Amazing App
So I haven’t rated at on of apps, but I downloaded the CLZ app to track my comic books more effectively and couldn’t believe how much functionality it offers for the price. I told my wife I expected to pay $70 or $80 a year for all of the things it can do, and I was in disbelief when I saw that it was $20 a year. I figured it was some April Fool’s Day joke or special since I downloaded it late on March 31st. Nope, that’s just the price.
Offers multiple ways to scan your books in, sorts them in just about whatever ways you could imagine sorting them, and typically gives good info/details for each book you scan. Great app that I’m loving so far.
