Features

Everything You Need to Keep In Touch.

Chats, voice notes and calls that stay private, groups that stay calm, and an app that's gentle on your data. Here's all of it.

Chats

Every Kind of Chat, Readable at a Glance.

People, groups, businesses and your team in one list, each marked by how it's protected. Pin the chats that matter, archive the rest, and mute anything for an hour, a day or always.

  • Disappearing MessagesSet a chat to clear itself after a day, a week or ninety days.
  • Search That Stays on Your PhoneEncrypted chats are searched on your device, never on our servers.

Receipts

One Drum When It Leaves You. Both Lit When It's Read.

SendingOne dashed drum head: still on your phone. It waits offline and goes when the signal returns.
SentOne drum: it left you and reached Atumpan.
DeliveredBoth drums: it's on their phone. In a group, on everyone's.
ReadBoth lit amber: the drum answered. Hidden for both of you if either turns read receipts off.

Voice notes

Hold to Talk, Tap to Send.

Some things are better said than typed. Hold the amber button and talk; slide up to lock it and keep going hands-free; listen back before it goes.

  • Play FasterListen at 1.5脳 or 2脳 and pick up where you left off.
  • Small FilesVoice notes are compressed for slow networks without losing the voice.
  • Waits for the SignalRecorded offline, sent the moment you're back.

Voice and video calls

Calls That Hold On When the Network Doesn't.

Call one person or the whole family. When the signal dips, the picture goes before the call does, the voice stays clear, and the video comes back when it can.

  • End-to-End EncryptedOne-to-one calls between adults, like your personal chats.
  • Your Phone's Own Call ScreenAnswer from the lock screen with CallKit on iPhone and the system call screen on Android.
  • Group CallsBring the family into one call; the person speaking is ringed in amber.

Groups

Groups With Owners, Admins and a Front Door.

Nobody lands in a group they didn't choose. People knock with a join request, and the group's admins let them in, or share an invite link that can be switched off any time.

  • Owners and AdminsDecide who can add people, change the name or post, and pass ownership on.
  • Quiet Hours and @mentionsBusy groups stay silent at night unless someone mentions you.
  • Polls and Pinned MessagesSettle the date and keep the address at the top.

Photos, videos and files

Share the Moment, Sharp or Saver.

Photos and videos in full colour, documents, contacts and your location. Every file is checked for harm before it reaches anyone, in the chats where we can see files.

  • You Choose What DownloadsPer type, on mobile data and on Wi-Fi.
  • Blurred Until You TapPreviews stay soft, so a chat never spends your data by surprise.
  • Share a Live LocationFor fifteen minutes, an hour or eight, and stop any time.

Phone, tablet and web

Your Chats on Every Screen You Use.

Link a tablet or a computer by scanning a code with your phone. Each device holds its own keys, so your encrypted chats stay encrypted everywhere, and you can unlink one from any other.

  • Encrypted BackupLocked with a recovery key only you hold. We can't open it.
  • A New Phone, the Same ChatsMove with your recovery key, or straight from the old phone.

Usernames

Share an @username, Not Your Number.

Your phone number is hidden by default. People start a chat with your @username, your QR code or your atumpan.com link, and you choose whether anyone can find you by number at all.

Wallpapers and themes

Light, River Night and Graphite. Fourteen Wallpapers.

Three themes, each designed rather than inverted: light, River night (the teal-tinted dark) and Graphite, true black that saves battery on OLED phones. And fourteen original wallpapers drawn from Ghana.

茊p蓻Harmattan 路 The dry season's soft haze. The default.

Fourteen originals drawn from Ghana, plus None. Every one comes in light, River night and Graphite, the true-black dark for OLED phones.

Built for real networks

A Full Chat on a Slow Network and a Small Phone.

Works Offline

Messages queue on your phone with the sending receipt and go in order when the signal returns.

Data Saver

Lower-quality media on mobile data, smaller calls, and nothing downloads that you didn't ask for.

Light on Older Phones

A small app that starts fast and stays smooth on entry-level Android phones.

Your Languages

English first, with Twi, Ewe and Ga greetings throughout, and every letter of them drawn properly.

Calm Notifications

No streaks, no nudges, no badges designed to pull you back. Quiet hours for any chat.

Private by Default

Number hidden, read receipts and last seen yours to switch off, and strangers in requests.
