Mast is a beautiful Mastodon and Pleroma app built with iOS design guidelines in mind. It’s as feature-packed as it is gorgeous. With customisable content and themes, it’s most definitely the perfect choice.

The stunning timelines make reading the latest content a joy, and tapping the on-screen elements gives you a wonderful haptic response. Long-holding anywhere in the app quickly lets you toggle themes, and Siri Shortcuts let you do the same, and more. Awesome.

We’ve also thrown in some cool things like 3D Touch support, Today Extension, Share Extensions, iMessage Stickers, a Watch app, Siri Shortcuts, and an iPad app! We hope you enjoy using Mast.

“What is Mastodon/Pleroma?”, you may ask. Well, 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 and Pleroma 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.

Very promising, pleasant to use, minor snags yet

I've been using Mast for a few days so far, and it's been quite great! The interface feels well thought out and behaves as I'd expect it to. It supports the Mastodon features you need (message privacy, CW's, sensitivity and textual descriptions for pictures), and feels pleasant and fast.

Some toothing problems in this revision, but I expect they'll get fixed soon!

* the "activity" view crashes very often
* you can use the app one handed! Great when waiting in line: double-tap images to zoom, throw them away to dismiss; unfortunately, dismissing animated GIFs requires stretching your thumb all the way to the X in the far left corner (Mast does picture in picture, which seems neat but I don't use it)
* It still loses scroll state on occasion (but is pretty good at retaining the position usually!)
* content-warning posts, once revealed, can't be closed again; the only way I found to do that has been to scroll away, which restores the warning (weirdly: I've seen background refreshes restore the content warning without any interaction from me)

Overall, I think this app is more than worth the price! Once the crasher bugs are fixed, I'd absolutely recommend using it for anyone's Mastodon needs!

Room for Improvement

Mast definitely is still my favorite Mastodon third party client despite its crashes and flaws. There are a lot of things that needs improvement. Developers make mistakes. It is called being human. I will give this developer a chance before I decide to move on.

Now, the crashes takes place when I tap on 1) my avatar icon and 2) the timelines list. Second, there is an issue with changing my profile photo. Third, the settings has become increasingly crowded with lots of customization options that is becoming a bit of headache for me due to the lack of organization and proper sorting. This can be solved by displaying a list view of the main category first instead of showing everything (e.g. app icon, appearance, general, security, about) or a “show more” button and “show less” if you are lazy.

Good luck and all the best JPEG!

Better than the webUI, work in progress

I’m giving Mast 5 stars because this app is beautiful to look at (though uniquely designed it’s still easily navigated) and the potential is there to be the go to app for Mastodon users.

I can’t stress this enough: If you need a mature app that’s been tested for years and has a solid bedrock of Q&A underneath it: look elsewhere. Part of Mast’s charm is that it’s immature software and although it’s a bit buggy, the developer works incredibly hard on adding features and squashing bugs. Updates are frequent and I haven’t witnessed any update feel like a “regression”

I’m happy I bought it and look forward to future updates.
