Support was awesome when I emailed about possible bundle deals for both apps and they directed me right to the exact spot to bundle the two and others if wanted. I would suggest this app for anyone looking for a good catalog app.
That alone is worth it. LOVE IT!!!!

These top-10s are created by you all, the users of the CLZ app and software, as they’re based on how often these comics already appear on your wish lists in the CLZ Cloud, even before release!
Fixed:
- Keyboard would sometimes disappear after typing one letter in the search box above the series folders
- A crash when tapping a comic in the [NONE] folder
- The “downloading images” bar would sometimes show even if no images were downloading
- Comic details could sometimes fall under the bottom bar
Fixed:
- Converting/Optimizing Database process was slow/crashing for some users. We have now fixed this and made the database conversion much faster
- Sync with CLZ Cloud: The progress bar for images didn’t count the images that had to be downloaded correctly
A little bit of fun news today: We were thrilled to hear CLZ Movies mentioned by actor and playwright Tracy Letts on the latest episode of Blank Check with Griffin & David called The Year of Living Dangerously with Tracy Letts.
Tracy talks about owning movies on disc, so it’s especially nice to hear that he uses CLZ Movies to keep his collection neatly organized!

Final issue…Power Rangers Prime #16. Rangers vs the Legion Ravager. Going to be the last PR we get for a little bit, they’ll be back in May though!
Cover Girl, Jinx, and Dawn are running out of time to complete a deadly mission. Let’s see what the Blue Ninja’s have in store for them in: G.I. Joe: A Real American Hero #327C. I’ll definitely be picking up the Steve Beach variant.
DC’s. newest Next Level title has arrived: The Fury of Firestorm #1. Firestorm has turned buildings to sand and people to glass with no remorse and no warning. But what exactly provoked Ronnie Raymond to commit this heinous act, and can anyone contain the fury that is Firestorm?

No new features here, but an important improvement to an existing one: the CLZ Cloud syncing. Our mobile developers Pim and Bernard have implemented three changes that will make the down-syncing of new items from the CLZ Cloud to your app a LOT faster!
- The syncing now down-syncs the *data* first, while queuing the *image* downloads. This will make the data sync super fast.
- Downloading the images is much quicker too, especially on fast connections, as it downloads multiple images at the same time.
- As soon as the data download has completed, you can close the Sync screen and start using the app. The image downloads will continue at the bottom of the main screen, prioritising images that are “in view”.
The improvement in speed will be most noticeable when re-downloading your complete CLZ Cloud database, e.g.
- After installing the app on a new device
- After removing and re-installing the app
- After Clearing the Database
However, even during normal use, e.g. when syncing between devices, or between the app and the CLZ Web software, you will find the down-syncing to be much faster than before.
