Authy is one of the worst-designed iOS applications I have ever used. It has been this way for a very long time. They are actively hostile to people who try to criticize their poor design choices. I would not classify it as "dedicated to excellence."
CloudFlare forces me to keep it installed, so I have to interact with it on occasion. If you have more than about 3 services set up, you have to first scroll to expand the scrolling list of icons, then scroll multiple times to find and read the 10pt font name of a service, etc. It's awful. Compare it to Google Authenticator, which has a nice, big scrolling list of numbers and names. The one advantage Authy has is encrypted backup, which I like, and service lock-in, which annoys me.
Perhaps there's hope in somebody else taking over. Please, Twilio: prioritize _usability_.
