Dyno is a free, secure, and fun messaging app built for people who want more personality in their private conversations. Send messages, voice notes, and Dyno-themed reactions. All encrypted and completely free, with no ads ever.

SECURE
Your privacy is our priority. Dyno uses server-side encryption to keep your messages protected. Your private chats stay between you and your contacts, nobody outside your conversation can access what you share inside it. Group conversations are fully private and visible only to members of that group. Your data is never sold, never shared with advertisers, and never used to build a profile on you.

PRIVATE MESSAGES
Every one-on-one conversation on Dyno is private by design. Your messages are encrypted and securely stored - accessible only by you and the person you are messaging. Start a conversation knowing that what you share stays where it belongs.

GROUP CHATS
Bring your whole herd together. Create group chats for friends, family, your team, or your community. Group conversations are fully private - only members of the group
can see what is shared inside it. Coordinate, connect, and keep everyone in the loop, all in one place.

VOICE MESSAGES
Sometimes text is not enough. Record and send voice messages instantly - perfect for sharing your tone, your energy, or a quick update without typing a word. Voice messages are delivered quickly and securely, just like any other message on Dyno.

DYNO REACTIONS
Express yourself the Dyno way. Send animated dinosaur-themed reactions. Dyno reactions make every conversation more fun and more personal.

MULTI-DEVICE
Start a conversation on your iPhone and pick it up on another device without missing a beat. Dyno keeps your messages securely synced across your devices so you are always connected wherever you are.

FREE. NO ADS. NO TRICKS.
Dyno is completely free to download and free to use. Private messages, group chats, voice messages, and Dyno reactions are all included at no cost. No subscription fees. No ads. No data selling. No behavioral tracking. Just honest, straightforward messaging.

SIMPLE TO GET STARTED
All you need is your phone number. Sign up in minutes, set your unique Dyno username, and start messaging right away. Once your account is created you can sign in with either your phone number or your unique username. Share your username to connect without ever sharing your phone number.

YOU ARE IN CONTROL
On Dyno nobody can send you a message unless you have accepted their friend request first. Not from your phone number. Not from your username. Nobody gets through until you say so. This means zero unsolicited messages. Zero spam from strangers. Zero unwanted contact from people you do not know. Every single person in your Dyno inbox
is someone you chose to let in.

BORN FROM A METEORITE
Every Dyno has an origin story. Ours started with a meteorite, an egg, and a little dinosaur who just wanted to connect with the herd. That spirit is in every message you send, because great conversations, like great dinosaurs, are worth protecting.

Join the herd!
