LocknLearn - Focus & Study

What it does

LocknLearn doesn’t fight distraction - it uses it. Instead of quitting social media, you learn before you scroll. Each time you open apps like TikTok or Instagram, you answer a quick question, turning habit into passive learning through spaced repetition. You can create your own sets from PDFs, images, or text, and share them with others. It’s a simple way to remember more without needing extra study time.

LocknLearn helps you reclaim your time by locking social apps until you complete a quick learning session.

  ScreenBreakDec 2025 · screenbreak.app · ▲125

  Hi HN, I built ScreenBreak after realizing that most app blockers failed in practice. “Hard blocks” were too rigid — I either locked myself out entirely or tapped Ignore Limit and kept scrolling.

  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.
