ThinkLeft
Know when your brain is sharp. Track fatigue.
What it does
Every decision drains mental energy — but most people have no idea when their brain is actually running on fumes. ThinkLeft gives you a real-time 0–100 cognitive fatigue score based on 4 signals: decisions made, time of day, fidgeting, and app hopping. After a few days it calibrates to YOUR baseline — so you see your personal peak hours and afternoon slump, not a generic average. Free. iPhone only.

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.
