Keeping track of your collection

[mrbubbles]

How do you keep track of collection progress?

Hey All, Curious how each person here keeps track of their collection progress/goals. I have been searching for an app that shows me all setlists and promo cards, both English and Japanese, so you can visually see what you own and what you are missing. I have experimented with a few apps but they all end up missing something in the end. Do people on here use apps or do you build your own lists? Open to hearing what everyone does.

Hopefully this can give you more insight.

Cheers!
