ZoneView: Heart Rate Zones

ZoneView turns your Apple Watch into a heart-rate-zone training companion. One glance gives you what matters mid-workout: your current zone (as color), your heart rate, and elapsed time — on the Watch, mirrored live on your iPhone, and on the Lock Screen and Dynamic Island. TRAIN BY ZONE • Live zone color, heart rate, elapsed time, and time-in-zone bar • Gentle wrist taps when you cross a zone boundary • Zones estimated from your age, or set fully custom boundaries OUTDOORS • GPS route recording for outdoor walks and runs • Zone-colored route map, distance, pace, and per-split breakdowns AFTER THE WORKOUT • History and trends: weekly zone minutes, training load, streaks, and personal records • Home Screen and Lock Screen widgets for weekly progress • Export your history as CSV, or share a workout summary card PRIVATE BY DESIGN • No accounts, no ads, no analytics — ZoneView makes no network connections • Your data lives in Apple Health and on your devices, nowhere else Requires a paired Apple Watch (watchOS 10+). ZoneView is not a medical device.
