What it does
Riffday is an all-in-one practice companion for musicians — chromatic tuner, pro metronome, session timer, and a frictionless practice journal in one app. What's different: • 1-tap to start a session. No setup, no friction. • 3-field journal (good / improve / next). Blank saves are fine. • Heatmap & streaks make consistency visible. • 100% offline. No accounts. No servers. SQLite on-device — your data stays yours.

Cadence – A guitar theory app2025 · cadenceguitar.com · ▲195Hello HN, I just released this music theory and ear training mobile app for guitar which I've been working on for a bit more than a year on the side. The idea was to make something for the eternally "intermediate" guitarist (myself included). There are a lot of beginner apps which rely on learning songs, toolkits which give you a bunch of stuff with no explanation but not many in-between apps to actually learn and practice more generic and somewhat advanced stuff. The app contains short lessons, recaps and most importantly challenges (visual, audio and pure theory) along with a very complete…

Parallel agents, diff reviewer, and multi-model comparisons
Dev tools · May 2026 · kilo.ai
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…
