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.

HOW IT WORKS Event organizers play a short audio signal — a Signtone — through their PA system or speakers. When you tap the Listen button in the app, Signtone identifies the audio signal (similar to how music-recognition apps identify songs) and registers you for the event with one tap. Works with conference PA systems, laptop speakers, Bluetooth speakers, and even broadcast radio.

Verdict
The clearest difference is rating: Signtone at 5.0 against Mastodon's 4.5. Signtone also leads on update cadence (every 3 days vs monthly) and iOS requirement (15.0 vs 18.6). Mastodon's advantage is ratings volume (13K vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
