Honey Roasted Oats Cereal
Post
Stricter because this shopper watches seed oils and ultra-processing.
Olive Detective saysLooks wholesome, but it's an ultra-processed cereal built on refined grains and a sugary honey glaze — a quick spike, then a mid-morning crash. A plainer oat with no added sugar would score far higher.

Seed-oil radar
We flag 11 seed oils — canola, soybean, sunflower, corn and the rest — the moment they show up in the list.
Additives & processing
Controversial E-numbers, added sugar, sodium and NOVA ultra-processing level, each broken out on its own card.
Detected Toxins
Category-level contaminant flags anchored to FDA monitoring — heavy metals tied to cocoa (cadmium, lead) or large fish (methylmercury), and more. Precautionary and capped at a caution, never an alarm.
Smarter swaps
We don't just flag the bad — we suggest real, better-scoring alternatives from the same shelf, filtered to your diet.
Allergens, your way
Set your allergens once and they get highlighted in red on every scan. Gluten, dairy, soy, nuts, shellfish and more.
Cosmetics, not just food
Scan skincare and makeup too — we auto-detect a beauty product and flag parabens, fragrance, and endocrine disruptors, same clean 0–100 score.
Pet food, scored too
Scan dog and cat food and we flag meat by-products, fillers, artificial dyes and truly toxic ingredients like xylitol — with a species-aware score for your pet.
Seed-oil-free dining map
Find restaurants near you that cook with clean fats, color-coded by how confident we are about their oils.
FDA recall alerts
A live feed of US food recalls, plus a warning banner if something you scanned is affected.
Real results at the grocery shelf.
It's not about fear — it's about finally being able to see what you're buying and choosing better in seconds.
Nutritional clarity
No more decoding tiny labels. One score and a plain-language summary tell you where a product stands.
Proactive filtering
Set what you want to avoid — allergens, seed oils, additives — and every scan is checked against it for you.
Better choices, faster
When something falls short, a cleaner swap is one tap away — so a healthier cart doesn't take longer.
Don't just avoid the bad — find the better.
Scan a product, and if it falls short we surface a cleaner, better-scoring alternative from the same shelf. Here's a real one.
Classic Potato Chips
Lay's
Stricter because this shopper watches seed oils and ultra-processing.
Olive Detective saysDeep-fried in refined seed oils and so ultra-processed there's barely real food left. There's a much cleaner swap on the right.

Kettle Cooked Chips
Siete
Stricter because this shopper watches seed oils and ultra-processing.

A score you can actually trust.
Most scanners guess, punish natural food, or hand you a different number every time. Ours is a deterministic engine that weighs three things — nutrition quality first, then additives and processing — and is tuned so whole foods like olive oil, nuts and cheese are never penalised for the fat or salt that's naturally theirs. Same product, same score, every time — and every claim links to its source.
And a second score — just for you.
Tell us what you're avoiding — seed oils, added sugar, additives — and every product gets a second, personalized “For You” score, re-weighted toward what you actually care about. The same snack can be a hard skip for you and perfectly fine for someone else.
Find seed-oil-free restaurants near you.
Eating clean shouldn't stop at your front door. Our map shows restaurants that cook with clean fats — olive, avocado, tallow — color-coded by how confident we are about their oils, updated as you explore.
- Real-time GPS with an 8km radius you can expand
- Markers color-coded by cooking-oil confidence

Olive Detective reads dog and cat food the same way it reads yours — no separate app, no mode to switch. Scan a pet-food barcode or the ingredients label and get a 0–100 score with by-products, fillers and truly toxic ingredients called out in plain language.
- Auto-detects pet food on every scan — Open Food Facts, then Open Pet Food Facts, then the label itself

- Species-aware: catches cat-only hazards like propylene glycol, and suggests cleaner, better-scoring food
Ingredient risk is class-level and precautionary, not veterinary advice — some flags are species-specific (e.g. propylene glycol is a cat-only red flag).
Built to fix what other scanners get wrong.
Most food scanners punish natural food, hand you a different score every time, and never show their work. We do the opposite.
Real mothers. Real results.
“I scan everything before it goes in the cart now — food and my skincare. Finding out my 'healthy' granola was mostly seed oil and sugar was the wake-up call I needed.”
Real mothers. Real results.
“Standing in the aisle I used to just guess. Now I scan and know in two seconds whether it's actually clean or just clever packaging — then it points me at a better option on the same shelf.”
“As a new mom I read every label anyway. Olive does it faster and catches the seed oils, additives and allergens I'd have missed. It's like a second set of eyes on everything my kids eat.”

Questions, answered.
Olive Detective is a food, cosmetic and pet-food scanner app for iPhone and Android that scans grocery, personal-care and pet-food barcodes to return a 0–100 score — flagging seed oils, additives and allergens in food, parabens, fragrance and endocrine disruptors in cosmetics, and by-products, fillers and toxic ingredients in dog and cat food — then suggests cleaner swaps, using transparent scoring that never penalises whole, natural foods.
Olive Detective comes with a 7-day free trial — full access from the first scan. Cancel anytime before it ends and you won't be charged. After that it's $49.99/year (about $4.17/month).
From Open Food Facts, an open database of 2M+ products, plus our own scoring on top. When a barcode isn't found, you can scan the ingredients label directly.
It's a deterministic engine that weighs three things — nutrition quality first, then additives and processing (NOVA) level — with a small organic bonus. Whole, natural foods are never penalised for the fat or salt that's inherent to them, and the same product always returns the same score. Set what you're avoiding and you also get a personalised “For You” score re-weighted to you.
Yes — we flag 11 common seed oils the moment they appear in an ingredient list, along with additives, added sugar, sodium and processing level.
Yes — Olive Detective surfaces a category-level “Detected Toxins” read anchored to FDA monitoring, such as the heavy metals associated with cocoa (cadmium and lead) or large fish (methylmercury). These are precautionary, category-level cautions based on the product's food category — never a claim that a specific item contains a specific amount.
Yes. Olive Detective auto-detects whether you scanned a food or a personal-care product — no mode to switch. Cosmetics get a 0–100 score too, with parabens, fragrance allergens, formaldehyde-releasers and other endocrine disruptors flagged from the INCI ingredient list, plus cleaner swaps. Ingredient risk is class-level and precautionary, based on EU CosIng, SCCS opinions and IARC.
Yes. Olive Detective auto-detects pet food and scores it 0–100 with a deterministic hazard/quality method — flagging meat by-products, fillers, added sugar, artificial dyes and preservatives like BHA/BHT, and truly toxic ingredients such as xylitol, onion and garlic. It's species-aware (some hazards, like propylene glycol, apply only to cats) and suggests cleaner, better-scoring food. Class-level and precautionary — not veterinary advice.
Absolutely. Set your allergens and dietary preferences once and every scan is tailored to you — allergens flagged in red, and swap suggestions that respect your diet.
Scores are computed the same way every time from published nutrition data and ingredient lists — no guesswork and no random swings. Every insight links to its source so you can check the reasoning yourself.
