Works again; updating my review
App version 0.7.3 was broken, but 0.7.4 works again. It still needs a lot of work now that it supports chat, though. Basic things are broken, such as getting trapped in the Settings menu and having to force close and relaunch the app. It only supports a history of 100 chat messages total per account, with no ability to pay for more nor pin the content yourself. The rough interface could also use a dark mode option... plus you have to provide encryption keys to it from a QR code that you generate on a desktop app, which feels very unsafe. If the app wasn't open source and working to solve important gaps in Ethereum mainstream usability, I would have deleted it. It feels like a technical demonstration, but I admire them for trying to help improve Ethereum.
