Best Skin Analysis App for iPhone: 7 Selfie Scanners Compared

The best skin analysis apps for iPhone are Skan, Pori and Trace. Skan is best overall because it has the most ratings of the selfie scanners we compared, 4.8 stars from about 9,800, covers acne, redness, pores, pigmentation, wrinkles and eye bags, and was updated in November 2026. Pori, which we make, is the pick if you want scores tied to a sleep, water, stress and diet diary, and Trace is the best free and most private option because it scores your skin on the phone itself.

If you also want to check what you put on your skin, you can scan a product's barcode or label with the ingredient scanner in Pori to check it against your skin type. Pori is a cosmetic app and does not diagnose skin conditions.

This comparison is about what matters on an iPhone specifically: which iOS version each app needs, whether your photo leaves the phone, what the free version gives you and what the subscription costs. We read every app's US App Store listing in November 2026 and did not test the apps on skin. For the wider market, including Android and medical apps, see our AI skin analysis app comparison.

Quick picks

• Best overall: Skan (free, premium $1.99 to $39.99, App Store) - the most-rated selfie scanner here, with product checks and progress tracking.
• Best for linking skin to habits: Pori (first scan free, Pro $9.99/week or $49.99/year, App Store) - five category scores, skin age and a lifestyle diary.
• Best free and most private: Trace (free, no in-app purchases listed, App Store) - four scores measured on your iPhone, so scanning sends no photo.
• Best budget subscription: GlowScanAI ($24.99/year, App Store) - the cheapest yearly plan, if you have iOS 18.2 or later.
• Best for older iPhones: Glow ($4.99 to $69.99, App Store) - runs on iOS 15.1 and has a 4.8 rating from about 2,200 ratings.
• Best for products and routines: Skin Bliss (Pro $6.99/month or $34.99/year, App Store) - a large product database and ingredient compatibility checks.
• Best for acne: Skinsign ($4.99 to $59.99, App Store) - acne, redness, texture and hydration scores plus trigger tracking.

How do the best iPhone skin analysis apps compare?

Ratings, iOS requirements and prices are from each US App Store listing as of November 2026. "Where scoring runs" is what the listing or privacy policy says; most don't say.

Does the iPhone make skin analysis more accurate?

Not in the way you might hope. Every app here works from an ordinary selfie, and none of the listings says it uses the TrueDepth camera's depth data to measure skin. Depth helps map the shape of a face and says little about pores or color, as our guide to face scanner apps explains. What the iPhone does change is how the photo is processed. Photographic Styles, Portrait Lighting and filters can smooth or warm your skin before an app sees it, so use Photo mode with a standard style and the flash off. Our iPhone camera settings for skin photos walks through each setting.

Consistency matters more than the app. Scan bare-faced, facing a window, at the same time of day. Read weekly trends; single scores are noisy. If you want to know how much a score can move between two scans, read why skin analysis results change.

The apps, one by one

Skan: best overall

Skan takes a selfie and describes visible concerns including acne, pores, redness, dark spots, pigmentation, wrinkles and eye bags, then saves scans so you can compare progress. It adds a routine builder and ingredient insights. It had a 4.8 rating from about 9,800 ratings in November 2026.

Who it suits: people who want one app for scans and shopping. Who should skip it: anyone who wants everything free; the product finder and product scanner need Skan Premium. The catch: its App Store privacy label lists data that may be used to track you, and the listing doesn't say where scans are processed.

Pori: best for linking skin to habits

Pori is our app. A selfie takes about 10 seconds and returns a 0 to 100 score with five categories, plus a skin-age estimate. A skin diary logs sleep, water, stress and diet so you can see them next to your scores, and there's before-and-after comparison, progress charts, a home-screen widget with your score and streak, and an AI chat that uses your scan history. The Pro ingredient scanner flags each ingredient as beneficial, use with caution or avoid for your skin type.

Who it suits: people who want to see which habits line up with changes in their skin. Who should skip it: anyone who wants a dedicated acne score, which Skinsign and Trace have. The catch: Pori is new and had no App Store ratings yet, it's in English only, and the weekly plan costs more than rivals, so the yearly plan is the better deal. Photos are sent over HTTPS for analysis and aren't kept on our servers after the result. Our privacy label lists identifiers that may be used to track you, so read it as you would anyone else's.

Trace: best free and most private

Trace turns a daily selfie into four scores from 0 to 100 (acne, redness, pores and spots) with a trend line for each. Its listing says scores are measured on your iPhone, so scanning never sends your photo anywhere, and optional AI features send a photo only when you use them. It encourages one change at a time and reading results over weeks. The catch: it's new, with 13 ratings, and it doesn't score hydration or aging. Our explainer on on-device vs cloud skin analysis covers the trade-offs.

GlowScanAI: best budget subscription

GlowScanAI scores wrinkles, texture, redness, dark spots and pores, estimates skin age and builds morning and evening routines, for $8.99 a month or $24.99 a year. The catch: it needs iOS 18.2 or later, which rules out older iPhones, it has only a handful of ratings, and the core features need a subscription.

Glow: best for older iPhones

Glow rates hydration, texture and other categories, builds a routine, recommends products and compares before-and-after photos. It runs on iOS 15.1 and had a 4.8 rating from about 2,200 ratings. The catch: its last update was in September 2025, and some App Store reviewers say you have to subscribe to see results after a scan.

Skin Bliss: best for products and routines

Skin Bliss is strongest on products, with a face scanner, routine builder and ingredient compatibility checks. Pro is $6.99 a month or $34.99 a year, and it also lists a $1.99 face scanner purchase. Read our Skin Bliss review for how fair its product picks are. The catch: the face scanner is a smaller part of the app than the product tools.

Skinsign: best for acne

Skinsign scores acne, redness, texture and hydration, logs food, sleep, stress and water, and looks for patterns between your habits and your skin. It had a 4.7 rating from 217 ratings. The catch: it's an acne coach more than a general skin analyzer. Compare it with other options in our best apps for acne and acne tracker guides.

What should you check before you subscribe?

• Your iOS version. Settings, General, About shows it. GlowScanAI needs iOS 18.2; Pori and Trace need iOS 17.
• What's free. Some apps show results only after you pay. Our free skin analysis app guide lists what each gives away.
• The privacy label. Scroll to App Privacy on the listing and look at "Data Used to Track You." Apple notes labels are the developer's own answers. Our skin app privacy guide explains what to look for.
• How the trial ends. App Store subscriptions renew automatically unless you cancel at least 24 hours before the period ends. Apple explains how to cancel a subscription on iPhone.
• What it can't do. None of these apps checks moles or diagnoses conditions. For a changing spot, see a dermatologist; our AI dermatologist app guide covers apps that connect you with one.

How we chose

We searched the US App Store for skin analysis and skin scanner apps and kept iPhone apps that score your face from a selfie and are still updated or widely used. For each one we read the November 2026 listing for features, ratings, minimum iOS version, in-app purchase prices and privacy label, and used the listing or privacy policy to see where scoring runs. We favored apps that say clearly what they measure, what's free and what they can't do. We did not test the apps on skin, and scores from any of them shift with light and angle. Pori is our app, so weigh our view of it accordingly. Nothing here is medical advice.
