The cause of iPad Air 2 freeze

I am now pretty sure that this app is the cause of my iPad Air 2 freeze after restoring my iPad several times. I have several thousand resources with Logos and whenever I load all onto my iPad Air 2, the iPad starts to freeze. The only way to revive the iPad is to delete this app or only to load a handful resources. However, if I cannot load all resources to the iPad, what is the point for me to purchase a 128Gb model in the first place? This problem has to be addressed. Before this has been resolved, I cannot give any stars though I am forced to give at least one. BTW, this is the first time I am compelled to write a review.
