After receiving valuable feedback from my dedicated focus group (my daughters, who else?), I finalized the design for Multiplication Marbles — which was completely different from its original concept. The focus group became my UX team and have tested several iterations of the app, which is now in alpha testing. Thank you so much to friends and family for giving it a go! When more of the final artwork comes in, I’ll open it up to beta testing. If you would like to be a beta tester, please contact us.
