What is Reddit's opinion of Coin Collection?

From 3.5 billion Reddit comments

I started with the Coin Collection app, which was actually pretty good! I wanted more flexibility though, and ended up creating my own spreadsheets in Google Sheets. Took a lot of effort, but was totally worth it in the end.

It's for tracking most us coins. It's pretty cool. https://play.google.com/store/apps/details?id=com.spencerpages
