for the same site, or even if setting the user makes a difference at all (seems not as it does not change the password). But most important: this app generates different passwords for the same input on different platforms. Kind of beats the purpose of having it in the first place.
