I first bought a competitor app about a year ago but the developers of that app havent updated it in nearly two years, despite having a long list of suggested improvements from customers. In that time FirearmSafe has caught up with great features like last used/last cleaned date tracking, purchase date and seller info and total rounds fired tracking. I also like that this app is built for ammo tracking, something sorely lacking in some of the competition. I also really appreciate the ability to add custom categories. Dropbox export capability is also a good feature. My one and only complaint at the moment is that my gun entries do not automatically alphabatize by manufacturer nor can I make them sort. The good news is that this app is regularly improved and updated so I know I can look forward to a fix in a reasonable timeframe. You cant go wrong with this app.
