Penaria

Know what you'll pay,
before you shop.

Scan your grocery receipts and Penaria learns your prices: which store wins for your basket, what's quietly getting expensive, and what you'll likely spend before you walk in.

How it works
01 · SCAN

Any receipt counts

Photograph paper receipts, or share images and PDFs straight from Mail, Photos, or Files. Old receipts from the drawer work too - your price history starts today, not next month.

02 · LEARN

Your prices, not averages

Milk is what you pay for milk, at your stores. Penaria tracks every price you've actually paid and tells you, in plain language, when something moves.

03 · DECIDE

Before you go, and in the aisle

Plan a trip and Penaria estimates your basket at each of your stores. In the aisle, scan a shelf tag to see if a price is good for you. When one store clearly wins, it says so. When it's too close to call, it says that instead.

Honest by design

An app that admits when it doesn't know

Estimates are labeled as estimates. Misread prices get flagged as "check price" instead of headlining your month. And Penaria grades its own predictions against your next receipt, then shows you the score:

Estimate accuracy · graded against your own receipts
Every prediction is scored against your next receipt, on your account. If the app is wrong, it tells you exactly how wrong.

Optional, anonymous, zip-level

See how your prices compare with what shoppers near you are paying. Contributions carry a zip code and a price - never your name, your account, or your location. Turn it off any time in one tap.
