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.

(Requires a Mastodon account)

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!

Best one I’ve tried yet.

A few things I’d like to see added and would tip to see: 1. ability to swipe between home/local/all rather than reach up to tap. 2. option to see # of replies/boosts/fave on posts without tapping toot. 3. ability to add hashtags to follow via home after searching them like you can on web. Least to most important IMO ^

Accessibility is an afterthought

I want to like Mast, but when the rough edges for the app do appear, they’re usually in accessibility features. When I upload a photo to include in a toot, for example, there’s no obvious way to add a caption for screen reader users. I have to somehow know ahead of time to long-press the uploaded image, and even though it says it’s done uploading, I get an error when I try adding a caption saying I need to wait until it’s done uploading, even though I haven’t published the toot yet and the app already showed that the image was uploaded. This doesn’t work even when I save it as a draft, because when you do that it doesn’t save the image with the draft and you have to re-upload it and run into the same error. They got a good dark theme though, but that just reflects the priorities of the app.

This app is great and has what it needs as a mobile version of mastodon. There are some bugs that aren't so great, one in particular is that I'll try and post a finished toot, but in the process the tab closes and I lose the whole toot. It doesn't save into my drafts, simply just deleted when it was meant to be posted. This aside, I really enjoy the app, thanks guys!
