What it does
Tide reads sleep, HRV, training load, and wrist temperature from your Apple Watch — then recalibrates today's calorie target each morning. The first nutrition coach that adapts to how your body actually feels today, not the spreadsheet you set in January.
Tide adapts your daily calories to your sleep, HRV, and training load — automatically. Built for Apple Watch. One number, ready by 6 a.m.
Tide is the first nutrition coach that adjusts your daily targets based on your sleep, HRV, and training load automatically. you log food into a static target you set in january. but your body is different every day last night's sleep, today's hrv, last week's training. tide is the only coach that closes that loop. every morning at 6 a.m., tide pulls the same data your watch already collects, runs it through an on-device ai model that learns your body, and delivers a target you can actually trust with the reasoning right next to it. tide sits at the intersection of nutrition tracking, hrv monitoring, and ai coaching. each existing category does one of these well. tide is the first to do all…from jointide.fit

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…
