QRefine: QR Scanner & Maker

QRefine is a QR code scanner, generator and manager in one app. Scan with the camera, create a code from text or binary data, and keep everything you scan in a searchable list.

Unlike a basic QR scanner, QRefine reads the detailed parameters of a code and lets you generate with them, so a scanned code can be reproduced with the same pattern instead of being re-encoded into a different one.

If another app shows garbled text when scanning a code, that code is probably binary. QRefine decodes it, shows the content as hex and text side by side, and explains what is inside.

■ Scanner
- Scan QR codes with the camera
- Import an image and detect the code inside it
- Read a code from a screenshot or a photo in your gallery
- Read binary payloads that a normal QR code reader cannot display
- View the scanned content as text or as hex

■ Generator
- Create a QR code from text you type in
- Create one from binary data entered as hex
- Generate with a specific error correction level, mask pattern and QR version
- Turn a blurry or low-resolution code into a clean, scannable image
- Save the result as a PNG
- Export binary data as a file and share it with other apps

■ Manager
Most QR code apps give you a scan history. QRefine gives you a library.
- Name everything you save
- Add a memo to each entry
- Search by name or memo
- Sort and reorder your list
- Delete what you no longer need
- Back up the whole list to a file
- Restore it on a new device

■ About binary QR codes
QRefine is built around binary support. Game codes and enterprise codes often carry raw binary rather than text, and a normal QR code scanner either fails on them or mangles the data. QRefine reads the binary exactly, shows it as hex, lets you edit it, and generates it back out.

■ Who uses QRefine
- Developers and QA engineers testing payloads, error correction levels and mask patterns
- Business and enterprise users handling binary data in QR codes
- Players who receive game codes as images and need a scannable version
- Anyone who collects Wi-Fi, ticket, payment or contact codes and wants them organized

■ Other features
- Dark mode
- A simple interface with no clutter
- Scan, create, organize and reuse, all in one place

If you need a QR code reader that is accurate, a generator that is precise, and somewhere to organize what you keep, QRefine is the QR code app for you.
