How it works

Three steps to an honest label

No judgement, no diet plans. Just the same nutrition information, recalculated for the real world.

Find your product

Search or scan any food or drink. We start from the manufacturer's own serving size and nutrition data.

Tell us what you'd really have

Half the packet? The whole bottle? Slide to your honest portion and watch the numbers update instantly.

See the gap

Side-by-side gauges compare the official serving, your portion, and the community average — so you can see how everyone else answers too.

Community data

What do people actually eat?

Every honest answer makes PerBiscuit smarter. Together we're building the first picture of real-world portions — product by product, biscuit by biscuit.

Your answers are anonymous, and you'll see the community average the moment you add yours.

Our mission

We're not here to tell you what to eat. We're here to make the label make sense.

Serving sizes are often set by manufacturers, not by how people really eat. When the numbers on the front of the pack describe a portion nobody has, the label stops being useful. PerBiscuit closes that gap — with transparency, not guilt — so you can make informed choices about calories, sugar, salt and everything else.

When the label says one biscuit, what do you really eat?
