aTox is a free open-source messaging app for the Tox protocol. Why aTox? * Open-source: free to share, inspect, and change as you like. * Reasonable: sane defaults, no guesses about what you care about, doesn't ignore what you want. * End-to-end encrypted: the only people who can see your conversations are the people you're talking to. * Distributed: no central servers that can be taken down or compelled to turn over data. * Lightweight: no telemetry, ads, or other forms of monitoring.
