Current latest: Check Digit Calculator v1.1
Archived editorial snapshot
Check Digit Calculator v1.1 archive notes
Check Digit Calculator v1.1 is a compact barcode utility for completing a product identifier when its final check digit is missing. Users can choose a GTIN length, enter the known digits, and receive the calculated result, which is useful during stocktake or manual label entry. The release also includes a beta barcode and QR scanner, a camera-flash torch for darker labels, in-app help, and a Settings page close to the main menu. It targets Android API level 4 and uses legacy target API level 14, so newer Android releases may require a compatibility workaround before installation. The downloadable file is a standard APK with camera, microphone, media, nearby-device, notification, Bluetooth, network, and related declarations.
Complete missing GTIN check digits
Use the calculator to finish a GTIN when a product label contains the identifying digits but lacks its final check digit. The returned number keeps the manual-entry task focused, which is useful for warehouse stocktakes, retail checks, and quick verification away from a larger inventory system.
Read labels with the scanner and torch
The beta scanner can read barcode and QR values and return their type, helping users avoid retyping a visible label. A built-in torch can illuminate darker boxes or shelves, so camera-based work remains practical in dim storage areas.
Use built-in guidance for barcode tasks
Help pages explain the main calculation path, GTIN formats, and the meaning of the result. In v1.1, a Settings page joins the calculator, scanner, torch, and help routes, giving repeat users a compact place to adjust the app's basic setup.

Version-specific notes for this archived release.
Which updates are recorded for the v1.1 release?▾
The v1.1 release notes list updated help files and the addition of a Settings page. The calculator and beta barcode/QR scanner remain the release's central tools, while the notes do not claim a new calculation method or make every future code family available. For this reason, the archive should be read as a GTIN-focused utility release with an expanded help and settings experience.
