Doodlecast Pro is a memory-intensive app. We have tested the app extensively on all generations of iPad and iPad Mini running iOS version 6.0 and above. But if you run into crashes we would like to know. Please use our contact form and send us the following details and any actions that lead to the crash, whether you still get crashes after restarting the device. Crashes make us sad, then angry, then sad and then we push out an update.
