I loved this UV app so much awhile back, but due to the removal of one key feature it's become almost useless to me...

Could you please restore the ability to see your personal burn time for FUTURE times? Rather than just limit the app to tell you your current burn time? If you did, I would happily give this app 5 stars! It's beautiful and easy to use, but that feature really made it unique and useful.

When at the beach, or when I plan to take the kids out later, I'd love to be able to check this early in the morning again to see when the danger times are (and know how long the danger-time unprotected is). It would help me plan the day ahead better, and know when to truly be better attentive, since I don't always have wifi/bars to check the app at that later hour.

Great! One suggestion.

Just what I was looking for. I wanted an app that would forecast UV throughout the day and was color-coded for intensity of UV. You can switch between their “flame” symbols and the UV number. Also switches between Fahrenheit and Celsius. Bonus that it uses my hair/eye/skin tone to tell me how quickly I will burn. I love that not only can I tell it that I am using sunscreen but also what spf it is and how water resistant it is. Then i can set a reminder for how soon it needs reapplied. One suggestion for the reminder to reapply - it uses the same reminder tone that I have set for other reminders. Therefore I have ignored the reminders. Please use a unique reminder sound or allow users to set their own reminder sound. Overall, I’m very happy with this app.

A suggestion

I love everything about this app, including the “my skin” feature. It’s my favorite. BUT, I would love for the fact to fast forward to a specific time of the day, and then have it tell me how long it would take me to burn in the sun at said time in the my skin tab, and not have to guess myself with some flames or numbers via the index. I hope that makes sense.
