Barcode Generator vs Brian's Power Calculator

Barcode Generator makes barcode labels, prints them, and reads barcodes with your camera. Everything stays on your device. CREATE • 20 barcode types: Code 128, Code 39, Code 93, Code 11, EAN-13, EAN-8, UPC-A, UPC-E, ISBN, Interleaved 2 of 5, Standard 2 of 5, Codabar, MSI Plessey, Pharmacode, POSTNET, Australia Post 4-State, QR Code, Data Matrix, PDF417 and Aztec. • The preview updates as you type. Check digits are added for you, and a value that cannot be encoded says why. • Serial numbers: step the number up or down (SN-0099 to SN-0100), or go to the next number automatically after each print. • Give a label a name, such as "Front door" or "Shelf A3", so it is easy to find later. PRINT • AirPrint to any printer, including roll-fed label printers, which use only as much paper as the sticker needs. • Print sheets: choose saved barcodes, set how many copies of each, pick 1 to 4 columns on A4 or US Letter, add dashed cutting guides, and preview every page before printing. • Label colour with adjustable opacity. A contrast check warns you if a colour would make bars hard to scan. SCAN • Scan with the camera, with a torch for dim places, or read a barcode from a photo. • Reads QR Code, Data Matrix, PDF417, Aztec, EAN, UPC, Code 128, Code 39, Code 93, Interleaved 2 of 5 and Codabar. • Open links, copy the value, or turn any scan into a printable label. ORGANISE • Every saved and scanned code in one searchable list. • Export the whole list, or just the codes you select, to an Excel workbook with a picture of each barcode, its name, value and type. • Share any barcode as an image. MAKE IT YOURS • Three themes, Indigo, Ocean and Graphite, each in light and dark. • Works on iPhone and iPad. PRIVATE BY DESIGN No account, no ads, no tracking. The app collects no data and sends nothing anywhere. Your barcodes are stored only on your device.
