Using your smartphone to diagnose melanoma is not so smart according to a new study.
Researchers at the University of Pittsburgh studied four apps designed to analyze pictures of suspicious skin marks and provide a diagnosis.
They found 3 out of 4 of the apps incorrectly diagnosed a third of melanomas as "unconcerning."
The researchers are worried users may rely on these tools rather than seek the advice of a dermatologist.
This could lead to delayed treatment.
