Holter Log
Utilities
$0.99 · Designed for iPad. Not verified for macOS.
A digital replacement for a paper Holter diary. Log events from iPhone or Apple Watch, then preview, share, and print clean PDF reports.
Holter Log helps you keep a clear, fast event diary during a Holter monitor study.
Log important events from your iPhone or Apple Watch in seconds, then review them by day or study week so they’re easier to compare with the monitor data later. Instead of trying to remember symptoms, activities, drinks, sleep times, or bathroom events after the fact, you can record them the moment they happen.
Holter Log is built to be simple when you need it most:
• Quick-log symptoms, activity, drinks, sleep, and bathroom events
• Use Apple Watch for faster event logging on the go
• Add custom “Other” entries when the preset options aren’t enough
• Edit or delete entries anytime on iPhone
• Review your timeline for today at a glance
• Group history into 7-day study weeks based on your study start
• Select specific days from a study week for review
• Export, share, copy, and print selected logs for handoff
Helpful for:
• Daily symptom tracking during a Holter study
• Matching your diary to heart monitor recordings
• Preparing a cleaner handoff for a clinic or cardiology visit
• Keeping a personal record of what happened and when
Holter Log is designed as a quick companion log for ambulatory heart monitoring studies. It does not read your monitor data or provide medical advice.
