GS1Barcode is a local-first professional tool for GS1 / UDI barcode scanning, GS1 Application Identifier parsing, FNC1 and Hex inspection, batch review, history, and CSV/JSON export.
When contacting support, please include the app version, iOS version, device model, barcode type if known, and a short description of the issue. Do not send sensitive barcode data unless you have permission to share it.
Core purpose: GS1Barcode helps professional users scan, parse, inspect, and verify GS1 / UDI barcode data locally on the device.
Camera: used for local real-time barcode scanning. The app does not upload camera frames or scan data.
Photos: barcode image import uses Apple PHPicker and only processes the image you choose. The app does not request full photo library access.
Clipboard and sharing: used only when you choose to copy, export, or share barcode data through iOS system features.
No. GS1Barcode is an independent local scanning, parsing, and field verification tool. It is not an official GS1 app and does not provide GS1 certification.
No. The app can help review common UDI data elements and inspect barcode payloads, but it does not provide legal, regulatory, or medical compliance certification.
No. In the current release, scanning, parsing, history, and export are local-first. Data leaves the app only when you explicitly copy, export, save, or share it.
Camera access is used to scan barcodes in real time. If you do not grant camera access, camera scanning will not work, but other local functions may still be available.
The app focuses on GS1 / UDI barcode payloads and GS1 Application Identifier field parsing. Support depends on the barcode content, symbol quality, and whether the payload follows expected GS1 semantics.
Email support with the app version, iOS version, barcode type, a description of the expected field result, and a sanitized sample if you are allowed to share it.
GS1Barcode is designed for local scanning, parsing, debugging, and field verification. It does not replace professional quality procedures, regulatory review, or official GS1 / UDI certification programs.
