Everything to stay in touch
Chats, calls and meetings in one place
From a quick voice note to a full group meeting — encrypted messaging, adaptive calling and the tools that keep teams and families in sync, all in a single app.
End-to-end encrypted
1:1 and group chats are private by default, secured with Signal-protocol-style encryption. Only the people in the conversation can read it — not even Olbongo.
Voice & video calls
Crystal-clear one-to-one and group calls, plus scheduled meetings, powered by a LiveKit SFU that adapts to your bandwidth so calls hold up on weak networks.
Turn a call into a room
Add online participants mid-call to grow a 1:1 into a group, with in-call chat that writes to the same conversation — nothing gets lost when the call ends.
Shareable call links
Invite anyone with a link. A knock-and-admit lobby keeps you in control of who joins, so the right people get in and no one else does.
Presence & receipts
See who's online and last-seen, watch typing indicators in real time, and know exactly when a message is delivered and read.
Voice messages & media
Send a quick voice note, share photos, videos and files, react with emoji, and pin the messages that matter so they never scroll away.
Polls, reactions & pins
Run a quick poll, react to any message, and pin decisions to the top of the chat — the small tools that keep group conversations moving.
Real-time & reliable
Messages reorder live as they arrive and queue offline, sending automatically the moment you reconnect. Built to survive spotty connections.
One identity, everywhere
The same account you chat and call with is the one you use for mail, your Woza feed and your storefront — one login across web and mobile.
How it works
Start a conversation in three steps
Message anyone
Start a private 1:1 or group chat from your organization contacts. Everything is end-to-end encrypted by default.
Call or meet
Tap to start a voice or video call, or spin up a meeting — add people mid-call or share a link with a knock-and-admit lobby.
Stay in sync
Presence, receipts and live reordering keep everyone aligned, and messages queue and send the moment you're back online.
Private by design
Only you and the people in the chat
Olbongo secures conversations with Signal-protocol-style encryption — an X3DH key exchange and a Double Ratchet that gives every message its own key. In between, it's unreadable ciphertext, even to us.
- X3DHA secure key agreement establishes a private session between devices.
- RatchetEvery message gets a fresh key, so past and future messages stay protected.
- Default1:1 and group chats are encrypted end to end automatically — nothing to switch on.

Frequently asked questions
Are my messages really private?+
Yes. Both 1:1 and group chats are end-to-end encrypted with Signal-protocol-style cryptography and are private by default, so only the people in the conversation can read the contents — not Olbongo.
How good are calls on a slow connection?+
Calls run on a LiveKit SFU that's bandwidth-aware and tuned for African networks, so it adapts quality to hold the call together on weak or mobile connections. Messaging is designed to work down to 2G.
Can I add people to a call after it starts?+
Yes. You can add online participants mid-call to turn a 1:1 into a group, or share a call link. Anyone joining by link passes through a knock-and-admit lobby so you decide who gets in.
What happens if I lose connection while chatting?+
Nothing is lost. Messages queue locally and send automatically the moment you reconnect, and the timeline reorders itself correctly as messages arrive, so conversations stay consistent across your devices.
Do I need a separate app for calls and meetings?+
No. Chat, voice and video calls, group calls and meetings all live in the same Olbongo app on web and mobile, using one identity you already have for mail, your feed and your storefront.
