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.

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?”, 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 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 500 character count makes it far more expressible. It’s what microblogging should have always been.

We’re constantly evolving and crafting Mast to create the perfect Mastodon app for you. If you have any suggestions or feedback, we’d love to hear it! Come visit us on Mastodon or our Twitter page, and let’s craft an incredible toot browsing experience together.

What's New

Version 1.2.3

Is it pronounced GIF or GIF? Either way, you can now search for the perfect one to respond with. Happy days.

- Added the ability to browse and add GIFs to toots when composing
- Added the ability to view profile header images by tapping the header
- Improved custom emoticons rendering
- Fixed issue where images wouldn't upload via the Share Extension
- Fixed crash when interacting with toots from other instances
- Fixed issue where you couldn't log out via the iPad app
- Fixed issue where profile actions would take a while to load

Mast never prompts you for a review because we believe browsing your timeline should be a distraction-free experience. If you feel generous and have some time to spare, please consider leaving a review. It helps more than you can imagine. Thank you! :)

Ratings and Reviews


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. :)

Style AND substance, wow!

It’s not often that I come across an application that is both extremely functional and easy-to-use whilst also being drop-dead gorgeous, but Mast has accomplished this!

It’s literally thanks to Mast that I made my Mastodon account. Congratulations on a job, excellently-done!
