Is the transfer encrypted?

Yes. Each transfer is end-to-end encrypted with the age protocol (X25519 and ChaCha20-Poly1305), the same crypto core used by AgePony.

Do I need an account?

No. There is no sign-up and no login. You pair two phones by scanning a QR code and that is all.

Q: How do two phones connect without a server?

On the same Wi-Fi, RelayPony finds nearby devices using local network discovery (mDNS / Android NSD) and streams the file directly between them. When there is no shared network, it falls back to a direct device-to-device link. In every case the file goes phone to phone, never through a server.

Q: Do both phones need to be on the same Wi-Fi?

It is the easiest path, but not required. If there is no common network, RelayPony links the two phones directly so you can still send.

Q: Where do received files go?

They arrive in the app's Inbox, and can auto-save to your Downloads folder if you enable that.

Quickstart

01 · Get the app

RelayPony is in closed testing on Google Play. Join the list on the home page to get a tester invite, or to be notified the day it launches publicly.

02 · Pair the two phones

Open RelayPony on both phones. One phone shows a QR code; the other scans it. That pairs them on a trust-on-first-use basis, so they recognize each other for future transfers.

03 · Send a file

Pick the files in RelayPony, or share into RelayPony from another app's share sheet, then choose the paired device. The file streams across, encrypted with age, with live progress while it moves.

04 · Receive a file

An incoming transfer shows up on the other phone with progress, and you can stop receiving at any time. When it completes, the file is in the Inbox, and saves to Downloads if you have that turned on.

Frequently asked

How do two phones connect without a server?

On the same Wi-Fi, RelayPony discovers nearby devices with local network discovery (mDNS / Android NSD) and streams directly between them. When there is no shared network, it falls back to a direct device-to-device link. The file always goes phone to phone, never through a server.

Is the transfer really encrypted end to end?

Yes. Each transfer is encrypted with the age protocol, X25519 key agreement and ChaCha20-Poly1305, the same verified core that AgePony uses. The file is encrypted on the sending phone and decrypted on the receiving phone.

Do both phones need to be on the same Wi-Fi?

It is the simplest path and the fastest, but not required. With no common network, RelayPony connects the two phones directly so you can still send.

Where do received files go?

Into the app's Inbox first. If you enable auto-save, they also land in your Downloads folder.

Does it work without an account?

There is no account at all. Nothing to sign up for, nothing to log into. Pairing is a QR scan and identities are held on each device.

Troubleshooting

The other phone doesn't show up

Make sure both phones are on the same Wi-Fi and have RelayPony open. Some networks (guest Wi-Fi, certain corporate or public networks) block the local discovery that lets devices see each other. If that's the case, use the direct device-to-device option instead of relying on the shared network.

A transfer stalls or drops

RelayPony reports real progress and will retry a dropped connection with backoff. If it can't recover, cancel and start the transfer again. Keeping both phones awake and near each other during a large transfer helps.

I can't find a received file

Check the Inbox inside RelayPony first. If you expected it in Downloads, confirm auto-save to Downloads is enabled in settings, then resend.

Pairing didn't take

Re-open RelayPony on both phones and scan the QR code again. Make sure you're scanning the correct phone's code; trust-on-first-use means the device you scan is the device you'll send to.
