Pulse - Heart Stats

Your heart rate, beautifully summarized. See min, max, and average BPM right from your widget or Apple Watch face — processed privately, on-device.

Pulse turns the heart rate data already in Apple Health into something you can actually use. Instead of opening the Health app and scrolling through raw readings, Pulse shows your minimum, maximum, and average BPM across four time windows — right where you already look: your iPhone Home Screen widget and your Apple Watch face.

KEY FEATURES • Four time windows in-app — last 1 hour, last 12 hours, today, and the current month. The full set is available inside the iPhone and Apple Watch apps; widgets and complications cover the three rolling windows (last hour, last 12 hours, today). • iOS Home Screen widgets — fifteen widgets in total: nine small "single stat" widgets (one per combination of window and metric), three medium chart widgets with min/avg/max and a workout-shaded chart, and three small arc-gauge widgets. Add as many as you like and pin the views that matter most. • Apple Watch complications — circular arc-gauge complications for watch faces with circular slots (Modular, Infograph, Modular Compact, and others), and rectangular chart complications for the watchOS Smart Stack and rectangular watch face slots. Three time windows per family — pick the one you want by adding the matching complication. • Standalone watchOS app — view all four time-window statistics on your wrist, even when your iPhone isn't nearby. Includes a chart and min/avg/max for each window. • Workout correlation — when heart rate readings overlap a recorded workout, Pulse highlights those samples in the chart with a distinct color and a workout icon, so you immediately know whether a spike was exercise-driven. • Automatic refresh — widgets and complications refresh on a 15-minute WidgetKit timeline schedule that's gentle on battery. The in-app view re-queries HealthKit when you open or pull-to-refresh. • Light, Dark, and System appearance — pick your preferred theme in Settings.

PRIVACY FIRST Pulse is built on a single rule: your health data never leaves your device. There is no account, no sign-in, no cloud sync, no analytics SDK, and no server. Pulse reads heart rate and workout data directly from Apple HealthKit, computes statistics locally, and stores them in a private App Group container shared only between Pulse and its own widget and watch extensions. Our App Store Privacy nutrition label is "Data Not Collected" — and we mean it. You stay in control. You can grant or revoke HealthKit access at any time from Settings, and Pulse will gracefully show "--" placeholders instead of stale numbers when access is revoked.

DESIGNED FOR APPLE PLATFORMS Pulse is a native iOS and watchOS app written in Swift, built specifically for the latest Apple platforms. It uses WidgetKit for Home Screen widgets and watchOS complications, supports Dynamic Type for readable text at any size, and meets Apple's accessibility tap-target guidelines.

REQUIREMENTS • iPhone running iOS 17 or later • Apple Watch running watchOS 10 or later (optional — the iPhone app and widgets work without a paired watch) • Apple Health permission for Heart Rate and Workouts (read only)
