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 do not start out looking dangerous. They start out looking ordinary and then slowly become something else. That slow change is exactly what Dermo's tracking feature is built to catch.

How the reminders work

When you finish a scan, Dermo asks whether you want to set a reminder to check that same spot again later. You can pick a schedule that makes sense for the spot, whether that is every two weeks for something you are actively watching, monthly for a mole you want to keep a casual eye on, or every three months for a long-term check. When the reminder fires, the app takes you straight to the camera with the body location already filled in so you can photograph the same place again.

See what changed, side by side

Every time you scan a spot that already has a previous photo on file, Dermo compares the two images for you. You can see them next to each other on the results screen, along with a fresh ABCDE score when it is a pigmented lesion. If the new score is higher than the old one, or if the AI picks up on a change in shape or colour, you will see that called out clearly. This is exactly the kind of trend information that helps a dermatologist make a decision if you eventually bring the mole to them.

A history you can share with your doctor

If you do end up at the dermatologist's office, you will arrive with something genuinely useful: a clean timeline of photos and analyses going back weeks or months. You can show your doctor exactly when a change started, how quickly it progressed, and what the AI flagged along the way. That kind of documentation is hard to produce without an app, and it is one of the most valuable things a tracking tool can offer.

When to set a reminder

A good rule of thumb is to set a reminder whenever Dermo shows a medium or high risk level, whenever you notice a spot that was not there six months ago, and whenever a doctor has told you to keep an eye on something at home. For the moles you have had forever and that have never looked different, there is no need to set a reminder at all. The feature is designed for spots you want to watch, not for cataloguing every mark on your body.
