Goed en snel

“De software is erg snel en vindt de correcte boeken vrijwel direct op het moment dat de bar code gescand wordt. Zelfs Donald Duck pockets worden gevonden. Het kost een paar centen maar het werkt wel beter en vele malen sneller dan andere vergelijkbare apps die ik snel getest heb.” — Myrdano

“I've been look for an iOS app for some time to keep a library of the books I've read, so when I'm in a store I can scan the database to see if I've already read it. Very frustrating to get home and find out I already have a copy. CZL solves that issue. The bar scanner is really fast and adding my whole library was done in 30 mins.” — Riverdoctor
Terrific

Love this APP!

“We have found this program to be so helpful to catalog our book collection. The app is a great addition to the software. I am able to add books when I am away from my computer and sync it when I am able. It also helps me to keep from buying a book I already own when I'm out book buying. This has saved me money. The other thing I have used it for is to check where in my home library a book is supposed to be when we can't find it. The pictures are so helpful. I can enter the books on the software the way they are positioned on our shelves and then scroll through the pictures on the app on my iPad to see what shelf the book we're looking for is and what books it is in between. This has saved us so much time.” — HeritageCA
