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

Mast is also fully optimised for iOS 13 with dark mode and context menu support. It also has Today Extensions, Share Extensions, iMessage Stickers, a Watch app, Siri Shortcuts, and an iPad app. I hope you enjoy using Mast.

“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!

What’s New

Version 2.1.0

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.

Very unstable

Every five minutes the app would just close down unexpectedly. Even just searching hashtags will just close down the app. For a premium paid app, I’d expect something stable at least. Crashes i can handle but when it starts to impact workflow, then it’s something i cannot ignore.

Update 1.7 App still struggles to maintain its uptime and bugs persist. I am not going to seek to use this anymore and will find an alternative app thats stable.

I'm sorry for this experience that you've encountered. Most of these issues should be resolved with the latest update now (1.7.0).

Not very good

Unfortunately I think I may have wasted my money with this purchase. The UI is ok, albeit very childish with its confetti every time you interact with the app, and larger than life icons. But what really frustrated me was the lack of customisation, yes you can change the theme and even the icon, but the dev should have taken care of the core stuff first. You can’t customise the feeds you see, or how many. Also when refreshing, I just get a few new toots, so if I’ve been away for a few days, I have to refresh multiple time (like 20) to get to the top of the feed.

If changing the theme and having confetti pop every time you post is important to you, then buy this app. However, if actual usability is, I’d probably stay away for the time being.

Thank you for expressing your concerns regarding Mast. We have the option to disable the confetti via the settings section (which you’ve suggested there aren’t enough of - you can change almost every aspect of the app that can be changed according to the Mastodon network). The app may seem childish, and the fun/bubbly look is exactly what I was going for, which the plethora of screenshots and app videos already demonstrate. Toot loading is down to how Mastodon handles it, as it can only fetch 20 at a time, a limitation that we don’t like either. I appreciate that this app isn’t to your liking, I’m sorry about that, but there’s nothing there that wasn’t already conveyed across in the App Store details and screenshots. Thank you.

Pretty good.

Visually this is great, and there are lots of customisation options.

I’ve experienced a few crashes, and there are usability improvements needed in places - for example when viewing another instances timeline you should have the option of doing so with your primary account, at the moment it just fails - but it’s a good start and I’m happy to buy it to support the developer.

Developer Response ,

Thank you for the support! Most of the crashes are getting fixed progressively, hold tight. :)
