RunWindow taps you on the wrist when you drift outside the window you set — so you can run by feel, without looking at your watch. Pick a target: a heart-rate range or a pace range. Roll the two wheels with the Digital Crown, or pick a heart-rate zone in one tap, then press Start and drop your arm. THREE CUES, NOTHING ELSE • Fast taps, nonstop — speed up • Slow taps, nonstop — ease off • One tap — you're back in range The cue tells you what to do, never which number moved, and it keeps going until you're back in your window. Hold a steady effort right on the edge and RunWindow stays silent — it waits for a real drift, not a wobble. WHEN YOU DO GLANCE Color Field turns the whole screen into the signal: green in range, warming toward red when you push too hard, cooling toward deep blue when you're too easy, with the word on screen so colour is never the only cue. Prefer a gauge? Swipe up or down for a tick ring or a tuner. DURING AND AFTER THE RUN • Pause, resume, or change your window mid-run • Trend: your whole run drawn against your window • Summary: total time, time in window, heart-rate zones 1–5, distance and active calories BUILT FOR TRAINING, NOT TRACKING • Heart rate streams live from the watch during the workout • Pace comes from GPS, smoothed so a single bad fix can't buzz you • Quick heart-rate zones from your age, plus your own saved windows • Miles or kilometres • Every run is saved to Apple Health as a workout • No account, no phone app, no data leaves your watch RunWindow runs on Apple Watch only. It needs Health access for heart rate and Location access for pace. A one-minute demo shows every cue without either.
