I'd been using web. Photodex for a few years to make quick slideshows for clients but it was a bit too automated for me. I wanted to customize more without paying an additional hefty fee since it already costs several hundred dollars a year. Kizoa is more flexible in several areas but it's difficult to precisely edit video segments, select and time music, control music volume over video clips, etc. I've used it less than 5 times so it was a real money waster to get the lifetime membership since I've gone back to editing on my computer.
We're sorry that you don't find our app satisfactory. It's true that our video sement editing could be more precise and we definitely do have plans to improve that before summer. Regarding music control, we will indeed improve that in the future, this may take a few months before it's done.
