Mast is a beautiful Mastodon 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.

I'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! I hope you enjoy using Mast.


“What is Mastodon?”, 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.


If you're a fan of details, here's what Mast contains:

- Beautiful and clean interface
- Fast and lightweight
- Light mode (day), dark mode (dusk), darker mode (night), true black dark mode (midnight), and midnight blue themes (you could even set up Siri Shortcuts to do this for you magically)

- Polls support (create, view, vote)
- Supercharged media viewer and Picture-in-Picture videos that can be dragged around

- Swipe actions to like/boost/reply (swipe right)
- Swipe actions to mute/block/report/translate/share (swipe left)
- Alt image text addition and viewing support
- Pinch the screen anywhere to toot a screenshot
- Schedule toots for the future
- Filter toots
- Endorse accounts

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!

Crashes on iPad, notifications broken on iPhone

The app looks great! Best UI in all of the Mastodon apps I have tried. Unfortunately, the app constantly keeps crashing on my iPad (non-Pro) 2018. Logs in fine, but the moment I touched on the hamburger menu icon, it crashed. Upon reopening the app, my feed is blank. No way to get my feed back without reinstalling the app, but the hamburger menu crash still persists.

The app itself works fine on my iPhone 8+, fortunately. But, there is a weird issue with notifications. They show up in the Notification Center on my phone just fine, but they do not show up on the app. I’ve tried to manually sync them, but new ones will not show up. Only notifications that I had at the time I logged in. Logging out and back in again makes newer notifications appear, but this is not ideal.

Developer Response ,

Hey, thank you for the great feedback and insight into what's not working as great as it could be. The iPad app will be redesigned entirely from the ground up in the near future and will contain fixes and better handling of elements. The feed issue should also be fixed for the next update where it refuses to load sometimes. In terms of notifications, this is now resolved for the next update too. Hope this helps!

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.
