Runo 2.0▲132I built Runo after years of inconsistent marathon training. GPS watches tell you your pace AFTER it's too late. So I made a simple metronome that plays a beat at your target cadence (steps per minute). New in 2.0: Apple Watch haptics (run to the beat without headphones), Strava sync, and social features. 4.7 on App Store, 10k+ runners. Would love feedback from the HN community.

Hey HN, I built Pace, a Claude Connector that lets you connect all your wearables (Garmin, Polar, Whoop, 20+) with Claude. You connect your devices once and can analyze your data with Claude. No Dashboard needed, just in natural language. I already use it everyday, especially the visualization tool in Claude makes this really cool to use. Tools include: overview, sleep, training, activity, samples and trends. Tech Stack: Python (FastMCP), Google Cloud Run, Google Cloud SQL (PostgreSQL) and Firebase It is live and free to try (no Claude Pro/MAX Plan needed).. Would love feedback,…
