CartCheck

🛒 CartCheck — Stop racking your brains trying to keep track of deals like "Get 5,000 won off on purchases over 50,000 won" every time you go to the supermarket.

CartCheck is a household budget app that allows you to pre-register the minimum discount threshold and applicable discount amounts for each store. It displays in real-time how much of your total purchase amount remains to reach your goal while you shop.

■ Key Features

✅ Target Amount & Discount Amount by Store

E-Mart: 5,000 won off on 50,000 won, Costco: 10,000 won off on 100,000 won — Pre-register different discount conditions for each store. These conditions are automatically applied when you select a store.

📷 Price Tag OCR (On-Device)

Simply point your camera at a price tag, and Google ML Kit will automatically recognize the product name and price (regular price, discounted price, or sale price). Photos are not saved.

🎯 Real-time Progress Tracking

Check your current total purchase amount, the amount remaining to your goal, and the discount amount you will receive upon reaching it all at a glance on the home screen.
