Impressive on every level
A couple of weeks into using this and I’m increasingly blown away by the scale, stability and sheer suppleness of the app. It’s so much better than the text file/spreadsheet combo I’ve been wrestling with for the last 24 years (!)
Packed with features, a lot of which I’d never have even thought to ask for if I’m honest, CLZ Movies is ridiculously easy to use. And it’s turned what could have been tedious drudgery into something bordering on actual fun.
Seamless syncing between devices too. An easy 5 star/no notes experience

Blown away at the detail and responsiveness
WOW!
Not only was that the fastest support ticket I've gotten a response from by any company, but it was extremely detailed and worked like a charm.

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!
