h3poteto, the username of a software engineer from Japan that only goes by the name* of the fictional character Akira Fukushima online:
Recently I started Mastodon. I can find some nice client applications in iOS and Android, but I could not find client for desktop application.
The above from a post on Medium from March of last year describes why h3poteto started building Whalebird. Well, they've kept up development and I'm now using build 2.6.1 on Windows and it is quite good. It is far better than most other clients I've used.
* When I take 10 or so minutes trying to find someone's real name online and I'm unable to, I take that as a sign that this person would rather me not know so I stop digging.
