About this app

When you see a discount sticker at the supermarket, there is a question that often crosses your mind:

"How much was this before?"

MartLog is a small price notebook for that very moment. If you take a picture of your receipt, it neatly records when, where, and for how much you bought the same item, and automatically retrieves and displays this information before your next shopping trip.

▸ One receipt makes one page of price records
When you take a picture of a supermarket receipt with your camera, the item name, unit price, quantity, store, and date are automatically separated and saved. There is no need to manually transcribe the information, and the results can be easily edited at any time.

▸ See when, where, and for how much you bought the same item at a glance
It compiles past purchases of the same item and displays the median, lowest, and highest prices together. Price changes by store are also organized into a graph on a single screen, allowing you to gauge at a glance whether today's price is truly cheap.

▸ Past prices in your pre-shopping cart
If you write down your next shopping list in advance, the lowest past price and recent purchase price are automatically attached to each item. You can simply check off items while grocery shopping.

▸ Add frequently purchased items to Favorites

You can check the price trends of items added to your Favorites directly from the home screen.

— Key Features —

• Input receipts via Camera/Gallery (manual input also supported)

• Automatic item separation using OCR + AI parsing

• Price history, store comparisons, and graphs for the same item

• Pre-loaded cart + automatic display of past prices

• Item normalization (grouping identical items with different names into one)

• Display formatted for Korean Won and Korean receipts

— Optimized for Korean grocery store receipts —

Currently, we prioritize support for major Korean supermarkets (E-Mart, Homeplus, Lotte Mart, Costco, etc.) and Korean-language receipts. Accuracy may be lower for receipts from other countries.

— My data on my device —

Receipt data is stored on the user's device. Receipt photos briefly pass through the server for automatic organization, but they are not stored once processing is complete.

This is not a household account book app. This app is less about organizing receipts and more about "not making the same mistakes on your next shopping trip."

Please send inquiries and feedback via the "Contact Us" option in the app settings screen. As this is our first launch, we will incorporate your feedback quickly.
