Standing in the shop holding it? Scan it.

The Guru Index app reads the label on the product in your hand and shows you what the world's most trusted skincare experts have said about it. Free, for iPhone, no account needed.

It installs through TestFlight, Apple's own early-access app, which is where it lives while the App Store version is in review. One tap, nothing to sign up for.

Three seconds, in the aisle.

You are in front of a shelf with forty moisturizers on it and no way to tell which ones anybody credible has actually tried. That is the whole problem this solves.

Photograph the front

Point the camera at the label. No barcode to find, no typing, and the photo is used to read the label and then discarded.

See the Guru Score

If we hold the product, you get its Guru Score straight away, as a percentage, with the number of experts it is built from.

Read the actual takes

One tap opens the full verdict, where every take is quoted and attributed to the expert who said it, with the date.

What is behind the score

The Guru Score is not our opinion. We follow the skincare experts people actually watch, among them dermatologists, cosmetic chemists and estheticians, and we go through what they say about specific products in their own videos.

The score is our read on how warmly they talk about a product, not a simple thumbs up or down. An unreserved rave counts for more than a lukewarm "it is fine, but it is pricey". A product a dozen experts have weighed in on counts for more than one that two people liked. When the experts are split, the score sits in the middle rather than hiding the disagreement.

The app is reading the same index as this website, so it is as current as the site is, and it gets more products every night without you updating anything.

What is in the index

The app carries all of it, not a sample: more than 42,000 individual expert takes, each one attributed and linked to the moment in the video it came from. If we hold a product, the scan finds it. If we do not, the app says so plainly and shows you what we hold from that brand instead, which is usually the more useful answer on a shelf.

50 expert reviewers

Dermatologists, plastic surgeons, estheticians and cosmetic chemists.

4,100+ products scored

Skincare and beauty, each with the expert takes shown underneath.

950+ brands covered

From the household names to the ones only the experts talk about.

We show our working

The same rules the website runs on, because it is the same index.

Every take is quoted

Not summarised into a verdict you cannot check. You read what the expert said, and you can open the video at the moment they said it.

Sponsored takes are labelled

A take given in a paid partnership stays on the page, labelled, and counts for half as much. An expert reviewing their own brand is labelled too, and their take carries no weight at all in that product's score.

No brand pays us to score anything

Placement is not for sale. Being found, ranked or approved is not something a brand can buy.

Nothing to sign up for

The scanner is never behind a login. Signing in is optional, and it only exists so your wish list survives a new phone.

What the app is not

Not a medical service

Nothing in the app is medical advice. If a product or a skin concern worries you, ask your own doctor or pharmacist.

Not a shop

There is nothing to buy from us. Where a retailer link exists we show it, and we say when it earns us a commission.

Not our opinion

We review nothing ourselves. Every verdict in the app belongs to a named expert who said it in public.

Not watching you

The photo is read and discarded. There is no advertising tracker in the app, and what you scan is yours.
