SleepCycler
8 hours of sleep, still exhausted? You're waking mid-cycle
What it does
Most sleep calculators just spit out times with no explanation. SleepCycler shows you exactly why each bedtime works — based on 90-minute sleep cycles, your age group, and a 15-minute fall-asleep buffer. Features: bidirectional calculator (wake time or bedtime), Sleep Now button, Sleep Debt Calculator with 7-night tracking and recovery plan, and a full sleep science blog. Free, no signup, no ads.

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.
