Lumy for everyday household spending
A grocery price tracker built from your own receipts
Your receipts become a personal price history, so familiar products are easier to compare over time.
Headline inflation figures describe an average basket, not yours. The only reliable record of what your family pays for milk, coffee or nappies is the receipt; a bank statement shows just the total. Lumy reads the individual product lines on scanned receipts and keeps them, so each product you buy repeatedly gains its own price history, at the shops where you actually bought it.
How it works in Lumy
- 1
Scan the receipt after shopping
Lumy reads the merchant, date, total and each product line, including discounts and deposits. You check the result before it is saved.
- 2
Let the history build up
Every scan adds prices for the products on it. After a few weeks of regular shopping, repeat purchases start to show a trend.
- 3
Check Opportunities
Lumy flags products that got more expensive and places where you paid more than before, based on your own history.
- 4
Plan the next shop
Add products to a shared shopping list and it shows an approximate total from the prices you paid last time.
Built for daily life
Know when prices creep up
Every receipt you scan builds a personal price history. Lumy flags anomalies, charts product price trends across the stores you shop at, and surfaces your true repeat-purchase basket. Pro only.
Receipt scanning
Attach a photo of a receipt — up to five at once — and Lumy reads the amount, merchant, and date, then records it for you.
Set limits. Know when you're close.
Create category-based budgets for the week, month, or year. Lumy tracks your spending in real time and warns you before you overspend.
Is this the right setup for you?
A good fit if
- You shop at the same supermarkets and buy many of the same products every week.
- You want to know which products push your grocery bill up, not a national average.
- You keep paper receipts, including long ones from a big weekly shop.
Probably not for you if
- You want live shelf prices or deals from shops you have not visited; Lumy does not read shop websites.
- You rarely keep paper receipts.
How it compares with the usual alternatives
Price-comparison and deal apps
Show current prices from retailers' catalogues. Useful before a shop, but they do not know what you bought or what you paid.
A spreadsheet of prices
Works if you type every line by hand. Few people keep it up past the second week.
Bank statements
Show one total per shop visit, so a price rise on a single product disappears inside the total.
Questions people ask
Does Lumy know current prices in shops?
No. Everything comes from receipts you scanned, so prices are what you paid at the time. Treat them as history, not a quote.
Which receipts can it read?
It is built for real European receipt layouts, including Latin and Cyrillic text, decimal commas and long receipts photographed in several parts. Every scan is shown for review before saving.
Is price tracking free?
Receipt scanning and Opportunities are Pro features. The free plan covers manual tracking and budgets.
How many receipts before trends appear?
It depends on how often you buy the same products. Weekly staples show movement after a few shops; occasional purchases take longer.
Can my family plan the shop together?
Yes. Shopping lists belong to the family group, so everyone edits the same list and sees changes as they happen. Family sharing is a Pro feature.
