I got tired of emailing photos to myself.

My iPhone and my Windows laptop sit about forty centimetres apart, and the fastest way to move a photo between them was still my own inbox. AirDrop doesn't reach Windows, and Apple doesn't let third-party apps send files to Windows over Bluetooth, so no app can copy it directly.

So I built UFTI (Unified File Transfer Interface). Open it on the PC, scan the QR code with your phone camera, and send. The phone opens a web page in its own browser, so there is nothing to install on it.

What it does:

• Sends files, photos, videos and text in both directions

• Keeps everything between your own devices. No cloud server, no account, no tracking

• Handles multi-gigabyte videos

• Works with no Wi-Fi by creating its own hotspot network

• Works with iPhone, Android and any phone browser
