Mult*Marbles Available on the App Store

Multiplication Marbles is now available on the App Store. It is free for a limited time. Thank you, Yancey Labat, once again for the marble-ous artwork. Thank you, beta testers, for the important feedback. And thank you to my daughters for being my design and feasibility focus group, my prototype marble makers, my UX team, my sound engineers, and most of all, my inspiration.
