What it does
A free daily condition score for Apple Watch — no extra wearables, no subscriptions. HRV Flow turns your wake-up HRV, resting heart rate, and sleep into a 0-100 score every morning. Score insights tell you what changed: "Wake-up HRV was low" or "Sleep was short." Score low? Try a 1-minute breathing exercise on Watch or iPhone. Watch your heart rate drop from 82 to 68 bpm. Score → Breathe → See the change. 11 breathing patterns, recommended by time of day. All data stays on your device.

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.
