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 one of the best ways 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!

App crashes

The app keeps crashing when I try to open my pictures! Having a severely atypical mole excised in two weeks - would be nice to compare to old data.

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.
