HeartBLE for Apple Watch

What it does

HeartBLE: Skip the chest strap. Broadcast your Apple Watch heart rate directly to Mac, PC, iPad, Zwift, Rouvy, MyWhoosh and any trainer — no iPhone in the middle. The only app in the niche that uses standard HR BLE protocol for true direct connection. No intermediate phone, no battery drain. Just enable Bluetooth + Health, pair once, tap Start. Reliable throughout your workout. Built by a cyclist for indoor cyclists, rowers & runners who hate chest straps and complicated phone setups.

  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.
