AlterSend
Send files directly between devices over the internet with no limits
...Open AlterSend on the sending device and pick your files.
2. Share the short join code (or QR) with the receiving device.
3. The other device enters the code, and the transfer starts.
4. Files move directly, peer-to-peer, encrypted end-to-end.
It works on the same Wi-Fi network and across the internet — same code, same speed, no setup. If both devices are on the same network, transfers happen at LAN speed.
