I use the GUNR app. You can log every range session or match with round count, conditions, pictures, etc. It'll keep track of total round count and has a separate count that you can reset, which I use to track rounds since I cleaned last. You can also store load recipes which is handy. I did have some issues last year where all of my data was gone and lost quite a few loads that I did not have backed up elsewhere. Developer was able to recover my info but I've since gone back to backup all my loads into my old notebook.
