About

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!<p>Managed to get a prototype finished in time for our big 14-person annual ski trip and we had a blast &#x27;betting&#x27; on things like &quot;Will [friend that always breaks his phone] break his phone?&quot; and &quot;Who will win the first game of Jackbox?&quot; Having a low-stakes running leaderboard during our trip was so fun that I decided to flesh it out and share it with others for their trips, wacky professors, etc.<p>*How It Works*<p>1. Create a group for your trip and give your friends the group code to join.<p>2. Everyone starts with the same amount of Tokens&#x2F;Points&#x2F;Ski-bux that they can wager on each question.<p>3. Place bets on the options that you think will win - the more bets on an option, the more it costs to pick that option.<p>4. Anyone can propose when an outcome has happened and everyone gets 24 hours to dispute it.<p>5. Every share of the winning option pays out as 1 Token once the 24 hours has passed. So if you bet 2 tokens when the odds were 50%, you win 4 Tokens!<p>Please let me know what you think and what features I should add to make it even more fun for your friend groups!<p>---<p>Requires an account to use, but feel free to use this test account if you just want to peek around: (u: test@test.com - p: 11111111)<p>Also available on:<p>Android: <a href="https:&#x2F;&#x2F;play.google.com&#x2F;store&#x2F;apps&#x2F;details?id=com.bernikins.bets">https:&#x2F;&#x2F;play.google.com&#x2F;store&#x2F;apps&#x2F;details?id=com.bernikins....</a><p>iOS: <a href="https:&#x2F;&#x2F;apps.apple.com&#x2F;us&#x2F;app&#x2F;bernibets&#x2F;id6761561613">https:&#x2F;&#x2F;apps.apple.com&#x2F;us&#x2F;app&#x2F;bernibets&#x2F;id6761561613</a>

AI Score Reasoning

This is a well-executed hobby project that captures a fun social niche, but it currently lacks the characteristics of a scalable venture-backed business. The lack of a clear monetization strategy, low barriers to entry, and the 'single-use' nature of trip-based apps present significant hurdles for long-term growth.
