About this app

InvoStock is an inventory counting app for warehouses, retail stores, and anyone who counts physical stock.

Import a task list as CSV, walk the floor scanning barcodes with your phone camera or a Bluetooth scanner, and export clean results when done. No paper lists, no manual data entry.

How it works:
1. Create a task and import your item list from a CSV file
2. Scan barcodes on the warehouse floor or in the shop
3. Review progress, mark items not found, handle unknowns
4. Export results as CSV and share with your team

Key features:
- Barcode scanning: EAN-13, EAN-8, UPC, Code 128, Code 39, QR, DataMatrix and more
- Cumulative barcode database that learns product names across tasks
- Pack size tracking: scan one barcode for a box of 12 and get the right total
- Blind counting mode for standard audit methodology
- Append-only count journal with full correction history
- Unidentified items logged with optional photos
- Multiple tasks at once without losing progress
- Flexible CSV import with automatic column detection

Fully offline:
All data stays on your device. No server, no cloud, no account, no subscription. Your counting data never leaves your phone unless you export it yourself. Built on SQLite for fast, reliable local storage.

Who uses InvoStock:
- Warehouse teams doing periodic stock counts
- Retail stores counting inventory at end of day or month
- Logistics crews verifying shipments against manifests
- Small businesses managing stock without an ERP

Free, with no ads and no in-app purchases.
