What do you like best?
I started use Tumult Hype a few months ago, it's absolutely useful. This keyframe-based animation gives the opportunity to create simple animation (and use them into a GIF) or project more complex project for Web.
The whole interface is simple and after several days of study to become familiar with It the fun begins.
I recommend the PRO version because it has more features (Psysical Engine, for example) than the basic version. It's perfect for my business use.
What do you dislike?
As a new software, there are some little bugs that require to pay much more attention than a normal software. You can't completely trust it, a simple distraction could be fatal to your work.
I know the developers are always on work to fix them, in order to give us the best experience. I'm sure that Tumult Hype has a big potential and it will be show in the future.
What business problems are you solving with the product? What benefits have you realized?
Now I'm working on Acer's project. it's a interactive manual guide for users, to help them to explore what's new on new Acer products. Importing all jpg, svg and videos it's so easy to manage and animated them with the timelines and symbols (as on OOP programmation)
