The messenger from Nkonso
PrivateConversations,Carried Far.
Chats, voice notes and calls that only you and the people you choose can hear. Atumpan is named after the talking drums that carried word from village to village, and it carries yours just as far, even on a weak signal.


Message privately
Only You and the People You Choose Can Read It.
Your personal chats and calls are end-to-end encrypted with MLS, the open standard behind the next generation of secure messaging. Not even Atumpan can read them. Business, team and young people's chats are protected differently, and the app always tells you which is which.
- An Honest Label on Every ChatThe amber lock means end-to-end encrypted. The teal shield means encrypted in transit and at rest, and readable by a business or a team.
- Strangers Wait OutsideMessages from people you don't know land in requests, with photos blurred and links switched off until you accept.
The drum answers
Receipts You Can Read in a Heartbeat.
Atumpan's receipts are a pair of drum heads, not ticks. One when it leaves you, two when it reaches them, both lit amber when they read it. Hollow or solid carries the meaning, so nobody needs to tell colours apart.

Calls That Hold On When the Network Doesn't.
Call one person or the whole family, by voice or video. When the signal dips, Atumpan drops the picture before it drops the call, keeps the voice clear and brings the video back when it can. One-to-one calls between adults are end-to-end encrypted.
Groups
Groups With Owners, Admins and a Front Door.
Family, church, class, the book club, the old school mates. Nobody gets dropped into a group they didn't choose: new members knock, and an admin lets them in. Quiet hours and @mentions keep a busy group from shouting at night.
Everything groups can do
Say it your way
Voice Notes, Photos, Replies and Reactions, All Light on Data.
Hold to Talk, Tap to Send.
One amber button. Hold it for a voice note, slide up to lock it and keep talking hands-free, listen back before it goes, and play the ones you receive at 1.5脳 or 2脳.

Photos and Videos in Full Colour.
Send them sharp, or in data saver. Previews stay blurred until you tap, and you choose what downloads on mobile data.
Reply, React, Edit.
Swipe to reply to one message, react with any emoji, edit a typo or delete for everyone.
Kind to Slow Networks.
Messages wait offline and send in order when the signal returns. Small downloads, a data saver and no surprise bills.
Phone, Tablet and Web.
Link a tablet or a computer and your chats follow you, encrypted on every device.
Usernames, not numbers
One @username. Your Number Stays Yours.
Give someone your @username, your QR code or your atumpan.com link instead of your phone number. Your number is hidden by default; being found by it is a switch you control. The same username works on Amee, so you only claim it once.
How usernames keep you privateWallpapers
Fourteen Wallpapers, Drawn From Home.
Adinkra, kente, gold weights, the Volta and Accra at dusk: original art, named in Twi, Fante, Ewe and Ga. Pick one for every chat or a different one for each.
Fourteen originals drawn from Ghana, plus None. Every one comes in light, River night and Graphite, the true-black dark for OLED phones.
Business and teams
Talk to a Shop the Way You Talk to a Friend.
Ask the tailor if your kaba is ready, confirm a booking, get the receipt in the chat. Businesses on Atumpan show their Agoo Reviews score right in the chat, so you know who you're dealing with. And organisations on Agoo Workspace move their staff off scattered groups into team chat they own.

Reviews You Can Trust, in the Chat
A business's Agoo Reviews score sits in its chat header and opens its full page, so a good reputation travels with every conversation.
