Stay Safe this Summer with the Wolfram Sun Exposure Reference App

August 2, 2011 —
Comments Off

It seems the sun won’t let up this summer, with many parts of the United States experiencing record-level temperatures. With the excessive heat comes the danger of overexposure to the sun, but it’s often hard to know you’re at risk until it’s too late. The newly released Wolfram Sun Exposure Reference App for iOS can aid in calculating just how much sun is too much and can offer recommendations on which SPF level to apply.

Wolfram Sun Exposure Reference App

If you are planning on spending any prolonged time out in the sun this summer, the Wolfram Sun Exposure Reference App is a great tool to have at your fingertips. By detecting your current location, the app provides personalized recommendations for SPF levels and shows you how long you can stay in the sun before you’re likely to burn.

The Wolfram Sun Exposure Reference App can also calculate the UV forecast based on your location or provide information on the UV levels for a five-day period.

The Wolfram Sun Exposure Reference App can be found on the iTunes App Store for $0.99. This is just one of many Wolfram|Alpha-powered mobile apps. More information about our other apps can be found here.

    Android sucks, seriously, get an iPhone/iPad.

      Android is superior to iOS in several ways. First, the price of any iOS-powered device (iPhone, iPad) is exorbitant compared to a comparable Android device. Second, the user base of Android is collectively much larger than the iOS user base. And finally, much of Android is open source.

…aaand I second that. Why is there no Android version?

There’s a bigger market for iOS users, sadly, so it’s no surprise that version was released first.
There will be an android version eventually.

Bigger market for iOS? Android has a collectively larger installed user base than iOS. Would also like to see Android apps from Wolfram.

I request Android version.

Also request an android version
Also, there is a bigger market for android – but it’s hard to actually tap. While the iOS market may be smaller in terms of the sheer number of users, more of the iOS users are willing to pay for the apps. I.E. you can make more money on the iOS market
Same reason why apple can get away with making their products more expensive than similar non-apple products: people are willing to pay premium for the name. Plus their hardware/hardware-software integration is really top of the line. Is that and the name worth the extra cash? That’s for you to decide

I think there should be more Wolfram Alpha Apps for Nook devices, the Nook Color and Tablet both.
