ToBeat: ECG Decoder

Review Apple Health ECG waveforms with nine on-device values: R-R, RMSSD, SDNN, PR, QRS, PD, QT, QRSa, and QTc. No diagnosis or treatment advice.

ToBeat is an organizer and personal archive for Apple Health ECG records.

With your explicit permission, ToBeat uses read-only access to the Apple Health ECG records you choose to share. It displays the original waveform and stored record fields, and calculates a limited set of numerical reference values from the single-lead waveform on your device.

KEY FEATURES

• Browse Apple Health ECG records by date and time. • Filter by the Apple Watch classification already stored in Apple Health, and save favorites locally. • Swipe through the complete original waveform without beat abnormality markers. • View recorded time, source device, sampling rate, Apple Watch classification, and Apple Watch average heart rate. • Calculate nine on-device values: R-R, RMSSD, SDNN, PR, QRS, PD, QT, QRSa, and QTc. The selected HRV value and actual QTc formula are identified. • Export a PDF containing the waveform, stored fields, and these numerical values for personal archiving.

ABOUT THE VALUES

ToBeat calculates these values on device from the Apple Health record and its single-lead waveform. Raw waveforms are not sent to ToBeat servers for analysis. The exact pipeline accepts 10–30 complete seconds at 250–1000 Hz and uses the full input at its original sampling rate without resampling or truncation. R-R uses the Apple Health average heart rate; the waveform values use the original waveform. If the complete nine-value set cannot be produced, the app shows it as unavailable instead of filling in an estimate.

ToBeat displays numbers and the calculation method only. It does not provide normal/abnormal determinations, risk scores, disease screening, medical diagnoses, treatment or medication advice, or emergency services. Apple Watch classification and average heart rate are clearly attributed and displayed as stored in Apple Health.
