Keep an eye on your moles.
Dermo is an app that helps you keep track of moles and skin spots over time, so you can spot changes early.
How it works
Take a photo
You point the camera at the spot and mark where on the body it sits. Then you answer a few short questions about shape, colour, and whether anything has changed lately. Based on your answers, the app gives you a risk level.
Set a reminder
You decide how often you'd like to check the same spot again, whether that's every two weeks, monthly, or every three months. When the reminder fires, the app opens the camera on the right part of the body so you can take another photo of the same place.
Compare over time
Your new scan is placed alongside the previous one, and you can clearly see whether anything has changed in shape, colour, or size. The full history is yours to take to a doctor if you ever need to.
Follow the same spot over time
It's the changes over time that often say the most about a mole. Dermo places new photos next to the older ones, so you can clearly see whether a spot has grown, changed colour, or shifted in shape. When it's time to check the same place again, the app sends you a reminder so you don't have to remember on your own.
- New and old photos next to each other
- Reminders every two weeks, monthly, or quarterly
- A tidy history you can show a doctor
A simple check you can do yourself
After you've taken the photo, you answer a few short questions based on the ABCDE method dermatologists use. You're asked about shape, border, colour, size, and whether anything has changed recently. At the end you're given a clear risk level and a short note on what to do next. The check is free, and you can do it as often as you like.
- Built on the ABCDE method dermatologists use
- Risk level from low to high, in plain language
- Unlimited use, no subscription
AI analysis if you'd like one
Once you've done the regular check, you can also pay $1 to have the photo analysed by an AI. You're given a list of what the spot might be, a read on whether it looks benign or suspicious, and what to do next. You pay per analysis, not through a subscription.
- The three most likely explanations
- $1 per analysis, only when you need it
- You see what the AI noticed and how sure it is
Honest about what the app can and can't do
Dermo is a tool, not a medical device. This section explains plainly where the app is useful and where its limits are.
Not a diagnosis
Dermo helps you decide whether a spot should be looked at more closely, but it does not give a diagnosis. If you're in any doubt or worried, you should speak to your GP.
You always see why
Every result tells you what the app saw and how sure it is of its assessment. If it's uncertain, it says so clearly, so you're not left guessing what's behind the answer.
Your photos are yours
Photos are stored encrypted on servers in the EU, and you can delete your account at any time. When you do, every photo and all your data is deleted along with it.
