"Unplug that clock, boy. You can't see the time while you're sleeping."
"If I don't buy anything, the discount is bigger."
"It's two cents an hour, boy. Two cents!"
— Julius Rock
Julius would tell you this. But he went to work.
Julius knows the price of everything that enters your house. He calculates. He compares. He doesn't accept paying more for less.
Most people aren't like that. Most leave the market without knowing, truly, where the money went.
And it's not for lack of attention. It's because nobody shows you.
The package looks the same. But it shrunk 200g.
This is called shrinkflation — and it happens every week, with dozens of products, without any warning on the shelf.
The weight trick
The 200g yogurt became 170g. The 5kg rice became 4.5kg. The price on the tag? Same. Sometimes even a bit lower.
More for less
In practice, you're paying more for less. And the supermarket is betting that you won't calculate.
Frugi calculates
We monitor the price per kg or liter. If the package shrunk, the app alerts you at the time of the scan.
"How do you forget money that came for free? I remember every cent I've ever found."

The assistant that goes to the market with you
It's not a generic finance app. It's an intelligent scanner that understands what you buy.
Smart Scanner
Point the camera at the label. Frugi reads, records, and compares with the history. If the price went up — or if the weight changed — you see it instantly.
Dashboard of Truth
Each purchase becomes an automatic report: how much you spent, which market is more expensive, and which products suffered shrinkflation.
Data is Yours
No Frugi server stores your purchases. The history stays on your phone and in your Google account. Your data, your control.
From scanning to the dashboard in less than a minute

What happens when you really start looking
"I went to buy my usual milk. Frugi warned me that the price per liter had gone up 14% — but the packaging looked the same. I looked closely: 1 liter had become 900ml. I switched brands. Saved $8.40 on that purchase."

"In three months of Frugi, I discovered I was spending $280 more per month at the same old market vs the wholesaler on the other side of town — for the same products. I had never truly compared before."

"The best thing is knowing my data is mine. The spreadsheet stays in my Google Drive. If the app closes tomorrow, my history stays there."

Questions you probably have
Do I need to create a new account?
No. Login is done with your Google account, which you already have. No registration, no new password.
Where does my data stay?
On your phone and in your Google account. Frugi literally doesn't have access to what you buy. We don't store anything on our own server.
Does it work without internet at the market?
Yes. The scanner processes everything locally, on the phone itself. Synchronization with Google Drive happens when you have a connection.
What if I change my phone?
Log in with your Google account on the new device. Your purchases appear automatically. Nothing is lost.
What is shrinkflation?
It's when a brand reduces the weight or volume of a product while keeping the price on the tag. Frugi calculates the price per kg or liter and alerts you.
Julius wouldn't let a single cent pass. Would you?
