Our honesty commitments
Almost every nutrition app promises "accurate AI" without showing numbers. We publish exactly what we know, what we don't, and what we still need to improve.
We publish our real accuracy
Instead of saying "AI-powered" we show the numbers: our scanner’s average error (MAPE and MAE, in calories and in grams) against a small set of reference dishes (photos with the value on their label or a standard USDA or BEDCA portion, not dishes weighed on a scale), refreshed weekly. If a model version gets worse, you'll see it there.
See accuracy →Every medical claim is sourced
We don't say "studies show" without naming the study. Every calorie figure, every macro recommendation, every formula comes from USDA, BEDCA, EFSA, peer-reviewed journals, or WHO. The sources page lists them all with direct links.
See sources →Your data is yours
We don't sell to third parties. We don't use your data to train our model unless you tell us to (explicit opt-in, not pre-checked). You can export everything (JSON, plus meals and weight as CSV) or delete your account from Settings, and deletion is real, photos included: not a soft-delete.
See privacy →When we don't know, we say so
Every analysis has a visible confidence level (verified / estimated / approximate) and, under the number, its calorie range (“320–450 kcal”), because a photo can't give more precision than that. If a scale reference is missing, we tell you to add a fork to the next photo; if we're unsure what a food is, we ask you.
We don't hallucinate food
The scanner applies hard anti-hallucination rules: if the model sees artichokes and anchovies, it does NOT add ham “because they usually go together”. A second model, from another company, looks at the same photo on its own when it answers in time; if they disagree, or the plate is doubtful, the portions get a second pass. Then USDA validation and a physical cap per container. It still gets things wrong sometimes: that's why every result can be corrected.
No engagement bait
We don't game notifications to force your open. No streaks that artificially break, no fake countdowns, no lying "best price now" tags. Health isn't sold with FOMO.
