Managing blood pressure means tracking it consistently. But most apps either bombard you with unnecessary features or send your health data to the cloud. I built BP Diary to solve that problem: a straightforward tracker that lets you log readings, spot trends over time, and keep everything private on your device.
I created this app for myself first. I needed something fast to use right after taking a blood pressure reading—no signup, no syncing delays, just quick data entry and reliable visualizations. As I used it, I realized the core workflow could help others in similar situations: people managing hypertension, monitoring medication effects, or preparing health summaries for doctor visits.
What BP Diary Does
- Fast logging: Record systolic and diastolic pressure, pulse, measurement time, notes, and custom tags (like “after medication” or “just after waking”). The app remembers your last entry to speed up the next one.
- Your choice of guidelines: Select between the Korean Society of Hypertension (KSH) or ACC/AHA classification standards, depending on what your doctor uses. The app categorizes readings accordingly.
- Visual trends: See your data in daily, weekly, and monthly line charts. View category distribution breakdowns and instantly access average, high, and low statistics.
- Smart reminders: Set daily push notifications at multiple times (morning and evening) so you don’t miss a measurement.
- Export your data: Download readings as CSV or JSON for backup, migration to another device, or sharing with your healthcare provider.
- Appearance options: Dark mode support and bilingual interface in Korean and English.
Privacy by Design
Everything stays on your phone. Blood pressure records, tags, and reminder schedules live only in a local database on your device. Nothing goes to external servers, and I have no access to your data. There’s no login required, no account creation, no sync overhead.
No Cost, Light Ads
BP Diary is free. You’ll see standard banner ads while using it, and occasional full-screen ads during data export or restore operations—but not during everyday logging. The app won’t interrupt your tracking flow with aggressive monetization.
Who This Is For
If you’re managing high blood pressure, want to understand how lifestyle or medication changes affect your readings, or need a simple way to document trends for your doctor, this app fits the bill. It works equally well whether you’re using Korean or international hypertension guidelines. You don’t need to be tech-savvy; the interface is deliberately minimal.
A quick note: BP Diary is a logging and visualization tool, not a diagnostic or treatment app. It displays readings against standard medical guidelines for reference, but it doesn’t replace clinical judgment. Always consult your doctor about medication, lifestyle changes, or any concerns about your blood pressure.
I’ve been using BP Diary daily for months now, and I’m confident it’s ready for others to try. If you’re looking for a straightforward, private way to track your blood pressure on iOS, you can download it on the App Store today. Feedback and questions are always welcome.
