Know what you eat.
Understand what you need.
Scan the product, set the portion, and Fitizen shows how it fits your day — not an average, but yours.
Open beta in preparation. We ask for an email address, nothing else.
The label becomes a diary entry, and that becomes the next step.
Range 240–290 kcal.
It recognises what you see on the label.
From a barcode or a photo of the nutrition table. The AI reads it, you check it — the result is editable.
An AI estimate and a value read from the label are not the same thing — here you always see which is which.
Not just a log — it shows the connection.
Your day is a timeline: when, what, how much — and what is still missing from your budget.
The three strands of the Flowline are energy, protein and fibre. As the day goes on, they move closer together.
It shows what still fits.
Not a banned list: one item, a simple combination or your own recipe.
Over time it learns your own energy needs.
We start with an established formula, then your own weight and intake trend refines the range.

Activity is not a magically precise calorie bonus. The value from WHOOP is estimated, not measured.
Your data, with a visible source.
- Source and certaintyFrom the label, AI estimate, database or your own entry — you always see which.
- Machine-readable exportYour diary can be downloaded, it doesn’t get stuck — and other tools can process it.
- Deletion confirmedYou follow it through, and we tell you when it’s done.
- WHOOP, if you wantOff by default; you decide what comes across.
For us, privacy is a concrete property, not a slogan.
What it’s built on
Fitizen is a general wellness and fitness product. It is not a diagnostic device, does not treat disease, and does not replace professional advice.

We’ll tell you when the beta starts. Nothing to do until then.
