A CalcuDoku application for the iPad

Perhaps you have visited my DailyCalcuDoku page. There, I provide interactivity with JavaScript, but all the work is done offline by a C application that runs on my server. Every day, a few minutes after midnight AEST (Australian Eastern Standard Time), the system launches the application, which uses the current date as a pseudorandom seed, and generates an HTML file with the daily CalcuDoku.

Actually, I have just realised that if you attempt to play immediately after my midnight, the program will fail. I have to fix it. It’s not nice when a program fails with no explanation. It might not seem a serious problem, but midnight here is 10 AM in Boston and 6 PM in Moscow...

Anyhow, after developing the Daily CalcuDoku software, I thought: wouldn’t it be nice to create an application for the iPad that does a similar thing? I started on 1 September, and the following snapshot gives you a taste of it:
