PulseScan - Heart Rate Monitor

PulseScan turns your smartphone into a personal heart rate tracker. Using advanced PPG (Photoplethysmography) technology, the app analyzes subtle blood flow changes through your fingertip to deliver BPM readings — no wearable needed.

• 4th-order IIR Butterworth band-pass filter (40–240 BPM range)
• Real-time 30fps camera frame analysis
• Confidence scoring for every measurement
• Adaptive noise filtering for consistent accuracy

★ PERSONALIZED HEART RATE ZONES
• Customized zones based on your age and biological sex
• Male: Fox formula (220 − age) / Female: Gulati formula (206 − 0.88 × age)
• Four zones: Resting, Fat Burn, Cardio, Peak
• Karvonen method for precise zone boundaries

★ SMART HISTORY & STATISTICS
• Track every measurement with timestamp and zone
• BPM trend chart with cubic bezier smoothing
