Great App
This is a fantastic app and worth every penny! It is super-easy to use and I love the ability to randomly choose a movie from my vast collection. I have ended up watching things I didn’t even know I had. Highly recommended! Customer service is also excellent.

You guys are the best customer service in the world! I love all your apps and of course still use Books, Movies and will soon use the LP/CDs apps as soon as I have to time start adding my music to the apps!

Today is New Comic Book Day, so the perfect day to release the new NCBD feature for your trusted Add Comics screen! We bring you a completely redesign of the Pull List tab, you know, the rightmost tab of Add Comics. At the same time, we are renaming the tab to “NCBD” as we figured that this was a better fit of what the feature does, especially after today’s complete redesign.

Here’s what’s new:

  • In the Add Comics screen, the fourth tab is now called “NCDB” (previously “Pull List”)
  • Navigate over weeks with next/previous arrows, or click on the week/date for a dropdown
  • Release list now directly shows the issues, as a Card View with big images
  • Click on an issue to see all its variants
  • New: filter by “#1’s”  to show all #1 issues (so all new series)

  • Sort issue list by Popularity or Alphabetically

To try the new NCDB tool for yourself, open the Add Comics screen, then choose the 4th tab called “NBCD”!
