Tanu — Know if it's a good deal, instantly

How it works

Three taps from shelf to verdict

No spreadsheets, no mental math. Tanu does the €/kg comparison for you.

1

Scan

Point your camera at any barcode. Tanu pulls the product from Open Food Facts in a second.

2

Compare

It converts the price to a unit price and checks it against the community's price history.

3

Decide

You get a clear verdict — good deal, average, or expensive — so you buy with confidence.
