Barcode Plotter — POS Item Plotter

Barcode Plotter is a fast, offline barcode generator and on-screen "plotter" built for retail, point-of-sale (POS) testing, inventory checks, demos, and training. Load a list of codes from a simple text file and the app renders crisp, scannable barcodes right on your screen — one after another on a timer, or on a single tap — so you can test scanners, POS terminals, and workflows without printing a single label.

Whether you're a developer validating a checkout system, a store owner testing a new scanner, or a trainer running a demo, Barcode Plotter turns your phone or tablet into an instant, reusable barcode source.

✨ Key features

• 13+ barcode formats — Generate EAN-13, EAN-8, UPC-A, UPC-E, Code 128, Code 39, Code 93, ITF, Codabar, QR Code, Data Matrix, Aztec, and PDF417 from the same data file. Switch formats any time from Settings.

• Plot from your own data file — Pick any text file of codes (one value per line) using the system file picker. A built-in sample data set is included so you can start instantly.

• Auto-cycle or manual — Press Start to automatically cycle through your codes at a configurable interval (default 5 seconds), or tap the barcode to plot the next one on demand. Pause and resume anytime.

• Sequential or Random mode — Plot codes top-to-bottom in a continuous loop, or pick them at random — perfect for varied test runs.

• Crisp, scannable rendering — Barcodes are drawn at full resolution so real scanners read them reliably straight off the screen, with proper quiet zones.

• Export to PDF — Generate a clean, paginated A4 PDF of all your codes with one tap. Each page includes a titled header with date, a 3-column table (serial number, value, barcode), neat separators, and page numbering — saved straight to your Downloads folder.

• Modern, distraction-free UI — A sleek dark dashboard puts the barcode front and center, with live value, barcode type, status, and a running counter.

• Helpful feedback — Optional sound cues for refresh, clicks, and errors.

• Always up to date — Built-in Google Play in-app updates keep you on the latest version.
