Does not work anymore.

I used this for years & it worked great. I tried opening it about May 2025 as usual, “Time to sunburn”, “Compute” with the default “Skin Type:” the default of all. It shows the computed values briefly & immediately crashes.
Tried it again same year, once in June and once in July hoping that it got fixed, but it still crashes.

Now working again (09-07-2022)

I have just returned to remove my recent review saying that this usually very reliable app had suddenly stopped providing any data no matter which category I chose… As of today, Saturday July 9th, all data I request is being provided again, thank you. Here in the U.K. we are currently being exposed to very high UVI levels (8!) that I have only been exposed to when on holiday in the Mediterranean countries where very UVI levels can be expected at this time of year. I am so glad to now be able to continue using the excellent Wolfram Sun app as a tool in my sun awareness/protection toolbox! Thorvald (pronounced Tourval…)

What happened????

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

No info

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

Exactly what I needed

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+
