Barcode scans are free and unlimited. No barcode match? Photograph the ingredient list.
The phone reads the text itself first. Tap any ingredient to fix a misread before you see a result.
Every flag names the ingredient, explains the reason in plain words and links to the official source.
Four answers, always with a reason
Official guidance says to avoid it while pregnant, such as topical retinoids or high-mercury fish.
Fine within a limit the guidance sets, such as 200 mg of caffeine a day or 4 cans of tuna a week.
Guidance is limited, or the label doesn't say what we need, like whether a soft cheese is pasteurised. We tell you what to check.
Nothing on our watch list. Not a promise that a product is safe: ingredients the guidance doesn't cover aren't on the list.
Made for the questions you actually have
Can I have brie? Is benzoyl peroxide okay? Type a food or ingredient and get the answer with its source.
Just found out? Scan the products on your shelf one after another and see them in one list, with what to look at first.
Carbs for the portion you actually eat, compared with the targets from your dietitian. Numbers come from the label, never estimated.
Saved products are flagged if official guidance changes their rating, so you hear about it without re-scanning.

Questions
No. Nest Scan gives information to help you check labels. It summarises official pregnancy guidance and links to it. Always check with your doctor or midwife, especially for medicines and prescription products.
A fixed list of ingredient rules taken from official guidance (NHS, ACOG, FDA and NHS maternity services), each linked to its source and checked on a stated date. The same label always gets the same result. The list has not yet been reviewed by a clinician, and the app says so on every ingredient page.
No. When the phone can't read a label clearly, an AI model only transcribes the ingredient list, and you can fix anything it misread. The rating always comes from the rule list, never from the AI.
None of the ingredients we could read are on our pregnancy watch list. It is not a promise that a product is safe, and ingredients official guidance doesn't cover are not on the list.
Your due date, diabetes answer and carb targets stay on your phone. There is no account or email sign-up. Label photos are only sent when the phone can't read the text, to Google's Gemini API to read it, and we don't keep them. You can delete everything from Settings in one tap.
Barcode scans, lookups and full results are free, with 3 label photo reads a day. The Pregnancy Pass is $29.99 once and covers 10 months with no auto-renewal. Yearly ($34.99), monthly ($6.99) and weekly ($2.99) subscriptions renew until you cancel. Your store shows the price in your currency.
In your iPhone Settings under your Apple ID and Subscriptions, or in Google Play under Payments & subscriptions. Cancel at least 24 hours before the renewal date. The Pregnancy Pass never renews, so there is nothing to cancel.
