Mastodon is the best way to keep up with what’s happening. Follow anyone across the fediverse and see it all in chronological order. No algorithms, ads, or clickbait in sight. This is the official iOS app for Mastodon. In our app, you can: EXPLORE ■ Discover new writers, journalists, artists, photographers, scientists and more ■ See what’s happening in the world READ ■ Keep up with people you care about in a chronological feed with no interruptions ■ Follow hashtags to keep up with specific topics in real time CREATE ■ Post to your followers or the whole world, with polls, high quality images and videos ■ Participate in interesting conversations with other people CURATE ■ Create lists of people to never miss a post ■ Filter words or phrases to control what you do and don’t want to see AND MORE! ■ Login and switch between multiple accounts ■ No spoilers! You can put your posts behind content warnings A POWERFUL PUBLISHING PLATFORM You no longer have to try and appease an opaque algorithm that decides if your friends are going to see what you posted. If they follow you, they’ll see it. If you publish it to the open web, it’s accessible on the open web. You can safely share links to Mastodon in the knowledge that anyone will be able to read them without logging in. Between threads, polls, high quality images, videos, audio, and content warnings, Mastodon offers plenty of ways to express yourself in a way that suits you. A POWERFUL READING PLATFORM We don’t need to show you ads, so we don’t need to keep you in our app. Mastodon has the richest selection of 3rd party apps and integrations so you can choose the experience that fits you best. Thanks to the chronological home feed, it’s easy to tell when you’ve caught up on all updates and can move on to something else. No need to worry that a misclick will ruin your recommendations forever. We don’t guess what you want to see, we let you control it. PROTOCOLS, NOT PLATFORMS Mastodon is not like a traditional social media platform, but is built on a decentralized protocol. You can sign up on our official server, or choose a 3rd party to host your data and moderate your experience. Thanks to the common protocol, no matter what you choose, you can communicate seamlessly with people on other Mastodon servers. But there’s more: With just one account, you can communicate with people from other fediverse platforms. Not happy with your choice? You can always switch to a different Mastodon server while taking your followers with you. For advanced users, you can even host your data on your own infrastructure, since Mastodon is open-source. NON-PROFIT IN NATURE Mastodon is a registered non-profit in the US and Germany. We are not motivated by extracting monetary value from the platform, but by what’s best for the platform. AS FEATURED IN: TIME, Forbes, Wired, The Guardian, CNN, The Verge, TechCrunch, Financial Times, Gizmodo, PCMAG.com, and more.

Verdict
The clearest difference is ratings volume: Mastodon at 13K against Shut Up's 49. Mastodon also leads on update cadence (monthly vs every 6 months) and rating (4.5 vs 4.2). Shut Up's advantage is device support (4 vs 2) and iOS requirement (12.0 vs 18.6). On price, review sentiment, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Mastodon holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: Mastodon has 13K ratings behind it against 49, so its average is the more settled of the two. Written reviews complicate that: 56% of Shut Up's written reviews are positive against 48% of Mastodon's, so the app with the better star average is not the one people write more warmly about.
Shut Up ships an update every 6 months, Mastodon monthly. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
