About this app

When did I buy this? — A household ledger that organizes your records at a glance from the date of purchase until now.

You no longer have to look it up every time you wonder, "How long has it been since I bought this?"

Simply enter the product name, price, and purchase date, and it will automatically calculate and show you how many days or years you have used it up to today.

📦 Organize by Category

You can freely create categories of your choice, such as electronics, household goods, and clothing, and rearrange their order.

Manage items by family member or by purpose—as you see fit.

📅 Automatic Usage Duration

Just record the purchase date, and it will continuously calculate and display usage based on today, such as "Used for 1 year and 153 days."

You will get a sense of when it is time to replace items.

📊 View Expenses at a Glance

Check the proportion of spending by category on a pie chart and instantly see where and how much you have spent.

🗑️ It’s Okay to Delete by Accident

Deleted items remain in the trash, so you can restore them at any time. 💾 Back Up and Restore

Save your past records as files and retrieve them whenever needed.

🌙 Light & Dark

Change the screen theme to your liking.

No registration or login required.

All records are stored only on your device and are not transmitted anywhere.

It is a household account book that you can start with ease and use for a long time.
