What it does
NearLens uses Bluetooth LE to detect smart glasses nearby. Ray-Ban Meta, Snap Spectacles, and EssilorLuxottica frames broadcast a wireless signature when they are on. NearLens reads that signal. No camera, no internet, no account required. Detection runs in the background. You get an alert. Most people have no practical way to know when someone near them is wearing recording-capable glasses. This app is a direct answer to that problem.
NearLens recognises compatible Bluetooth signals from smart glasses and provides private, on-device presence awareness on iPhone without app data collection.

I wanted to see if there's a way to detect when people are recording with these types of glasses, so a little bit ago I started working this project. I've hit a little bit of a wall though so I'm very much open to ideas!

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.
