Quick Answer: You can track moles with pictures by photographing each mole every 2–3 months using a free app like MoleMapper. Take clear, well-lit, close-up photos from the same angle each time. Then compare photos over time and look for changes in size, shape, color, or border. If something looks different, see a doctor.
Tracking moles with pictures works because skin changes happen slowly. Your eyes adjust to what they see every day, so you stop noticing small shifts. A photo from three months ago gives you an honest comparison.
Most people discover a worrying mole change only after it has been growing for a while. Regular photo tracking catches those changes earlier, when they are easiest to treat. A clinical trial of the Map My Mole app in the UK showed a 50% reduction in unnecessary hospital visits, because patients could show doctors clear photo evidence before booking an appointment [2].
The good news: you don't need special equipment. A modern smartphone camera is good enough to start tracking moles with pictures today.
The right app depends on your budget and how many moles you want to track. Here are the four most-used options in 2026:

MoleMapper is the most widely recommended free option. It was developed by Oregon Health & Science University with Apple and Sage Bionetworks. It lets you photograph, map, and measure moles, and share images directly with your healthcare provider [3].
SkinVision uses AI deep learning to give a low, moderate, or high-risk score within about one minute. It was built with input from a board of dermatologists [6].
MoleScope pairs with a physical lens attachment for your phone, giving near-dermatoscope quality images. Photos can be sent to a dermatologist through a secure platform called DermEngine [4].
Choose MoleMapper if you want a free, research-backed tool and plan to share data with your doctor.
Choose SkinVision if you want fast AI feedback and are comfortable paying per scan.
Choose MoleScope if you want professional-grade image quality and a direct line to a dermatologist.
💡 Common mistake: Downloading an app but never actually sharing the results with a doctor. These apps are tracking tools, not diagnostic tools. Always bring your photo history to your next skin check.
Good photo technique is the most important part of tracking moles with pictures. A blurry or badly lit photo is useless for comparison later.
Place a small ruler, a coin, or the app's built-in scale tool next to the mole in every photo. This is critical. Without a reference, you cannot tell if the mole grew 1mm or 3mm [1].
Take at least two photos per mole:
The location shot helps you find the same mole next time and proves it's the same spot.
A complete mole map should include every mole and skin lesion on your body. This gives you a full baseline. If a new mole appears later, you'll know it wasn't there before [1]. Most apps guide you through a full-body map when you first set up your account.
Use the app's built-in labeling system, or add a note with:
Most mole tracking apps store date-stamped photo histories automatically and include "what changed?" prompts to make comparisons easier [5].
Not every change in a mole is dangerous. But certain changes are warning signs. Doctors use the ABCDE rule to describe the changes that need attention [1] [2].
Draw an imaginary line through the middle of the mole. If the two halves don't match, that's asymmetry. Normal moles are usually round or oval and symmetrical.
Look at the edges. Are they smooth and clear, or ragged, blurry, and uneven? Irregular borders are a warning sign.
A normal mole is one shade of brown or tan. Watch for moles that develop multiple colors — dark brown, black, red, white, or blue patches within the same mole.
A mole larger than 6mm (about the size of a pencil eraser) deserves attention, especially if it wasn't that size before.
This is the most important one. Any change over time — in size, shape, color, feel, or symptoms — is worth reporting to a doctor. Evolution is exactly what photo tracking is designed to catch.
⚠️ Edge case: Some moles look "ugly" but have been stable for years. Stability matters. A mole that looks slightly irregular but has not changed in 12 months is less concerning than a mole that looked normal six months ago but has grown noticeably since.
Also watch for:
Check your moles every 2–3 months as a general rule. If you have a personal or family history of melanoma, or if you have many moles (more than 50), check monthly [1] [2].
Most mole tracking apps include reminder features so you don't forget. Set a recurring reminder in your phone calendar as a backup.
Frequency guide:
Your SituationRecommended Check FrequencyNo personal/family history, few molesEvery 3 monthsMany moles (50+) or fair skinEvery 2 monthsPersonal or family history of melanomaMonthly + annual dermatologist visitCurrently monitoring a specific moleEvery 4–6 weeks
Annual professional skin checks with a dermatologist are still important even if you track moles at home. Home tracking catches changes between visits — it doesn't replace a clinical exam.
No. AI apps cannot diagnose skin cancer. They can flag a mole as potentially higher risk, but only a trained doctor examining the mole in person — and sometimes a biopsy — can make a real diagnosis [7].
SkinVision, for example, gives a risk score (low, moderate, or high) based on AI analysis of your photo. This is useful for deciding whether to book an appointment sooner rather than later. But a "low risk" result doesn't mean a mole is definitely safe, and a "high risk" result doesn't mean you have cancer.
What AI apps are good for:
What AI apps cannot do:
💡 If an app flags a mole as high risk, book an appointment. Don't wait to see if it changes more.
If you're in the Greater Toronto Area, the Minor Surgery Center has clinics across the region where you can get a mole assessed by an expert. You can also use their mole removal cost estimator to understand what removal might cost if a mole needs to come off.
Sharing your photo history with a doctor makes appointments more productive. Instead of describing a change from memory, you can show exactly what the mole looked like six months ago versus today [1].
Here's how to do it:
Doctors consistently say that photo evidence helps them make faster, more confident decisions — especially when they're comparing a mole they haven't seen before.
Even with a good app, bad habits can make your photo history worthless. Here are the most common mistakes and how to avoid them.
Mistake 1: Inconsistent lighting
Using flash one time and natural light the next makes colors look completely different. Stick to one light source.
Mistake 2: No size reference
Without a ruler or coin in the photo, you cannot measure growth objectively. Add one every single time.
Mistake 3: Tracking only "suspicious" moles
New moles can appear anywhere. If you only track the ones that already worry you, you'll miss new growths entirely [1].
Mistake 4: Skipping check-ins
Checking every few months and then stopping for a year defeats the purpose. Use app reminders.
Mistake 5: Trusting the app over a doctor
An app that says "low risk" is not a clean bill of health. Keep your annual dermatologist appointment.
Mistake 6: Poor photo focus
A blurry photo cannot be compared to a sharp one. Always tap to focus before shooting.
Stop waiting and book an appointment right away if you notice any of the following:
You don't need to wait for your next scheduled check. If something looks wrong, get it seen. Early detection is the single biggest factor in successful skin cancer treatment.
If you're looking for a clinic near you in Ontario, The Minor Surgery Center has locations across the GTA including Mississauga, North York, Oakville, Brampton, and Markham. You can also read about what happens after mole removal if you want to understand the process before booking.
Q: Can I track moles with pictures using just my phone's regular camera app?
Yes, you can take photos with your regular camera app. But a dedicated mole tracking app organizes the photos, adds date stamps, and makes comparison much easier. A plain camera roll is hard to search and easy to lose.
Q: How close should my phone be to the mole when I take a photo?
About 2–4 inches (5–10 cm) is ideal for a close-up detail shot. Also take a wider shot from about 12 inches away to show the mole's location on your body.
Q: Is MoleMapper available on both iPhone and Android?
MoleMapper was developed with Apple and is primarily available on iOS. Check the App Store for the current version. Some Android alternatives exist, but MoleMapper's research backing makes it the most cited free option [3].
Q: What if I have a mole on my back that I can't photograph myself?
Ask a partner or family member to take the photos for you. Alternatively, some clinics offer professional mole mapping services where a trained technician photographs your entire body. You can read about mole mapping clinics in Toronto to find a nearby option.
Q: Do mole tracking apps work for dark skin tones?
Most apps work across all skin tones, but color changes can be harder to detect on darker skin. Pay extra attention to changes in texture, shape, and size — not just color — and discuss this with your dermatologist.
Q: How do I know if a mole is new or if I just never noticed it before?
This is exactly why you should document all moles from the start. If you have a baseline photo from six months ago and the mole isn't in it, it's new. Without a baseline, you're guessing.
Q: Can children use mole tracking apps?
Yes. Parents can use apps to track moles on children, especially kids with fair skin or many moles. The photo rules are the same. Bring the photo history to the child's annual skin check.
Q: What is the "ugly duckling" rule?
It means any mole that looks noticeably different from your other moles deserves attention — even if it doesn't tick every ABCDE box. Your moles tend to look similar to each other. An outlier is worth checking.
Q: Should I stop tracking once a mole is removed?
No. Keep tracking the rest of your moles. Also photograph the removal site to monitor healing. You can learn more about whether moles grow back after removal if you have concerns post-procedure.
Q: Are atypical moles more dangerous?
Atypical moles (also called dysplastic nevi) have irregular features but are not cancer. They do carry a higher risk of changing, so they need closer monitoring. Read more about atypical moles to understand what to watch for.
Tracking moles with pictures is one of the simplest things you can do for your skin health. You need a smartphone, a good app, decent lighting, and a consistent habit.
Here are your next steps:
If you notice any change that worries you, don't wait for your next scheduled check. Book an appointment. The photo evidence you've been collecting will make that conversation with your doctor faster and more useful.
Tracking moles with pictures won't replace a doctor. But it makes you a much better witness to your own skin — and that matters.
