Wolfram Sun Exposure Reference App

Really upset lately says no data available!!! I have used this app for years and now I have no information HELP!!!

I just payed for this app for it to say there “is no data available” super lame

This is an amazing little app, especially for the price I payed. I don’t like to spend crazy amounts of time in the heat, but I also enjoy having a tan. I use this to figure out when is the best time to go out, get some quick sun and go back in. It’s also great for those who those who want to avoid too much sun exposure. Ps. Always remember to wear SPF 15+

The info provided by the app is priceless. The app would be truly great if it could remember the info I have to re-input every time u use it...

I love this app, but it's broken! Please help Wolfram!

It takes considerable talent to make an app this bad. You enter in data, from pull down lists, press compute, and the app says it doesn't understand your input - the same input it gave you! Useless.

Data can be stored by app for short term recall (up to week), the sunrise/sunset prediction is good for months. Graphics barely used, so can't read info at a glance. Detail of info is excellent, but ease of usability is very, very low.

i dislike the sun. this app helps me avoid it. really though, this little gem of an app is simple, thorough, and quite detailed in its calculations. i solidly recommend it to anyone looking to avoid skin cancer or burning flesh. no one likes burning flesh.

I like the info & useful advice on SPF. It does, however, lag quite heavily when you input info. Also, it would be useful to have your info saved as a default for skin type, day in advance, ect.

This app is one pretty *cool* collection of essential utilities, some of which I do not have already ... not only can I now compute how safe it is to work outside, but to get the current weather in a mathematic app is really *Cool* plus gaining the expertise to see the sun-earth-moon configuration is breathtaking. Seriously, this is one of many apps from Wolfram that I have on my iPad and access almost daily. When the school year returns, access will then become daily.
