Gun Logger tracks four metrics to help you get a feel of how reliable your guns would be in a sport shooting competition: total number of rounds, total number of malfunction free rounds, number of rounds since you changed your gun springs, number of rounds since you thoroughly cleaned your guns.
Whenever you take your guns to the range use Gun Logger to log the number of rounds that you fire. If you experience a gun malfunction you can document it with a photo and text incase the malfunction reoccurs and you need to show it to your gunsmith. When you change your gun springs or thoroughly clean your guns use Gun Logger to document that as well with the press of a single button in the app.
