iWant is currently the work of Rudrajit Samanta. I am located in the bay-area and have a day job building software for an animation studio. Right now, it's just me doing the design, coding, testing and this website (in my spare time). We'll see how things go and maybe get some more people involved.
I'm trying hard to balance the simplicity of the app with it's usefulness. So I'm trying to think of other service categories to add without overcrowding the main screen. If you have any thoughts on that, feel free to write to me (see the support section).
The data shown in the app comes from various web APIs. If you'd like me to incorporate data from your service, and have a REST API for acccess, do let me know.
