Challenge Run

One score. One leaderboard. Real accountability.

What it does

Challenge Run is a fitness app that makes movement social and competitive. Every run generates a single score that captures how hard you worked — no pace charts, no spreadsheets, just a number your friends can understand at a glance. We're in early access and looking for runners who want to help shape tomorrow's competition platform — people who believe accountability is the best reason to lace up.

I built a frontpage for personal blogs▲783
With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
