Hi HN! This is a trail companion web app (think AllTrails) I hacked together in a couple weeks time. I was inspired to create this project while training for an extended backpacking trip. My motivation was to create a UI tailored exactly to my liking, and to be able to track my progress along the trail without draining my battery. I also wanted to experiment with PWA technologies. I successfully used it on my five day adventure along the Knobstone Trail in southern Indiana, and even though it's web-based it hardly consumed any battery life on my old first-gen Pixel XL. It's set up currently…

- MAMBCompass – Android Compass App2025 · github.com · ▲61
Hey HN, I built MBCompass, a lightweight, privacy-friendly compass app for Android. It works fully offline, doesn’t ask for unnecessary permissions (no GPS, no internet), and is open source. Most compass apps out there are bloated or ad-heavy. I wanted something clean, fast, and featurish. So I made this! It’s only ~1.7 in size and uses a low-pass filter to smooth sensor readings. I’d love feedback or thoughts – especially from others building simple, privacy-first apps! https://f-droid.org/packages/com.mubarak.mbcompass/…

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…
