## Description

Unit Price Scanner calculates the cost per 100g or per kg from supermarket price tags — just point your camera.

Designed for shopping at Japanese supermarkets. The app reads Japanese price labels with OCR, then instantly shows the unit price so you can compare products in seconds.

[Features]
• Automatic unit price calculation from price tags (camera or photo library)
• Switch between cost per kg and cost per 100g at any time
• Correct OCR misreads on screen — manual entry always available
• Scan history with photos (up to 30 entries, swipe to delete)
• Weight estimator for fish and produce when weight is not on the tag
• Reference prices from Japanese market data for context
• All data stays on your device — no sign-in, no network required

[Note]
This app is designed specifically for Japanese price tags. It uses Japanese OCR to recognize labels written in Japanese. Price tags in other languages are not supported.
