Every bite adds up.
Now you can see it.
Log each thing you eat and watch the day’s total for every contaminant build, with the food behind each jump.
Demo values are example category averages, not safety limits. Published products with parsed lab results show the analytes measured on their product detail.
Point the camera at each item to build today’s contaminant snapshot.
Log it once. Purus does the math.
Every meal adds up across your day and your week, for nutrition and contaminants at the same time.
Snap it, scan it or say it
Take a photo, scan a barcode or just describe what you ate. AI picks out each ingredient, and you confirm every portion before anything is saved.
See what’s in your day
Your total exposure, each metal’s 7-day average against its limit, and calories, macros and micronutrients against your own targets. Sources shows which foods drive each number.

How we keep it honest
Every estimate shows its evidence
Each number in the app says how many lab samples it rests on, so you can see how solid it is.
Limits scaled to you
Health-based limits, adjusted for your body weight and the level of caution you choose.
Real results beat averages
When a brand publishes lab results for a product, they replace the category average, labelled with who stands behind them.
Purus gives estimates for general information. It is not a medical device and does not diagnose, treat or prevent any condition.
A week of meals built around your limits.
Purus Pro plans 21 meals around your diet, allergies, calorie target and contaminant limits, then writes the grocery list.
- See the whole week’s projected exposure before you shop, with swaps and planned leftovers
- Keep the meals you like and re-plan the rest, cook in batches, or plan just the rest of this week
- A grocery list with amounts, plus organic picks where pesticide residues run highest
- Log any planned meal with one tap
- Omnivore

Two ways to prove
what’s really in it.
When a brand joins Purus, their verified results replace our population averages, so shoppers see the truth for that exact product.
Bring your own COAs.
Brands upload their own certificates of analysis. We read the results and show them on the product page and in-app, with the date each lot was tested.
- ✓ Brand-submitted lab certificates
- ✓ Results read straight from your COA
- ✓ Ingredient & sourcing disclosure
- ✓ Marked “Brand-submitted” for shoppers
We test it ourselves.
Products are pulled and sent to accredited third-party labs, lot by lot. Results replace the averages with real numbers, and earn the Purus Certified seal.
- ✓ Independent, accredited lab testing
- ✓ Lot by lot, not one-and-done
- ✓ Real values replace averages in-app
- ✓ Certified seal across app & marketplace
What does Purus track?
Calories, protein, carbs, fat and key vitamins and minerals, plus your estimated exposure to lead, arsenic, cadmium, mercury, glyphosate and other pesticide residues. Each one is measured against a health-based limit for your body.
How does Purus estimate what’s in my food?
From lab testing of foods, combined into averages for each food category, and from a brand’s own lab results where it has published them. Every estimate shows how many samples it rests on, and limits are scaled to your body weight.
Is Purus free?
Yes. Daily tracking is free. Purus Plus adds trends and your full history, and Purus Pro adds weekly meal plans and grocery lists. Both are optional App Store subscriptions.
How does Pro keep a week of meals under my limits?
Pro builds 21 meals around your diet, allergies and calorie target, projects the whole week’s exposure before you shop, and swaps meals that would push a metal past its weekly limit. Metal limits are long-term averages, so one high day is fine when the week stays under.
Is Purus medical advice?
No. Purus gives estimates for general information. It is not a medical device and does not diagnose, treat or prevent any condition. Talk to your doctor before making medical decisions or major changes to your diet.
I run a food or supplement brand. How do I get listed?
Create a free brand account, add your products with their barcodes and upload your certificates of analysis. Transparent adds benchmarking and the right to publish claims; with Certified, we buy and test your products ourselves.
