Nutriglance is a calorie tracker you use in a browser. You photograph a meal or describe it in words, and it estimates the calories and macros. Searched foods are looked up in USDA FoodData Central and Open Food Facts; a photo estimate is produced by the model itself.
Articles are written by the team, drafted with AI assistance and checked by a person before publication. Nobody here is a dietitian, and nothing on this site is medical advice.
What the product actually does
Specificity matters more here than enthusiasm, so here is the honest list.
- Estimates calories and macros from a photograph of a meal.
- Does the same from a written description — "two eggs and a slice of rye toast".
- Food search backed by USDA FoodData Central and Open Food Facts.
- A food diary with daily calories, protein, carbohydrate and fat.
- A water tracker, and reminders by email or Telegram.
- An AI assistant for nutrition questions. It is a language model, not a person.
- A plan for coaches who want to see their clients' diaries.
- Free calorie, TDEE and macro calculators that need no account at all.
What it does not do
Every one of these is something a reasonable person might assume we have. We do not.
- No barcode scanning.
- No Apple Health, Fitbit or Google Fit integration.
- No medication or GLP-1 dose logging.
- No meal planner or menu generator.
- No micronutrient tracking — the diary holds calories and the three macros.
- No data export for users yet. You can delete your account and everything in it.
We list these because we would rather lose a sign-up than have someone find out after registering. If one of them is essential to you, the comparison page says which apps do have it.
Where the numbers come from
| Path | Source of the figures | Can you check it? |
|---|---|---|
| Food search | USDA FoodData Central (public domain) and Open Food Facts (Open Database Licence) | Yes — both are public |
| Typed description | Produced by the model, with no food database lookup in that path | No — which is why it is an estimate |
| Photo estimate | Produced by the model, no database lookup in that path | No — which is why it is an estimate |
| Calorie and macro calculators | Mifflin–St Jeor, Harris–Benedict (Roza & Shizgal 1984), Katch–McArdle | Yes — the working is shown on each page |
We wrote up the limits of the photo path in full on how accurate AI calorie counting is, including why we do not publish an accuracy percentage.
How these articles are made
Plainly, because you would reasonably wonder.
- Topics are chosen where the honest answer was scattered across forums and videos and nobody had written it down properly.
- Drafts are produced with AI assistance and edited by a person before publishing. The byline is the team, not a model — we are responsible for what is here either way.
- Numbers are taken from named public sources, most often USDA FoodData Central, and rounded rather than invented. Where a figure is an estimate we say so.
- Claims about other apps are checked against those companies' own pages and dated on the page, so you can see how stale they are.
- Claims about our own product are checked against what the software actually does. We have removed several from this site for failing that test.
What we will not publish
- No invented experts. Nobody on this team is a registered dietitian, and we are not going to put a fake credential under an article to look more authoritative.
- No accuracy percentages we have not measured under a protocol we would hand to someone else to check.
- No before-and-after photos, no testimonials we commissioned, no star ratings of ourselves.
- No diet plans and no medical advice. A calorie tracker is not qualified to give either.
- No comparison that we always win. The comparison pages say what the other app does better, because a comparison without that is an advertisement.
Corrections
If something here is wrong, tell us at support@nutriglance.com and we will fix it and say on the page that we did. Articles carry a published date and an updated date for the same reason.
Not medical advice. Everything on this site is general information about counting calories. It is not a diagnosis, a treatment or a diet prescription, and it is not a substitute for a doctor or a registered dietitian — particularly if you are pregnant or breastfeeding, under 18, or managing a condition affected by what you eat. See the full health disclaimer.
You can earn the full version instead of paying for it
If any of the above sounds like the way you would want a tracker to behave, the free plan is the cheapest way to find out — no card, and no end date.
- Create an account and log a few meals. New accounts open with a two-day Plus trial — three days if somebody invited you — and then settle onto the free plan: no card, no end date, one meal scan a day.
- Publish an honest post, story, write-up or short video about what you found — or invite three people who go on to actually use it.
- Send us the link. A published piece unlocks the higher tier; three qualified invites unlock 90 days of the full version.
