Track your skin, catch changes early

The single most important thing you can do to catch skin cancer early is to notice when something changes. Many melanomas don't look dangerous to begin with. They look quite ordinary at first, and gradually turn into something else. That slow change is exactly what the tracking feature in Dermo is built to catch.

How the reminders work

When you finish a scan, Dermo asks whether you'd like a reminder to check the same spot again later. You choose an interval that suits the spot itself, whether that's every two weeks for something you're watching closely, monthly for a mole you'd like a casual eye on, or every three months for a longer-term check. When the reminder fires, the app takes you straight to the camera with the body location already filled in, so you can take another photo of the same place.

See what changed, side by side

Every time you scan a spot that already has an earlier photo in the app, the two images are compared for you. You see them next to each other on the results screen, along with an updated ABCDE assessment if it's a pigmented spot. If the new assessment is stricter than the previous one, that's flagged clearly. If you've ordered an AI analysis, the AI can also comment on changes in shape and colour between the two images. This is exactly the kind of history a dermatologist can use when a decision needs to be made.

A history you can share with your doctor

If you do end up at the dermatologist's, you'll arrive with something genuinely useful: a tidy timeline of photos and assessments going back weeks or months. You can show your doctor exactly when a change started, how quickly it progressed, and what the app flagged along the way. That kind of documentation is hard to put together without an app like this.

When to set a reminder

A good rule of thumb is to set a reminder when Dermo shows a medium or high risk level, when you notice a new spot that wasn't there six months ago, or when a doctor has asked you to keep an eye on something at home. For moles you've had forever, and that have never looked any different, there's no reason to set a reminder at all. The feature is built for spots you actually want to watch, not for cataloguing every mark on your body.
