My husband Douglas, a high school Physics Teacher, has written several apps that are available on the iTunes Store. These apps are beneficial to both high school and college math and science students. The Cool Converter can also be used by bakers to convert temperatures. I'd love for you to share these with your friends, children, nieces, nephews or anyone that may find them to be a useful tool.
Doug and I have also worked on two Apps together. So far we have a CAS Birthday and CAS Autumn App.
I hope you'll pop over to Doug's developers page here to view all of his Apps!
