When AirDrop can't reach — a Windows PC, an Android phone, or no internet at all — Droproom can. No cloud. Files move straight between devices — everything stays on your own phone. No server, no account, no waiting for uploads. Phone ↔ computer, effortlessly. Open a browser on the computer, type the address on screen, tap "Let in" on your phone — connected. No cable, no login, no emailing files to yourself. Cross-platform, the same way. iPhone, Android, Windows, Mac — anything with a supported browser joins. Nothing to install. People nearby scan the QR code and the files appear in their browser. Both sides can add and take. What you add and what they add stays between your devices. Transfers stay on your local network and are unencrypted — share with people you trust. End the share and it's gone from the network. Free to download and use. A one-time purchase unlocks unlimited sharing — no subscription, no ads.
