Whoosp is a free web app for sending files and messages between phones and computers. Create a temporary room, share its 4-character code or QR code, and anyone who joins can exchange photos, PDFs and documents up to 15 MB. There is no account and no app to install, and it works across different networks, not just the same Wi-Fi. Everything is deleted when the last person leaves. The app itself needs JavaScript.
