Video Onion Skinning App

Hello everyone

I am looking for an phone app, whether for android or Apple, that allows you to:

1. Shoot live video
2. Onion skin a reference video for alignment

Does such an app exist? Dragonframe does not do video on their apps and i have tried Stop Motion Studio, which supposedly lets you import a video to use as a reference, but the program does not let you shoot videos but only pictures.

Thank you!! WordPress ...
