Chats, calls & money, on one Cubeline.
Private messaging, voice and video calls, status, channels and a Naira wallet in one app. Everyone you reach is a Cubeline, and nobody needs your phone number.
Five tabs. Everything you need.
Chat, Status, Calls and Wallet sit side by side at the bottom of the app, with Settings one tap away. Pick a tab to see it.
Military-grade privacy. Now in your pocket.
Cube App is built so that only the people in a conversation can read it, and nobody in between learns who is talking.
Messages, files, statuses and calls are locked on your device and opened only on theirs.
Messages and calls hop through CubeNet, our onion network, so no server learns who is talking to whom.
Voice and video calls go through relays, so the other person never learns your IP address.
Sign up with a username and a password. Your Cubeline is the only address people need.
Private, and full of life.
Encryption keeps the words safe. Little touches make them land.
Words like love, miss and congrats light up in the bubble, so the feeling lands.
Say happy birthday and the chat celebrates with them.
Answer with 👍 ❤️ 😂 😮 😢 🙏 without typing a word.
Calls end with a warm line instead of a cold "call ended".
Pick a background for each chat, or keep the Cube doodle.
Send photos, files and messages on to anyone in a couple of taps.
Invite people you chat with, or share a group link like cubechat.org/join/yourgroup. An admin approves each request.
Two grey ticks when your message reaches someone in the group, blue when they read it.
Send big videos and documents, and watch each download fill as it arrives.

Clear voice and video over the internet, encrypted end to end. No airtime, no SIM.
