How to get idea for productive app?
I tried to build some software but it didnt work.
So can you please suggest how can I do research for idea.
Then, I'd read up on stack overflow guidelines for question asking, to improve your question.
I don't know how to help you because I don't understand what you're trying to accomplish, what you're trying to build, why you failed before, etc.
Chances are - thousands of others will say "thank you" down the road.
