Inotia 3 for Ipad Identifying Items?

So I recently bought inotia 3 for my ipad but it wont let me identify the items (armor, weapons etc). So how do i identify the weapons and armor that i pick up? I have the identifying thing but when i place it on the piece of armor/weapon that i want to identify nothing happens. So how exactly do I identify the weapons and stuff since droping the identifer onto a weapon/armo doesnt work?

thanks
