There is new iPhone, iPod, iPad app called MiGuns. The app lets the user build a database of their gun collection. You can include all the information such as: Company, Model, Caliber, Finish Serial Number and much more. What's nice is you include a photo of your gun. The app has very strong security features to protect all the information that is loaded (no pun intended). Many police officers that have used the app said "they wish that people whose homes were robbed could supply them with this much detail in regard to the weapons that were stolen.
