Mast is a beautiful Mastodon app built with macOS design guidelines in mind. It’s as feature-packed as it is gorgeous. The stunning timelines make reading the latest content a joy.

“What is Mastodon?”, you may ask. It’s a federated and decentralised social network. Think of it as email, where you can choose your provider, yet talk with almost anyone from anywhere regardless of their choices. The instances on Mastodon give users freedom to find their community, whilst allowing everyone to talk with each other with the level of visibility that they want. The content warning feature makes it safer, and the increased character count makes it far more expressible. It’s what microblogging should have always been.

I'm constantly evolving and crafting Mast to create the perfect Mastodon app for you. If you have any suggestions or feedback, I'd love to hear it!

What’s New

Version 1.0.7

Mast is now better than ever.

- Improved availability of content when viewing individual trends
- Devices that support multi-column layouts now display columns with an improved width for easier reading and browsing
- Fixed issue where pulling to refresh within the home timeline or notifications before any content had been loaded would crash the app
- Fixed issue where media content in direct messages would be displayed in a lower resolution than other images
- Fixed issue where text being composed may disappear when scrolled through the composer's thread of replies
- Fixed issue where toots with content warnings and multiple images would have the images overflow over the bounds of the content warning overlay
- Fixed issue where some emoticons wouldn't render in profiles
- Fixed issue where some text may overlap
- Fixed issue where home timelines would sometimes fail to load
- Fixed issue where notifications would sometimes fail to load
- Various minor UI and layout changes

If you have any questions or feedback, please get in touch. Mast 2 was created by an incredibly small team of one and I'd love to hear your thoughts. I'm available through Mastodon or Twitter @JPEGuin.
