Ballpark — the daily estimation game
The daily game that measures how overconfident you are
Ballpark — the daily estimation game launched on August 11, 2026 with 3 votes, #2,940 of 23,274 launches that month and more than 50% of that year's launches.
What it does
Five real-world questions a day. Instead of guessing a number, you drag two brackets to trap it in a range — a narrow range that hits scores big, a miss scores zero, so honest calibration is the winning strategy. Streaks, an emoji share grid, challenge-a-friend links, and stats that show whether your confidence matches reality. Free, no accounts, no tracking, works offline as an installable app. A one-time Pro unlock ($6.99 launch price) adds unlimited practice and the full archive.

I built a 2-min quiz that shows you how bad you are at estimatingApr 2026 · convexly.app · ▲20I've gotten to the point in my career where I now make strategic decisions often (hiring, firing, choosing what equipment to go with, etc.), as well as in my personal life where I need to strongly weigh my options for a big purchase or investment. I found a not-so-surprising parallel between the two as these decisions "resolved." Am I making good decisions or am I getting lucky? Did some research, read some books, and realized I should get in the habit of tracking my decision process. That quickly turned into the idea that formed Convexly. The landing page is a 10-question calibration quiz…

Clipto MCP▲655Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
