Why another messaging app?

sndr is not just another messaging app. It is a secure unified communications app that gives you free messaging and unlimited size file sharing, along with some other amazingly useful features.

Why another cloud storage app?

sndr is not a cloud storage app. We empower you to share and stash unlimited sized files, but that’s just one of the gazillion features we have to make your communication easier, limitless and fully protected. When you use sndr Block with the sndr app, you have a hybrid personal communication system. And we never store your decrypted information in the cloud. Ever. All of this is possible because only you and your recipients can decrypt your messages and files.

How do you differ from other communication platforms?
