Frequent Freezing and closing are frustrating!

I am very disappointed with this notepad. Although many of the features are great, and were the reason I chose this notepad, frequent freezing, black screens, and complete shutdown of the app have me frustrated to the point that Im going to get a different one. Ive also lost information from this notepad, and had it switch to a different note than the one I was working on. These problems happen on my iPad and iPhone, and are most noticeable with longer notes.
