Products that do what Friendly prediction markets to turn trips into a running tournament does
On a trip with my friend, he introduced me to Kalshi and Polymarket and was shocked at how degenerate it was being able to bet on literally anything. So naturally I built an app ironically where we could do the same thing (with fake money) on group outings! Managed to get a prototype finished in time for our big 14-person annual ski trip and we had a blast 'betting' on things like "Will [friend that always breaks his phone] break his phone?" and "Who will win the first game of Jackbox?" Having a low-stakes running leaderboard during our trip was so fun that I decided to flesh it out and…

I wanted to see how difficult it would be to build a web app using a sub-$300 android smartphone. Decided to build a fun predictions website where you could bet virtual (not real) money on predictions made by others, and also make predictions of your own. Building it turned out to be considerably easier and more fun than I anticipated. Primary tools used were: # QuickEdit as the mobile code editor (Note: the free version of the QuickEdit app is riddled with ads, it shows an advert each time you close a tab, but it unfortunately had the best UI of the 3 or so Android code editors I tested.…

Hi HN! Excited to show off the project we've been working on for the last couple months. We started with an idea for a crazy twist on prediction markets: You come up with a question for traders to predict, and then decide the outcome yourself. For example, you could create a market on “Will my date with [X] go well?” Anyone can bet on it, and the bets create a forecast on the chance your date goes well. After the date is over, you get to judge the result and reward the traders who picked the correct side. There are so many ways for this mechanism to go wrong: the creator of the market can be…

With my friends we wanted to have a nice friendly competition (no money involved) about the football worldcup by predicting the results. I though this might interest other groups of friends so I coded a website just for that in 3 days. Nothing ground breaking but I like the suscription system "Doodle" style with just links, no personal infos... Tell me what you think !

Hey HN - my friend and I built Prediction Hunt, a site that aggregates data from prediction markets like Kalshi, Polymarket, and PredictIt into one simple dashboard. It updates every few minutes, shows probabilities for each event, and even highlights arbitrage opportunities when markets disagree. I made it after getting tired of flipping between tabs just to see how each market was pricing the same question. Would love feedback on the product, data accuracy, and any ideas for what you'd want to see next.

So, after many years of kicking about little apps and not putting the full effort in, I decided to bite the bullet and get on with it. Very much inspired by patio11 and Bingo Card Creator, I present Griddol (http://www.griddol.com) a tool to create and play word searches. Intended mainly for teachers, but encouraging those who like a word search too. This been churning around in my head for over a year in various forms, and I used the concept to help learn CoffeeScript, CouchDB and node.js, so even if the product itself is a failure, the learning process has been valuable. I'll be the first…

Hello HN! I'm excited to share my product that helps companies to track their competitors, their website updates, new features, social media activity etc. I already have the first set of early adopters (thanks to a pretty good ProductHunt launch) who're using it on the daily basis so I'm excited to remove the waiting list and share it with everyone. Cheers!

This project grew out of frustration of trying to find out the odds of a Hantavirus pandemic. When I went to search for it, I had to wade through sports gambling, and novelty markets that distracted me from just getting a really useful number with context to know if it was accurate. To solve this, my friend and I made mondael.com, which we're using to analyze, and visualize interesting prediction markets in the realm of: Geopolitics, Elections, Macro, Finance, Energy, and Science & Technology. The basic belief is that prediction markets can often move faster than news, but only if the data…

Hey there, I've been working on a project that helps you plan a trip by swiping through attractions like tinder. Features include: - Add places by swiping - Simple to use drag-and-drop itinerary planner - Add notes to each place - Get estimated travel and arrival times between places automatically - Automatically arrange places into your itinerary (This doesn't work that well tbh) - Share trips with friends Source code available at: https://github.com/Suu-ly/Outbound It's pretty good for planning day trips but frankly not the best for multi-day trips. Let me know what you…

Hi HN, I’m excited to share something I’ve been working on: ScoutlyAI—a tool that simplifies tracking competitors’ social media and online activity. The idea came from my own frustration with how scattered and time-consuming it is to keep an eye on competitors. I wanted something that could monitor multiple sources (like websites, Instagram, and X), summarize the important updates, and present actionable insights—all in one place. ScoutlyAI does just that: • You create “scouts” for competitors by selecting sources you want to track. • It uses AI to distill changes (like posts, updates, or…
