The update Circuit Coder 1.1.1, that fixed a very critical bug for users of iOS prior to version 6. Unfortunately, it introduced an even more critical bug, occurring for everyone, that caused loading files to get corrupted (last time around it was saving files).

Luckily, version 1.1.2 that fixes this is out and I urge everyone to upgrade to it immediately. Now that we can put this tumultuous week behind us, I really hope you can give the new sandbox mode a go!

Many people have been asking for a "sandbox" mode in Circuit Coder for a long time, and it is finally here!

We have added 6 empty levels of various sizes, where you can build anything that you want, without an end goal. What makes the new sandbox mode great, however, is that you can add interactive components, like buttons and LEDs, and then run your circuit simulation in real-time.

This allows you to come up with challenges yourself, like creating a push button that will toggle a LED, but keep the signal sustained in between. Running it in real-time, while hiding away everything except the button and the LED, gives you a real sense of coding something.

Circuit Coder 1.1 was released a few days ago, but it had a critical bug that caused corrupted save files and crashing on anything earlier than iOS 6. We were able to track down the bug and push out version 1.1.1 just two days later (thanks to Apple expediting the review process, and J, who was the first to point out the bug and help me debug it).
