Holter Diary

Holter Diary is a simple, private diary companion for people wearing a Holter monitor. Record what you feel when it happens, keep entries in time order, and create a clear PDF diary to review with your doctor or clinic.

RECORD SYMPTOMS QUICKLY

Save the event time first, then add details when you are ready. You can record:

• Symptoms and heart-rate readings
• Activity and possible triggers
• Severity, duration, and notes
• Whether you pressed the Holter device button
• Electrode, wire, and other device issues

KEEP EVERYTHING IN TIME ORDER

Review symptom events, heart-rate-only readings, and device issues in one chronological timeline. Add a late entry or correct a detail when needed.

CREATE A CLEAR PDF DIARY

After the monitoring period ends, generate a structured PDF with the session summary and your recorded entries. Review the report, then choose where to save or share it.

HEALTH CONNECT — OPTIONAL

Preview recent heart-rate readings from Health Connect and save only the readings you choose to your active diary. Access is read-only and optional. The app does not write health records or start continuous background monitoring.

ADAPTIVE LAYOUTS

Wide views can show a two-column dashboard and symptom grid. Narrow views and larger text use a single column, and actions remain accessible in short views. Navigation, PDF controls and contrast in light and dark modes are clearer.

PRIVATE AND OFFLINE

• No account or sign-in
• Diary data stays in private storage on your device
• No analytics, ads, tracking, or remote crash reporting
• No publisher backend or cloud collection; optional paired-watch sync uses Google connectivity
• Optional local reminder for the expected end of a session

DESIGNED FOR CLARITY

Large controls, adjustable text size, light and dark appearance, landscape support, and clear guidance help make the app easier to use during monitoring.

IMPORTANT MEDICAL DISCLAIMER

Holter Diary is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. It is a patient diary only. The app does not read or interpret ECG data, connect to a Holter monitor, monitor you, or send entries to a healthcare provider.

Always follow the instructions from your clinic or device provider. Consult a healthcare professional for medical advice, diagnosis, or treatment. Seek urgent medical help for severe chest pain, fainting, severe breathing difficulty, stroke-like symptoms, or symptoms that feel dangerous.
