Pocket 4K to ipad mic.

I need to run the Promptsmart voice activated app on an ipad and don't want to rely on the ipads internal mics.
I will be using wireless mics and was wondering if I can just put a splitter in the Headphone out on the P4K and route the split signal to my headphones and the ipad mic input (via lighting connector).
