All the best for you!
When we start to develop our DecSoft App Builder at the beginning of 2015 we need to choose a good JavaScript framework for your apps, and, in that days the preferred framework was AngularJS. Powered by Google, AngularJS appears to us the best JavaScript framework to develop Single Page Apps, and therefore, that was our choice for the apps which you can create with the help of our DecSoft App Builder.
