WallyMatesDownload WallyMates
No need to install anything — the web version works for a one-off conversation, no setup required.
The Android app is distributed directly (not via Google Play) — your system may warn about an unknown source during install, that's expected.
WallyMates is available on three platforms — pick whatever's convenient right now, not forever: the account and conversations are the same everywhere.
WallyMates for Android
A native app: private chats with end-to-end encryption (Static X3DH + AES-256-GCM), groups and channels with an admin panel, voice and video calls, sending photos/video/files with automatic media compression, and push notifications via Firebase. Secret chats with a self-destruct timer are only available in the app.
WallyMates for Windows
A desktop client using the same end-to-end encryption protocol as Android (wire-compatible — conversations sync without losing the E2EE guarantee). The same groups, channels, and calls, plus desktop conveniences: a floating call mini-window, output device switching, and screen sharing without third-party software.
WallyMates in the browser
No installation needed — open web.worldmates.club in any modern desktop browser and sign in with the same account. Good for a one-off conversation from someone else's computer. Private chat history syncs into the browser through a separate mechanism (see the security section below); the web version itself is excluded from search engine indexing.
One account, every device
Sign in to the same account on Android, Windows, and in the browser at the same time — messages, groups, and channels are available wherever you're signed in. Start a conversation on your phone and continue on your computer: history and unread messages just show up, no manual export or transfer needed.
