### 1/5 — Very Dangerous

*2015-07-01*

This is. Highly dangerous App that could cause serious issues with regard to cancer. If the App does not receive a signal of the UV levels in your area it posts a totally safe message that may encourage people to stay out in dangerous levels of sunshine.
When I sent a message to LionApps about this the response was they post data from their data provider ( wunderunderground) and do not feel it their responsibility if that data is wrong - apparently they do not care if no data causes their App to give dangerous advice. Wunderunderground have confirmed to me by e-mail that the necessary data is not available in the UK. We hence have an App provider more interested in taking money from punters than ensuring they are giving safe and good advice.
I will be suggesting to Apple they look carefully at this provider, at least in the UK, and I will be asking for a refund
I would have prefers to give this unsafe App 0 stars but that option is not available

### 5/5 — Very accurate!

*2026-04-07*

There are lots of apps out there they do the same thing as this, but the UI is very simple and this is as accurate as any other that I have found. Five out of five!
