I like how easy it was to learn, using this toolset we were able to create our first app in less than an hour! It's very simple but powerful enough so that you don't need any previous experience with code or programming languages (C/C++). There are some bugs here and there which cause errors when building apps; sometimes even after deleting all files from project folder still causing problems. But overall i think tizen studio has great potential if they will fix those minor issues. And yes its free as well :) use this software if your looking for simplicity at least give it try once. We used tizen studio mainly because we wanted something more user-friendly compared to other platforms such as android & iOS devices.
