Great app for your CD collection
Amazing how fast you can add music into database from old 78s to barcodes. Back in the day if your album had 17 tracks you would be typing in every track and hope that an album cover picture was available online to import.
All I can say is WOW.

Pretty amazing app
I don't have a big collection but I'll be pulling out my boxes and loading up on the app this weekend. I just got back into buying books semi-regularly, so I look forward to tracking it all.
A friend of mine has two or three of your apps. I saw him updating his movie collection and first learned about them. I can't believe the scale and scope of the kind of data that can be customized and stored. I signed up for the trial but I'll keep subscribing for sure.
Really amazing and clean apps. Reminds me of the old days. Keep up the great work.

Great app and customer service
I love this app. I use it to track my comics, my wish list, and track values when hunting for deals. I recently ran into an issue with my subscription and was helped quickly by Alwin to resolve the issue.
