App allows you to document every detail about all weapons owned. Also a photo of weapon. It was .99 cent I think and well worth it. Just an off property security source for sn#s and all additional details.
Like the concept, though think will stick with good old pen and paper (and photos of personal weapons posted on this forum) to document firearms.... chances of getting your phone stolen (along with every detail of every firearm you own) are way higher than chances of a notebook being stolen from home.
