CardGate: Block apps behind a quiz
Your phone that makes you study before it opens Instagram
What it does
CardGate intercepts the apps that waste your time and puts a flashcard in front of them. Answer correctly, the app opens for a few minutes. Get it wrong, study the card and try the next one. Bring an Anki deck, sync from AnkiDroid, paste a CSV, or have the model build a deck from your notes.

I wanted to find a way to use Instagram without ending up scrolling for two hours every time I open the app to see a friend's story. Most screen time apps I found focus on blocking the app itself instead of the addictive feed, so I created this app to allow me to keep using the "healthy" and "social" features and block the infinite scrolling (Reels) After implementing the block on Instagram Reels, I got addicted to YouTube Shorts and Reddit feed. So, I extended the app to cover these as well. To avoid replacing the scrolling for regular feeds, I also added a feature that shows a pop-up when…



- IBI built FlipCards – a flashcard app with variations to improve learning2025 · flipcardsapp.vercel.app · ▲42
Hi HN, I’m Felipe, a 9-5 developer aiming to become a full-time indie hacker. I struggled with flashcard apps that focus on decorating cards instead of learning concepts, so I built FlipCards to solve that problem. What it does: FlipCards lets you: - Create cards for any concept (math, language, coding, etc.) - Add multiple variations per card – the more variations, the better your understanding - Study smarter – the algorithm randomly selects variations so you can’t just memorize Q→A patterns Why it’s different: - Most apps use reverse cards (Q→A, A→Q). FlipCards uses variations to…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
