Your heart rate, always in sight
PulseGuard floats your live BPM in a Picture-in-Picture window over FitStars, YouTube or any other workout app — with color-coded zones and instant alerts when you cross the line.
iPhone, iPad, Apple Watch and Android
See it in action
Real workouts. Real heart rate. Right where you're already looking.
Why PulseGuard
Everything you need to keep your heart rate where it should be — without staring at a watch face.
Picture-in-Picture
A small color-coded square stays visible over your workout app. Your eye catches it without breaking focus.
Color-coded zones
Recovery (blue), aerobic (green), threshold (orange), max (red). Background color changes the moment your zone changes.
Instant threshold alerts
Sound, haptic on iPhone/iPad, wrist tap on Apple Watch — fired on the first sample above your limit, then every few seconds while you're still over.
Works with what you have
Standard BLE Heart Rate Profile: chest straps (Polar H10, Garmin HRM-Pro, Wahoo TICKR), armbands (Polar Verity Sense, OH1, CooSpo), watches in Broadcast HR mode, plus Apple Watch as a live source.
Zones the way you train
Tanaka, Fox, Karvonen (heart-rate reserve) or manual HRmax. Imperial or metric units. Profile imported from Apple Health in one tap.
Your data stays on device
No accounts, no analytics, no telemetry. Heart rate is read locally over Bluetooth and never leaves your device.
