v4.8: Automatic CLZ Cloud syncing!

December 6th, 2017

A new v4.8 update for your app is available now, with:

Automatic CLZ Cloud syncing
Add or edit books and your changes will auto-upload to the CLZ Cloud instantly.
Made changes on the desktop or Connect side? Just start the app and changes will download automatically.

Note: Auto-Syncing is switched OFF by default. Switch it ON in the “Sync with CLZ Cloud” screen.

Don’t have a CLZ Cloud account yet?
If you don’t have a CLZ Cloud account yet, I strongly recommend signup up for one from the app. Using the CLZ Cloud is completely free!

The CLZ Cloud syncing will let you:

  1. Sync your data between devices, e.g. between your phone and your tablet. Or from your old phone to your new phone.
  2. View your database online using the free CLZ Cloud viewer website.
  3. Make an online backup of your data. Better safe than sorry!

v4.5.7: Further improvements to the Add Books screen

November 22nd, 2017

In today’s update for the CLZ Books app, we have made further tweaks to the Add Books from CLZ Core screen, to make it clearer than previous versions:

  • Slightly smaller font for the book title, so that longer titles fit better.
  • Color high-lighting: Books already ‘on wish list’ now have an orange title, books already “in collection” show up with a blue title.

Fixes in this update:

  • After changing the sort order the list could sometimes scroll to a random position.
  • Small CLZ Cloud Sync tweaks.
  • After restarting the app it would sometimes repeatedly scroll to the last added book.
  • After manually typing a barcode in the add by barcode screen you weren’t able to search another one.

v4.3.9: Easily add books that come up as “Unrecognized ISBN”

January 18th, 2017

An important v4.3.9 update for your CLZ Books Android app is now available.

This update introduces an easier way to deal with “Unrecognized ISBNs”.
A new screen that not only helps you to add the book to your database anyway, but also helps your fellow CLZ Books users by instantly adding the missing ISBN to the CLZ Core central online book database.

(this feature was introduced for our Windows, Mac and iOS versions earlier, and in the meantime, people have used this new tool to add over 22 thousand new books to our Core!)

  • In the Add screen, when a scanned ISBN is not recognized, a new “Unrecognized ISBN” screen will appear.
  • In this screen, just enter the Author, Title, Publisher and Year, then click Add Book.
  • This will:
    1. Add the book to your own database, with the information you filled in.
    2. Add the book to our Core central online book database.

The result: for the next user who searches for this particular ISBN, it will be recognized 🙂
