Ratings and reviews

I never review apps, but this app is amazing! it's everything I could ever want and amazingly accurate - when I follow its guidance, I tan but never burn. the newest features make it even better. (one fix to request please: the orange "continue" button on the TDU goal setting screen is now underneath the android navigation bar) I'm glad the developer is keeping the app updated because I can't imagine going a summer without it! and this app is free?!

It's a useful app. It does the job well. It's annoying that the numbers all reset to defaults when you change one of them. Setting your target tdu first and then changing the spf number will then reset the tdu number. If these bugs with the input numbers could be fixed it would be a 5 star app

Has the potential to be great. I love the UV ratings based on location. I like the timer and the suggestions based on skin type and SPF covering how long to sit on each side. However, the input options bug out constantly. I can't put an SPF rating of 30 then set target each side as it is stuck at zero. UI is not very userfriendly and I also do not like the microwave sound for when the timer is up, as although it's funny, it's far too short and I've had to set phone alarms incase I missed it.
