Show HN: Engagement Experiment – Venmo vs. Cash App

I built a very small internet experiment to measure engagement between payment platforms. The idea is simple: Venmo vs Cash App. Participants can tap $1 on either platform and it counts as an engagement signal. There is: • no product • no donation • no reward • no exchange The $1 simply acts as a friction signal to measure which community shows up. The site displays live engagement data including: • platform split • time-of-day activity • engagement heatmap It's basically a real-time behavioral experiment. Curious to see which community participates more.
