XYNN QR makes QR codes on your device and keeps them there.

No account. No sign-up. No analytics. No advertising. The app requests no Android permissions at all, and it does not use the camera, because it generates codes rather than scanning them.

WHAT YOU CAN ENCODE

• URL — any web link
• Text — plain notes
• Wi-Fi — network name, password and security type, so guests can join by pointing a camera
• vCard — a full contact card
• Email — address, subject and message
• SMS or phone call
• Geo — a map coordinate
• Event — a calendar entry with start and end times
• Crypto — a wallet address, with an optional amount

MAKE IT YOURS

Choose square, rounded or circular modules. Pick from a set of code and background colours, or dial in your own with a colour wheel. Add a gradient, drop your mark into the centre, or write a caption to sit in a bar under the code — long captions shrink to fit. Four one-tap presets get you a good-looking code immediately.

CODES THAT ACTUALLY SCAN

Styling a QR code can quietly break it. XYNN QR checks the contrast between your code and its background as you edit, shows you the ratio, and blocks the export if it drops too low to read. The quiet zone around the code cannot be reduced past the point where scanners stop finding it.

EXPORT

Save as PNG, SVG or PDF, at sizes from 256 to 2048 pixels, with an adjustable quiet zone and error correction level. Share straight to another app, or save to your device and choose where it goes.

YOUR LIBRARY

Every code you export is kept in a local history so you can find it again or reuse its settings. Star a design to keep it in a separate saved list; tap the star again to remove it. All of it lives in your device's own storage, and uninstalling the app removes it.

ALSO ON THE WEB

The same generator runs in a browser at qr.xynn.io, with the same on-device-only behaviour.
