# Heart Monitor 24 > 24-hour ECG recording with Polar H10.

Heart Monitor 24 connects to your Polar H10 chest strap and records continuous, high-resolution ECG data for hours or even a full day, so you can finally see what's happening between those brief snapshots.

Clinical recording equipment costs $3,000 or more. A Polar H10 costs around $100 and is available worldwide. Heart Monitor 24 turns it into a 24-hour ECG recorder you can wear during sleep, exercise, work, or rest — capturing the moments that short recordings always miss.


— SEE EVERY HEARTBEAT IN DETAIL —

Heart Monitor 24 captures the full electrical signal at 130 Hz — the highest quality available from a consumer chest sensor. You see the complete PQRST waveform of every single heartbeat, not just a heart rate number.

• 130 Hz raw ECG data — research-grade signal quality
• Continuous recording for 24 hours or more (Pro)
• Stable chest-sensor signal — reliable during movement and sleep
• Real-time waveform view as your heart beats


— UNDERSTAND YOUR HEART RHYTHM —

Your heart tells a story over hours, not seconds. Heart Monitor 24 helps you see the full picture — every regular beat, every arrhythmic heartbeat, every pause — with timestamps so you can connect rhythm changes to your daily activities.

• Full PQRST wave labeling on every heartbeat
• Early beats and pauses highlighted and timestamped
• Jump directly to any flagged moment in the recording
• R-R interval analysis shows rhythm variability over time
• Poincaré plot and HRV (RMSSD) statistics for deeper insight
• Correlate rhythm patterns with sleep, exercise, stress, and rest


— YOUR DATA, FULLY IN YOUR HANDS —

Heart Monitor 24 is built on a strict local-first privacy model. Your recordings never leave your device unless you choose to share them.

• No cloud — all data stored exclusively on your Android device
• No account required — no login, no tracking
• Export as CSV — open in Excel, MATLAB, Python, or R
• One-tap sharing — send recordings to anyone who needs to see them
• Recipients can open the data in the app or in any spreadsheet tool


— KEY FEATURES —

• Unlimited recording duration (Pro)
• Real-time ECG waveform as data streams in
• ECG paper-style viewer with zoom, pan, and wall-clock timestamps
• Show or hide individual wave labels (P, Q, R, S, T)
• Overview strip for quick navigation across long recordings
• Statistics dashboard: heart rate, R-R intervals, HRV, beat count
• Event table with every flagged moment — tap to jump to it
• Browse and manage all past recordings
• Import and export in standard open formats


— FREE vs PRO —

Free: Full access to all analysis features — recordings capped at 60 seconds.
