Not a diagnosis · a photo diary for your skin
The useful question is not
“is this bad?” — it is “has it changed?”
No app can tell you whether a mole is cancer from a phone photo, and any app that claims to is lying to you. What software genuinely can do is remember: hold every spot on your body, photographed in the same way on known dates, measured against a coin, so that a real change is obvious instead of invisible.
How it works
Photograph the spot
The app checks the photo before it accepts it — focus, lighting, glare, distance. Put a €1 coin next to the mole and it can measure the actual width in millimetres.
Pin it on the body map
Rotate the model, click where the spot is. Six months later you will not remember whether it was the left or right shoulder blade. The map will.
Four models describe it
Gemini, GPT-4o, Claude and Qwen each describe the same photo independently. Where they disagree, you are told — disagreement is a reason to see a person.
Come back in three months
This is the part that matters. A single photo of a mole says very little. The same mole photographed twice, months apart, says a lot.
Ask a dermatologist
If you want a human answer, send the whole history — every photo, every date, the measurements — to a licensed dermatologist and get a written opinion back.
What you get told
Four outcomes, and every one of them is an instruction about what to do next rather than a claim about what the spot is. The wording is deliberate.
Nothing in this photo matched the features we look for. That is not the same as “this is harmless” — photos miss things. Keep it in your log and re-photograph it in about six months.
One or two features are worth watching. The useful thing now is a second photo in about three months — change over time tells you far more than any single picture.
Several features here are the kind a dermatologist should look at in person. Book an appointment in the next couple of weeks. This is not a diagnosis and most spots like this turn out to be harmless.
This has features that should be examined soon — within days, not months. Please book with a dermatologist or your GP. Again: this is a prompt to get checked, not a diagnosis.
What it cannot do
Every competitor buries this page. It is the most important one here, so it is on the front.
- A phone photo is not dermoscopy. A dermatologist looking through a dermatoscope sees pigment structures under the surface that no ordinary camera captures.
- Amelanotic (colourless) and nodular melanomas often look unremarkable in photos and are exactly the ones these tools miss.
- Skin cancer is rare in the general population, so even an accurate tool produces far more false alarms than real finds. Treat a warning as a reason to get checked, not as a result.
- Most published skin-AI performance comes from datasets that under-represent brown and black skin. Accuracy is lower on darker skin and you should weight the tool's opinion accordingly.
- Nothing here can rule anything out. A reassuring result never means a lesion is safe.
