Send and receive files using the Magic Wormhole protocol
About this app
This is an Android client for the Magic Wormhole protocol. You can use it to exchange files between your phone and another Magic Wormhole client, including the original command-line client.
How to send files
* From the main screen, tap the "send" button. Then use the "choose file" button to pick the file that you want to send. * Alternatively, open the file that you want to send and tap the share icon: Wormhole should be listed among the apps you can use to share the file. * Either way, the app will have generated a code, a random number followed by two random words. The person to whom you want to send the file will have to enter this code in their Magic Wormhole client. The code is also copied to the clipboard for convenience. * Tap the "send" button. When the user at the other end of the wormhole enters the code and confirms, the file will start transferring. * The "send" button will change to "done" when the transfer is complete.
How to receive files
* From the main screen, tap the "receive" button. * Enter the code that the sender has provided you with and tap the "connect" button. * You will see the incoming file's name and size. If all looks good, tap the "receive" button to start the file transfer. * When the file is downloaded from the wormhole, the "receive" button will change to an "open dir" button.
The app is still in beta and there is still a lot to be desired. However, the basic functionality of sending and receiving files seems to be there. I find it useful, so someone else might as well.
The code is open sourced under GPLv3. Pull requests are welcome.

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be com.pavelsof.wormhole is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
No earlier build is on record for Wormhole, so there is nothing to roll back to yet. When a second version is published, this section will explain how to move between them safely.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Wormhole, and a listing is removed when the evidence for it stops holding up.
Get Wormhole
Every source we list for com.pavelsof.wormhole is legality-reviewed. Pirated or cracked builds are never offered.

Permissions Required
What each permission lets Wormhole do. A highlighted one is worth a second look — not necessarily wrong, just worth asking whether this app needs it.
Previous Versions
No earlier build is on record — this is the first release we have listed.
The signing certificate fingerprint for this release is on record, so a build that does not match it did not come from this publisher.
