Looks like it might work well keeps crashing

This app works fine on my iPad but it constantly crashes on my iPhone even if Im not doing anything. I have it open and not touching it and it will close on my phone. Also since it wont stay open on my iPhone I cant tell if there is a way to sync the notes between the iPad and the iPhone they appear to be different and dont sync
