Label and barcode scanning
Reads the ingredient list straight from the pack, or looks the product up by barcode.
New in 3.0: every feature, free
Know what's in your food, and whether it suits you.
Point your camera at an ingredient label or barcode. PuristIQ checks it against your health profile (allergies, intolerances, diets and conditions) and flags what may not suit you, with a short reason for each.

How it works
Three steps, a few seconds
-
Tell it what matters to you
Turn on the profiles that fit: allergies, intolerances, diets, health conditions. Add your own if something is missing, and a separate one for your pet.
-
Scan the label or barcode
Aim at the ingredient list or the barcode. Text is read on your phone, in the label's language or yours.
-
See what to watch for
Ingredients that may not suit you are flagged, each with the profile it conflicts with and a short explanation. Then check the printed label.

Privacy first
Your health data stays on your phone
What you eat and what you're sensitive to is nobody else's business. PuristIQ is built so it never has to know.
-
No account, no sign-up. Open the app and scan.
-
No ads, analytics or tracking SDKs. No advertising ID, no device identifier sent anywhere.
-
Profiles, lists and history stay on the device. Backup is optional and goes to your own iCloud or Google Drive, encrypted.
-
AI label reading is opt-in. Only the label photo is sent, it is processed in memory and not stored. Never your profile.
-
Contributions are opt-in and anonymous. Off by default. If you turn them on, only items you create or categorise yourself are shared: custom ingredients, custom products and the barcodes you link to them.
Free for everyone
How PuristIQ is funded
Safety information shouldn't sit behind a paywall. Since version 3.0 every feature is free for everyone: no Pro tier, no credits, no ads, and no data to sell.
PuristIQ is made by NousVigil LLC, and we don't accept money from food brands. It is kept going by people who choose to chip in. Tips are optional and unlock nothing.
A decision aid, not medical advice. PuristIQ can misread a label or miss an ingredient, and recipes change. Always check the printed label, and follow your doctor's or dietitian's advice for allergies and medical conditions.
FAQ
Questions, answered
Is PuristIQ really free?
Yes. Since version 3.0 every feature is available to everyone: multiple profiles, pet profiles, custom ingredients and profiles, backup and AI label reading. There are no ads, no subscriptions and no in-app credits.
Then how is it paid for?
By people who choose to support it, outside the app. You can buy us a coffee or see other ways to help. A tip unlocks nothing, and the app works exactly the same whether you tip or not.
What does it flag?
Ingredients that may not suit the profiles you turn on: allergies (peanut, milk, gluten and more), intolerances, diets such as vegan or gluten-free, and a range of health conditions. Each flag names the profile it conflicts with and gives a short reason.
You can add your own ingredients and profiles when something you need is missing.
Is it medical advice?
No. PuristIQ is a decision aid. It can misread a label or miss an ingredient, and manufacturers change recipes. Always check the printed label and follow your doctor's advice.
What leaves my phone?
By default, only what a lookup you start needs, such as the barcode number to find a product. Your profiles, lists and history stay on the device.
Two things are optional and off until you turn them on: AI label reading (a single label photo, processed in memory and not stored) and anonymous contributions (custom items you create). Backup, if you enable it, goes to your own iCloud or Google Drive. Details are in the privacy policy.
Does it work offline?
Yes. Reading labels, your profiles and the ingredient database all work without a connection. Looking up a new barcode and AI label reading need internet.
Can I scan pet food?
Yes. Switch to Pet mode, create a profile for your dog or cat and add health tags such as a chicken or beef allergy.
Is there an iPhone app?
The iPhone and iPad app is in App Store review. The App Store button on this page will work as soon as it is live. PuristIQ is available on Google Play today.
Yes. PuristIQ is on the App Store for iPhone and iPad, and on Google Play for Android.
Which languages does it support?
The app and its ingredient database are available in 24 languages, and it recognises ingredient lists in many of them regardless of your phone's language.
