Idea is nothing without execution. So, it's glad that you are determined to continue working on your idea. And, you should be happy that at least you are now working on an idea that already has its market.
If you are working on a totally new idea, it means you are trying to explore a totally new market. And, thing tends to become even worse if your web app are trying to shape new habits among people.
And, if I were you, instead of spending time working on the research, I would rather spend the time start working on the idea. You may already a prototype right now if you started working on it the last couple weeks.
But, I do not mean that research is bad. But, I will try to keep the research time as short as possible. And, I agree with aneesh, try to keep your idea as specific as possible.
Besides, I assume that you are working on your idea alone, so, it is always good to target a niche market.
