Parawz vs Duet

Move the divider bar between them to adjust the height of each pane. Watch videos while browsing social media. Read comics while doing research. Split the screen however you like and make it fit your style.

Duet sends what matters from one phone to another — and gets out of your way. Pick a file, a contact, a Wi-Fi password, a 2FA setup code, or any text. The sender shows a QR code; the receiver scans it. For larger files, the two phones connect directly over your local network. Everything is end-to-end encrypted, and nothing ever touches a server. No account. No sign-up. No ads. No tracking. No cloud. WHY DUET • Reliable by design — built to finish the transfer, every time. • Truly private — your data goes phone-to-phone, never through us. We can't see it because it never reaches us. • Zero clutter — no ads, no upsells, no “create an account” wall. WHAT YOU CAN SEND • Files of any kind — documents, photos, videos, archives. Streamed directly, so size isn't a problem. • Wi-Fi credentials — share your network without reading the password aloud. • Contacts — send a contact card that drops straight into the other phone. • 2FA / authenticator setup codes — move your TOTP seeds to a new phone. • Plain text and links. HOW IT WORKS • Small items travel in a single QR code — scan and done, no network needed. • Larger items use animated QR or a direct local-network link between the two phones. Your data stays on your local network; it never goes to the cloud. • Every transfer is encrypted end-to-end. For the local-network mode, both phones show a quick visual match-check first, so you know there's no one in the middle. PRIVACY YOU CAN VERIFY • Data Not Collected. No analytics SDKs, no ad SDKs, no trackers. • No internet connection is used to move your data. • Transfer contents are never written to permanent storage. Duet is free, and it stays free. No subscriptions, no “pro” paywall on the core transfer.
