As of April 29th, 2015, the 1.0 version of WheelMasks is on Apple's servers waiting for review. I hope it gets reviewed soon and they don't have any objection to it.
When it's approved and ready to download I'll announce it here, on twitter and on facebook. I haven't set it to be automatically released on the App Store because I want to have a little control over when it's released, but you can be sure I won't delay it by much.
I'm very much looking forward to it.
