What it does
You track your steps. Your heart rate. Your calories. But what about your brain? Tacet gives you a daily cognitive fitness score and sleep quality tracking, drawn from the rhythm of how you tap your phone. Those timing patterns carry a surprisingly accurate signal about your cognitive state. No headset, no expensive hardware, no setup. Passive tracking, built on neuroscience research from Leiden University. Traditional brain monitoring is expensive. Tacet brings it to your pocket. Start today!
Most people have no idea how their brain is performing day to day. Not because the data doesn

MoodJun 2026 · mood.lasagna.pizza · ▲97Hey HN, I've had this idea stuck in my head ever since I published Year in Pixels [1].

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…
