How a complaint becomes an opportunity

The best product ideas start in a complaint thread, a frustrated review, or a question nobody has answered well. NicheGaps reads those conversations at scale and turns them into gaps you can measure.

  1. Signal

    One complaint, in the person's own words: a 1–3★ app review, a Reddit or Hacker News post asking for something that doesn't exist yet. Each links back to where it was said.

  2. Opportunity

    Signals that describe the same unmet need, grouped together, with the products people are complaining about and what they say is missing.

  3. Score

    0–100 for demand, momentum, competition, willingness to pay, urgency and breadth, recomputed at least every hour as new signals arrive.

Questions

What is NicheGaps?
NicheGaps finds products people want but can't get. It reads complaints in app reviews, Reddit and Hacker News, groups the ones that describe the same unmet need, and scores each group as an opportunity.
Where does the data come from?
From public App Store and Google Play reviews of top-charting apps, Reddit communities and Hacker News discussions, plus a small, stricter selection of Shopify App Store merchant reviews. Every quote links back to where it was said, so you can check the evidence yourself.
How are opportunities scored?
Each opportunity gets 0–100 scores for demand (how many people, how recently), momentum, competition (how well existing products cover it), willingness to pay, urgency and breadth. The overall score weighs them together.
How often is it updated?
Sources are scanned continuously. New complaints join existing opportunities as they arrive, and scores are recomputed at least every hour.
Is it free?
Yes. Anyone can browse every opportunity with its scores and a few quotes. A free account opens 10 opportunities in full each day, a new selection every day, with the products people complain about, plus markets and the signal feed. Pro opens every opportunity, the top-ranked included, with all of its quotes and signals.
