What it does
My friends and I had this low-grade anxiety we couldn't pinpoint. It was the loop. Open an app, scroll, feel worse, repeat. At dinner, at work, in bed. I built Lerf to break it. Start a session, pick what to block, put your phone down. That's it. Easy Mode lets you end early with a press and hold. Strict Mode keeps apps blocked until the timer ends. No account. No streaks. No dashboards. Nothing to check. Free on iOS. Designed to be set down.

Mom ClockJan 2026 · momclock.com · ▲742Hi HN, I’ve tried dozens of reminder and habit apps over the years. They’re all polite. Gentle. Easy to ignore. So I built something intentionally different. Mom Clock is a reminder app that behaves more like a strict parent than a productivity coach: – no snoozing – no “later” – optional app blocking using Screen Time APIs The idea came from my own behavior: I don’t need motivation — I need enforcement. This is not for everyone. Some people hate it. Some people love it. I’m genuinely curious where HN stands on this tradeoff: comfort vs. effectiveness. Happy to answer questions about: –…
ScreenBreakDec 2025 · screenbreak.app · ▲125Hi 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. There was no useful middle state. In reality, people still need to open apps like TikTok or Instagram for specific tasks: looking something up, replying to someone, checking updates, etc. The problem isn’t intentional use; it’s the unplanned, unconscious scrolling that follows. I wanted a system that interrupts the impulse without fully preventing access. ScreenBreak uses soft blocking plus…
EvoCat2025 · evocat.app · ▲17I’ve always struggled with mindless scrolling, even when I had important work to do. Timers and app blockers never stuck — they felt boring and were easy to bypass. I built EvoCat as a small side project to solve my own problem. It’s a simple iOS app that blocks distracting apps and websites, but adds a fun layer of gamification: • You earn XP for staying focused • You evolve a digital cat as your self-control grows • Each evolution makes the blocking stronger (harder to quit sessions) It’s still in early beta, but this approach has helped me stay more mindful with my phone use. Would love…
I Made the Hardest Focus App2025 · apps.apple.com · ▲43my phone secretly robbed all my dreams and i didn’t even knew it got so bad. when i saw my screen time being about 11hrs with ~95 phone pickups per day, i realized how bad it got. my problem is that i could not avoid social media entirely as i post actively because i’m involved in marketing and branding. I tried the usual, app blockers & time limits, but i always find myself hitting “one more minute” like a junkie. i’m not looking for a complete social media absence or deleting everything as these radical solutions don’t fit my lifestyle and needs and i tend to come back needing even more.…

Clipto MCP▲655Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
