Whether you are a teenager looking to gossip with your friends or business professionals looking for a way to connect with partners and clients. Chadder is the easiest private IM app on the market. With multiple devices and the ability to send photos, you will never be without something to say. For the first time, you can control your information. Our encryption system locks your message before it's sent, through our servers, and then unlocks it only once it reaches its destination.

We use ECDH with the SecP256k1 curve (the same form of encryption that Bitcoin uses), combined with AES 256. We also use ECDSA to sign the message. Our user key thumbprints use SHA-1.

Chadder is always updating, with new features and technology come participate in the creation process. The app will evolve over time to have a more diverse set of features per your requests. Follow us on Twitter: @chadderforall or Facebook: Chadder to participate in the future of communication.

Ratings and Reviews

Neat, but not good.


Needs polish. Vague and confusing messages, undocumented features with no visual indication that they did anything (scanning fingerprints, for instance), and slow servers hamper the usefulness. I was not able to pair devices or delete a duplicate device that showed up. I can only guess that it works for messaging.

Can't even make an account


Please fix your servers I really want to use this app.

Great Job!!


Excellent work!! I feel much more confident sending texts and photos knowing that my messages are protected from anyone other than the receiver.
