Holter Log
Symptom Diary & PDF Reports
$0.99 · Designed for iPad. Not verified for macOS.
Now in 49 languages. Record symptoms, activities, sleep and notes during a Holter study, then review or export a clear PDF diary to share with your care team.
Holter Log is a patient-entered diary designed to make it easier to keep clear, organized notes during a Holter monitor study.
Instead of relying on memory or writing events down on paper, you can quickly record symptoms, activities, sleep, naps and other notes as they happen.
Keep a clear record
Record the events that may be useful when reviewing your Holter study, including:
• Symptoms and the time they occurred
• Activities and everyday events
• Sleep and naps
• Notes and additional details
• Events recorded from your iPhone or Apple Watch companion
Your entries stay organized in a simple timeline so you can review what happened during the monitoring period.
Create a useful report
When your study is complete, Holter Log can create a clear PDF diary from the information you entered.
Review the report before sharing it with your doctor, clinic or care team.
Available in 49 languages
Holter Log includes 49 in-app languages, with automatic language selection and a manual language option when you want to choose a different language.
Designed for the patient
Holter Log is designed to help you record your own observations during a Holter monitoring period.
Holter Log does not connect to, read, analyze or interpret data from your Holter monitor or ECG. It does not diagnose medical conditions and is not a substitute for professional medical advice, diagnosis or treatment.
If you are experiencing symptoms that may require urgent medical attention, contact your local emergency services or an appropriate healthcare professional.
