Sure, maybe the better way to phrase the question is: How is OP evaluating if there is actually a large enough paying market for this product to make a business out of it? Evernote showed there was not enough of a market for it to justify increased investment, so OP either needs to identity that there is more of a market for their version of productivity app or they need to have realistic expectations about operating a niche business (if enough of a market for such a business exists for this at all).
It's not meant to be harsh, rather just realistic, productivity apps are a dime a dozen (there's literally hundreds of submissions like this over the years on HN). OP needs to know what makes their submission different.
