I keep an MS Excel spreadsheet on all my firearms with Model #...Serial #... Date of Manufacture... Caliber... etc...and a Range Book with each firearm to record round count and other pertinent info...especially which ammo works best ( POA/POI ) in that particular gun.
Like havasu...one copy on a thumb drive and one on the hard drive...and one in a bank safe deposit box....pictures included for insurance purposes. The one at the bank gets updated with a new thumb drive every 3 months.
Don't think I would want to keep those records on a smart phone...
I also inventory my various calibers on a MS Excel spreadsheet...( Yea...my inventory IS that large )
