Finally launching https://gaphunt.live on Product Hunt!
Most great startup ideas don’t come from brainstorming… they come from frustrated users.
Gaphunt helps you uncover real app opportunities hidden inside 1★ and 2★ app store reviews where users openly complain about missing features, broken experiences, and problems nobody has solved yet.
Instead of guessing what to build next, you can now discover validated problems straight from real users.**
What you can do with Gaphunt :
• Search any app or category instantly explore what users are saying about competitors.
• Surface hundreds of 1★ & 2★ reviews – the goldmine of real user pain points.
• Turn complaints into app ideas identify patterns and unmet needs.
• AI-powered market analysis understand opportunity, demand, and potential before building.
Whether you're a founder, indie hacker, product manager, or developer, Gaphunt helps you stop guessing and start building apps people are already asking for.
Would love your feedback and support on Product Hunt

Really like the angle of turning review noise into structured signals curious how you're handling the ingestion side when sources like G2 or Capterra have inconsistent rate limits. Are you running a scheduled pipeline or is it closer to real-time? The architecture there changes a lot once the dataset gets large.
Nice concept. Looking at low-rating app store reviews to find product gaps is a clever way to surface real user frustrations. It feels like a practical way to discover ideas people are already asking for. Can Gaphunt group similar complaints together to highlight the most common feature requests?
really like the idea, although more sorting options would be very helpful. Besides, some filters that target the most painful points not from big players but mid-size apps
Smart angle — mining 1-star reviews is something I've done manually for competitor analysis, but it's brutally tedious at scale. Does GapHunt currently only pull from iOS App Store, or are Google Play and web SaaS reviews (G2, Trustpilot) on the roadmap? That's where a lot of B2B pain lives.
Good and useful for problem identification and the first steps to start building a startup. I'd advise promoting the tool in pre-accelerators, startup schools and so on
As a non-dev founder, I’m perpetually worried about building the 'wrong' thing. Gaphunt sounds like exactly the reality check I need. Does it currently support all App Store categories, or is it focused on specific niches? Love the 'goldmine' analogy—super clever!
Really smart angle here. Mining bad reviews for product ideas is honestly something more founders should be doing instead of guessing what to build next.
• Love that you're pulling from 1 and 2 star reviews specifically. That's where the real pain points live.
• The AI analysis layer on top is a nice touch. Manually reading through hundreds of reviews gets old fast.
• One thought: once someone builds the app they find through GapHunt, they'll need a way to collect feedback from their own users too. Something like Blocfeed (in-app bug reporting widget) could help close that loop and keep validating with real user input.
Congrats on the launch, this is a solid tool for the ideation phase!
I think that this is a cool complementary website to PH. Also like @ProblemHunt :)
