App to Identify Skin Conditions: 6 Free & Paid Picks (2025)

You spotted a stubborn rash, a new mole that looks different, or your child’s skin has developed small, pearly bumps—and now you’re searching for an app that can tell you what it might be. The good news: phone‑based skin checkers are much better than they were a few years ago and can help you narrow possibilities fast. The catch: quality, accuracy, and privacy protections vary widely, and no app can give you a medical diagnosis. Used wisely, though, they’re great for triage, learning what to watch for, and deciding whether to seek care now or monitor over time.

In this 2025 guide, we compare six stand‑out options—free and paid—that identify skin conditions from photos: from fast rash checkers to mole risk assessors. For each pick, you’ll see how it works, who it’s for, pricing and platforms (iOS/Android), and the limits and privacy trade‑offs to know before you upload a photo. We’ll also point you to next steps if the result suggests something urgent. Ready to take a clear, confident first step? Let’s start with Aysa.

1. Aysa (VisualDx): fast rash checker

Aysa is a skin rash app powered by VisualDx that gives AI‑enabled guidance for common skin conditions. If you’re looking for an app to identify skin conditions quickly from a photo, Aysa is designed to narrow possibilities and suggest next steps without claiming a diagnosis.

How it works

You take a clear photo, answer a few short questions, and Aysa compares your image to visually similar conditions from the VisualDx library, then offers personalized guidance. It’s built for fast triage so you can decide whether to self‑care, watch and wait, or seek care sooner.

  • Snap a photo of the spot or rash.
  • Answer brief prompts about symptoms and duration.
  • Review look‑alike conditions and suggested actions.

Who it’s for

Great for parents checking rashes on kids, adults with new redness or bumps, and anyone who wants a quick, guided first pass before booking an appointment. Use it as a learning tool and triage assistant—not a substitute for a clinician.

Pricing and platforms

Aysa is offered as a mobile app. Specific pricing and platform availability aren’t listed on the Aysa site; check your device’s app store (iOS/Android) for the latest availability and any fees that may apply in your region.

Limitations and privacy

Aysa does not provide a medical diagnosis and focuses on common conditions; urgent or rapidly worsening symptoms warrant professional care. Because you’ll upload skin photos and symptom details, review the app’s privacy policy and permissions before use. Results depend on photo quality and lighting—retake images if they’re blurry, shadowed, or overexposed.

2. Google Lens skin search (free): find visually similar conditions

If you want a no-cost way to quickly narrow possibilities, Google Lens and Circle to Search can show visually similar skin conditions from a photo. It’s not a medical diagnosis, but as an app to identify skin conditions at a glance, it’s a fast starting point to learn the names of likely rashes, bites, or bumps.

How it works

Open Google Lens or use Circle to Search on a supported device, point the camera at the area (or upload a photo), and run a search. Lens returns images and results that look similar to your skin finding so you can compare and read up on common possibilities.

  • Capture or upload a clear, well‑lit photo.
  • Run the search to see visually similar conditions and related info.
  • Refine with simple terms (e.g., “itchy,” “kid,” “elbow”) for better matches.

Who it’s for

Ideal for anyone who wants quick, free triage before contacting a clinician—parents checking a child’s rash, adults puzzled by a new spot, or users who don’t know the right medical term. Use it to learn and narrow options, then decide if you need care.

Pricing and platforms

Included as a consumer feature with Google Lens and Circle to Search on supported devices. Check your device to access Lens or Circle to Search; there’s no separate subscription fee for this feature.

Limitations and privacy

Lens finds look‑alikes; it does not assess risk or provide a diagnosis. Urgent, rapidly spreading, or painful lesions warrant professional care. Because you’re submitting a photo to a search service, review your Google account and device privacy settings before use. Results depend heavily on image quality and lighting—retake photos if needed.

3. AI Dermatologist: Skin Scanner (AI-Derm)

AI Dermatologist (AI‑Derm) is a prediagnostic skin scanner that helps you monitor spots, birthmarks, moles, and rashes and decide when to seek care. If you want an app to identify skin conditions with structured guidance rather than a simple image search, AI‑Derm pairs photo capture with risk cues and tracking over time.

How it works

You photograph the area of concern and the app analyzes the image against common conditions. The App Store listing notes it recognizes 58 different skin conditions and can advise when to book an appointment. It’s built for ongoing monitoring as well as one‑off checks.

  • Capture clear, well‑lit snapshots of skin findings.
  • Answer brief prompts to add context.
  • Review look‑alike conditions and suggested next steps.
  • Track changes over time with stored photos.

Who it’s for

Useful for people keeping an eye on moles, parents monitoring recurring rashes, and anyone who wants a guided “AI dermatologist” experience to narrow possibilities before a visit.

  • Mole watchers: Log shape/size changes between checks.
  • Rash triage: Get names for likely look‑alikes to research.
  • Pre‑visit prep: Organize images and notes for your clinician.

Pricing and platforms

Available on iOS and Android. Check your app store listing for current pricing and any in‑app purchases or regional availability.

Limitations and privacy

AI‑Derm is prediagnostic and does not provide a medical diagnosis. Urgent, rapidly evolving, or painful lesions require professional care. Accuracy depends on image quality and lighting, so retake unclear photos. Because you’ll upload sensitive skin images, review the app’s permissions and privacy policy before use, and store results securely on your device or account.

4. Skinive: AI skin checker and mole risk assessment

Skinive positions itself as an AI “skin scanner” you can use 24/7 to check spots, rashes, and moles from your phone. If you want an app to identify skin conditions beyond a basic image search, Skinive aims to guide you with an AI dermatologist–style experience and help you keep tabs on changes over time.

How it works

You capture a clear, well‑lit photo and Skinive analyzes the image to surface likely look‑alike conditions and practical guidance. It’s built for quick triage and ongoing monitoring so you can learn what a spot might be and whether it’s worth a closer look later.

  • Snap a photo: Use even light and sharp focus.
  • Get AI guidance: See visually similar findings and suggestions to consider.
  • Track over time: Recheck the same area to watch for changes.

Who it’s for

Good for anyone who wants a round‑the‑clock app to identify skin conditions, especially people tracking moles or managing recurring rashes. Parents can use it for quick learning before contacting a clinician, and adults can use it to organize photos between checkups.

Pricing and platforms

Skinive promotes a “check skin online 24/7” experience and calls itself a free skin health diagnostic app. Availability, pricing, and any in‑app features can vary by region—check your device’s app store for current details.

Limitations and privacy

Skinive doesn’t provide a medical diagnosis and shouldn’t be used for emergencies or rapidly worsening symptoms. Accuracy depends on photo quality and lighting; retake unclear images for better results. Because you’re uploading sensitive skin photos, review permissions and the app’s privacy policy, and secure your account before use.

5. Rash ID: quick camera-based rash identifier

Rash ID is an AI rash identifier that uses your phone camera to quickly identify your rash or skin condition. If you want an app to identify skin conditions in seconds, its simple, camera‑first flow is designed for instant, on‑the‑spot suggestions.

How it works

You open the app, aim your camera at the affected area, and let the tool analyze what it sees. In return, you get likely look‑alike conditions so you can learn the names and consider next steps.

  • Open the app and frame the area in good, even light.
  • Capture a clear photo to see visually similar conditions.
  • Retake or refine the photo if details aren’t sharp.

Who it’s for

Rash ID suits anyone who needs quick triage before calling a clinician. It’s especially helpful when you don’t know the right medical term and want fast, plain‑language possibilities to research.

  • Parents assessing a child’s new rash.
  • Adults puzzled by sudden redness or bumps.
  • Travelers needing instant, mobile guidance.

Pricing and platforms

Rash ID is offered as a mobile app. Pricing and availability aren’t listed on the site; check your device’s app store for platform support and any regional fees.

Limitations and privacy

Rash ID suggests possibilities; it doesn’t diagnose or assess severity. Seek care for rapidly spreading, very painful, or systemic symptoms, and for infants or immunocompromised users.

  • Results depend on photo quality, lighting, and angle.
  • You’re uploading sensitive photos—review permissions and the app’s privacy policy before use.

6. SkinVision: mole and skin cancer risk checker

SkinVision is an Amsterdam‑based smartphone tool built to evaluate risk factors for skin cancer and keep track of potentially problematic moles. If you want an app to identify skin conditions with a focus on mole risk, it’s a well‑known option: it has been used in 3.5 million checks by nearly 2 million users and, through its smart algorithm coupled with dermatologists’ expertise, has helped find over 55,000 cases of skin cancer. Think of it as structured triage plus ongoing monitoring, not a diagnosis.

How it works

You photograph a mole or spot in clear, even light, and the app analyzes visual risk cues to return a risk indication along with guidance on what to consider next. It’s designed to help you prioritize which lesions deserve attention and to keep track of them over time.

  • Capture a sharp, well‑lit photo of the mole or spot.
  • Receive a risk indication with practical next‑step suggestions.
  • Save photos to monitor changes across repeat checks.

Who it’s for

Best for adults tracking moles or sun‑exposed spots who want a repeatable way to assess risk between visits. It’s also useful if you prefer data‑driven triage before booking an appointment; SkinVision works with insurers in several countries (e.g., Italy, Germany, the Czech Republic, the UK, and the Netherlands), underscoring its focus on early detection pathways.

Pricing and platforms

SkinVision is available as a smartphone app. Pricing and availability can vary by region; check your device’s app store for current platform support and any fees.

Limitations and privacy

SkinVision focuses on mole and skin cancer risk; it’s not a general rash identifier and does not provide a medical diagnosis. Seek prompt care for urgent, rapidly changing, or very concerning lesions. Results depend on image quality and lighting—retake unclear photos for better accuracy. Because you’ll upload sensitive skin images, review permissions and the app’s privacy policy, and secure your account before use. As with any app to identify skin conditions, use it as decision support—not a replacement for a clinician’s exam.

What to do next

Use these apps as smart triage—not a diagnosis. Start by getting a crisp, well‑lit photo and a quick sense of likely look‑alikes. If anything is rapidly worsening or you feel unwell, skip the app step and contact a clinician. Otherwise, use the results to decide whether to self‑care, monitor, or book an appointment.

  • Capture better photos: Even light, sharp focus, no filters; retake if blurry.
  • Cross‑check: Run your image through two tools (e.g., Lens for free, plus a guided checker) to sanity‑check results.
  • Document: Save photos and notes so you can show clear timelines at a visit.
  • If it looks like molluscum: Consider gentle, home support—Mollenol Sensitive for ages 2–7 and delicate areas, Mollenol 25ml for older kids/adults (avoid face/private parts), and hydrocolloid patches for pus‑filled bumps. Learn more in using Mollenol products for molluscum.

With a clear photo, a careful read of app guidance, and a practical next step, you’ll move from worry to a plan you can act on today.
