Hello Hubski, we've been working since February to make an app. It took way longer than expected (partly because we kept adding features), but it's finally released.
This is a mobile version of our A-Puzzle-A-Day calendar puzzle, which has been doing very well. We've been contacted several times by people wanting to program an app for us but weren't impressed, until we heard from a 17-year old programmer in the Netherlands who seemed like a great guy and had written a app that looked good. We decided to give him a chance, and it was a good choice. He solved some tough problems, my wife and I did the design work, and I made all of the art. We've got something we're really happy with.
How it works: Try to place the 8 pieces in the calendar frame to leave just today's date showing. Every date is possible with the same 8 pieces. In the app you can score for up to 3 solutions a day and win DragonCoins. Use the coins to buy custom pieces (31 different themed set), hint tickets or time machine passes. There's a solution bank and a lot of cool features -- don't be afraid to click all the buttons and explore!

We hope you'll give it a try, and would love to hear feedback. If you like it, please share it around.
