I'm having so much fun with your software!!
I am so overwhelmed and excited about this app! I have also installed your music app and will install your book app next. What a time saver!!
I was going to create all this on Excel - whew, that was a huge project before me. You saved a huge amount of time for me.
Your app is so user friendly. I just experimented and very quickly I was up and running. I'm telling everyone I know about these wonderful apps!

Week 29: Most wanted comics

In December 2024, we introduced a cool new way to add comics to your app: just scan the cover!

No more need to scan the barcode, no more need to find series by title and/or issue number… Just take a picture of the cover and the app shows you possible matches. Pick the right one and add it to your collection. Easy, fast… and.. everyone can do it, even if your knowledge of the comic world is limited.

Now, we expected this feature to be a hit, mainly for comics that do not have a barcode, or maybe for comics that have the barcode on the back cover. However, the Cover Scanner turned out to be way more popular than anticipated and by now it has grown to be the most popular feature in the app and, somewhat surprisingly, the main way for most users to add their comics, even for comics that do have a barcode.

So… it’s time for the next step. Let’s make this feature even faster and easier!
Here’s a sneak preview of two improvements that are coming up in version 10.3:

  • Easier and quicker match selection
  • New queue mode for adding in batch

By Odin’s Beard, it’s NCBD!

The return of Fantastic Four #1 is upon us! Kicking off a whole new volume of their adventures through time, space, science, and the human condition! When the Fantastic Four take on Doom, things go well until they suddenly go catastrophically wrong. They’re sent to four different eras in Earth’s history! Alone and isolated in wildly different time periods, Reed, Johnny, Ben, and Sue all have to fight to survive. Their only hope is to reach the Forever Stone: a mass of dense granite that happens to be one of the longest-lasting rocks on the planet, which has stayed both intact and accessible for most of Earth’s history!

Legends collide as the Man of Steel goes supersized for the Summer of Superman! In this all-new treasury edition, quintessential Superman writer Dan Jurgens pairs with the modern master of sequential art, Bruno Redondo, to craft a larger-than-life story of power, tragedy, action, and, above all — hope. When a vicious armada of extraterrestrial extremists launches an all-out invasion of Planet Earth, only Superman can stand in the way of total annihilation. But there’s something different about this attack — it’s deadly from both without… and within? It’s a tale so titanic we had to tell it at treasury size to celebrate the Summer of Superman in style! Featuring images and info from the brand-new Superman movie, plus a special photo variant cover!Superman Treasury 2025: Hero for All #1

Mover over, Big Bang!
