Private by design

Your journal stays on your iPhone. BP Diary has no accounts and no servers, and it doesn't use analytics or tracking. We never see your health data.

  • No tracking

Important: BP Diary is a personal tracking tool, not a medical device. It does not measure blood pressure or blood sugar — readings are entered from your own devices. Camera heart rate results are estimates for reference only. The app does not diagnose, treat or prevent any condition. Always consult a qualified healthcare professional, and in an emergency call your local emergency number.
