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.

As simple as possible

Does what I need, which is to give me and idea of when it is or is not good to be outside. I don’t mind that’s it’s just a forecast rather than live reading. The only gripe I have is that the widget does not work great - sometimes it doesn’t update properly. (I had the android version which I think worked slightly better.)

Love the app!!

Could you maybe add an alarm when the UV drops to the safe/moderate levels? That would be so cool to get an alert when it is safe to go play outside!

Thanks again
