Show HN: Prediction market analysis app layering LLMs with data APIs

[noplace1ikegone]

I created a prediction market analysis app after trying prediction markets and doing quite poorly. I wondered if AI-driven predictions could be better with the right data. Depending on the model you use the answer swings wildly between definitely not and yes. Gemini 3 Flash and Sonnet have done well with complex pipeline analysis instructions. Examples of some data apis are FRED, the NWS, Open-Meteo, CoinGecko, congress.gov. I also incorporated general search queries with Serper and Tavily.

In full disclosure, I got maybe too ambitious and prepped it as an iOS product with monetization features. I am a vibe coder from a non-technical background and this is the first thing I created, so I would love critical feedback.

Congrats on shipping — that's the hardest step. Quick question on App Review: prediction markets feel gambling-adjacent so I'd expect specific friction. Did you frame it as an analysis tool to get through, or was Apple OK with the prediction angle directly? I just went through App Review for an iOS app in the health-info space and they were very particular about how everything was worded, so curious if your domain had similar pushback.

Did the review turn out ok? I was fortunate and didn’t end up running into any review issues, but I had advance warning. I planned the in-app copy around avoiding gambling terminology or making specific purchase recommendations.

the first thing you made - as a non-engineer - is a monetized gambling app? ok. I see no issues with this.

Good idea, your app is working well, good luck bro
