Protein Energy — the protein density of any packaged food, in one number.
Scan a barcode and get the P:E ratio = protein / (carbohydrates + fat).
It shows how much of a food is protein rather than energy-dense macros, something a calorie count alone doesn't tell you.
Mozzarella scores 0.94. Pesto scores 0.08. Same shelf, very different foods.
Every scan gives you
• The P:E ratio, calculated per 100 g
• Energy, fat, carbohydrates and protein
• Ingredients, product photo, and Nutri-Score and NOVA group where available
A history that stays useful
• Every scan is saved, searchable by name or barcode
• Sort by name, P:E or kcal to compare what you've scanned
• Step between products with the next and previous arrows
• Anything scanned before opens instantly, even with no signal
No account, no tracking
Your history never leaves the phone. There's no sign-up, no analytics, and nothing is uploaded. The camera is used only to read barcodes.
About the data
Product information comes from Open Food Facts, a free and open database maintained by volunteers under the ODbL licence. Coverage of
common European groceries is good but not complete, some products aren't listed, and some lack the figures needed to calculate a ratio.

Protein Energy is a tool for reading labels, not dietary advice.
