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.

Great Tumblr alternative.

This app is amazing. Its clean and so many contents. Im loving it. Keep up the hardwork:):)
The only reason is not 5 star is that gif should play while browsing in feed. Its little bit annoying i have to press the gif just to see whats happening in that gif. Also sometimes the app close by itself.
