Apple just approved Version 2.0 of my Barricade iPhone App!

It should show up in your updates in the App Store on the phone sometime within the next 24 Hours.

I added the ability to change the number of Half-value layers and added Selenium 75 as an isotope selection.

Be sure to watch the App Store for the update.

X-Ray Timer will be updated soon to add Selenium 75 as an isotope.

I hope to develop web app version of them for other smart phones. I may switch all future development to web apps to make it faster and easier to develop.
