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.

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.

Signtone is the fastest way to check in to events. No QR codes. No NFC tags. No typing names into forms. Open the app, tap Listen, and the event is identified. 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. ATTENDEES - Tap Listen to identify the event you're attending - Register with one tap — your profile is shared instantly - Choose between a public or a professional (LinkedIn) profile - Access event resources, links, and handouts right on your phone - View your registration history anytime EVENT ORGANIZERS - Create events and generate Signtone audio from the dashboard - Upload banners and resource links for attendees - Track registrations in real time - Export attendee lists as CSV - Run sweepstakes and prize draws - Works for conferences, meetups, trade shows, and retail events TWO AUDIO MODES Universal: High-frequency signal (16.5-17.5 kHz) — works without disrupting conferences Broadcast: Audible signal (1.2-3.8 kHz) — works over radio, PA systems, and noisy environments PRIVACY FIRST - Audio is processed solely to identify event signals - Audio is not recorded, stored, or used for any other purpose - You control which profile to share at each event - Microphone access can be revoked anytime in iOS Settings Signtone — Hear it.
