On your phone?
Scan this with the camera to download the Android app.
Windows
Windows 10 or 11. Run the installer. If Windows shows "Windows protected your PC", the installer is new and not code-signed yet: click More info, then Run anyway. You can compare the SHA-256 above with your file first.
The installer can add "Send with GleamShare" to the right-click menu and start GleamShare quietly with Windows so your PC is always ready to receive.
Android
Android 10 or newer. Open the downloaded file. Android asks you to allow installing from your browser once. Put your phone on the same Wi-Fi as the other device and open GleamShare.
Mac, Linux, iPhone and iPad
Use the web app in your browser. It works on any device, and link and email sharing reaches anyone.
Not seeing your device?
Both devices need the same Wi-Fi, "AP isolation" or "client isolation" must be off on the router, and the Windows Firewall must allow GleamShare (the installer adds a rule). You can also add a device by typing its IP address from Settings.
