MoleMapper™ is a personalized tool to help you map, measure, and monitor the moles on your skin. Using a familiar Maps-like interface, you can measure the size of a mole using the camera and a reference coin.

If you are 18 or older, MoleMapper™ also gives you the option to participate in a research study developed in partnership with researchers at Oregon Health & Science University to better understand skin biology and melanoma risks.

Keeping track of the size, shape and color of your moles is the best way to catch potential skin cancers like melanoma in their early stages. Whether you use MoleMapper™ to keep track of a single suspicious mole over time or construct a full-body map, we hope this app will make being vigilant about your health a bit more enjoyable.

Happy Mapping!

What's New

Version 3.1.0

* We fixed display problems with iPhone X.
* Tutorial videos have been re-done (slowed down, text descriptions added).
* We revamped the mole measurement and re-measurement process to simplify it. You can fix mole and coin sizes directly on the same screen now without transitioning to a "Fix" screen. Please note that adding mole locations is now done using a long-press gesture!
* We added a picture-in-picture feature with automatic magnification to help you see if your photos are sufficiently in focus.
* You can now turn off the help screens between measuring steps.

Research for the masses

Quantified Selfer

I am really excited that I can use a research kit app for myself and help research at the same time. I haven't seen the bugs the other users mention. I already used the app because I thought I'd gotten a new mole and was able to check my pictures (thankfully, I had not). Great app, extremely useful in the year long gap between my dermatology visits.

Not quite there yet


This app should not have been released yet. To many bugs. Keeps kicking back to the beginning when attempting to sign up. The tutorial keeps jumping back to instructions already given. To frustrating to continue. I have it one extra star because the bugs can be fixed and this could be a great app.

Nice app

Mr. Schnoidman

I like that I can look at the percent change in my mole size, pretty easy to use too.
