Keeping a consistent blood pressure log sounds simple, but most people either forget to do it or end up with a scattered mess of notes on their phone. BP Diary is a focused Android app that makes daily logging fast, keeps your data entirely on your device, and gives you clear visual trends to bring to your next doctor’s appointment.
I built this because I wanted something in between a generic notes app and a bloated health platform that demands an account and uploads everything to a cloud I don’t control. Blood pressure data is personal, and I didn’t see a reason for it to leave the device. So I made BP Diary as a straightforward, local-first diary that stays out of the way during your day but gives you useful summaries when you need them.
What it does
- Fast, structured logging — record systolic, diastolic, pulse, timestamp, and notes in a few taps. Custom tags like “after medication” or “morning” add context without slowing you down, and the app remembers your last entry to speed up the next one.
- Multiple classification standards — choose between KSH (Korean Society of Hypertension) or ACC/AHA (US) guidelines so the categories shown match what your own doctor actually uses.
- Trend charts and statistics — line charts broken down by day, week, and month, plus category distribution and average, high, and low summaries, all at a glance.
- Scheduled reminders — set push notifications for multiple morning or evening slots so logging becomes a habit rather than an afterthought.
- CSV and JSON export — back up your records, move them to a new device, or hand them directly to a healthcare provider in a format they can actually open.
The app supports both Korean and English, and it ships with a dark mode. Everything — readings, tags, reminder schedules — lives in a local database on your phone. There is no sign-up, no login, and no server receiving your data. The developer (me) has zero access to your records.
BP Diary is a good fit for anyone who monitors their blood pressure regularly — whether you’ve been prescribed medication and want to track how it’s affecting your numbers, you’re managing hypertension under a doctor’s care, or you’re simply health-conscious and want a running record you can point to. The dual classification standard support makes it particularly useful if you’re in Korea or working with a Korean cardiologist, though the ACC/AHA option means it works just as well anywhere else.
The app is free and ad-supported. A banner ad runs at the bottom, and a brief interstitial appears only at export or restore moments — it never interrupts logging. If you’re an Android user looking for a clean, no-account blood pressure diary, search for BP Diary – Blood Pressure Log on Google Play and give version 1.1.0 a try.
