I submitted the fraction calculator part of iSciFiCalc a few days ago and am waiting for it to be accepted. The fraction calculator part includes a new and very clean User Interface that gets you right to multiplying, dividing, adding, and subtracting your fraction right away. I have included a video on the website of the whole calculator here. Feel free to check it out and go visit it on the app store.
Also, I have finished the basic movement of my next application, which is a game. I hope to have it finished by Christmas, not meaning being on the App Store. Check back daily for more news.
