No good

Downloaded the app. Tried to use for the first time and it kept shutting down. Never got started. Not use to having it so no loss. I deleted it. 🤷🏻‍♀️

Stopped Working- App kicks me out

I liked this up first – it seemed to work well as a melanoma patient I need to be very aware of you the levels. However in the last several days I could not access my profile, could not create a new profile, and as of today –it completely fails to lunch. I have deleted and re-loaded from the App Store. I have turned off and then on my iPhone. What's up?

Has Potential

Does a very good job of analyzing your situation & need for sunscreen. Does not allow changes without deleting a profile & starting over. Greater flexibility within the app would earn it more stars.
