Read your monitor's display with the camera or enter by hand. Two readings each morning and evening, averaged for you, and one sheet for your doctor. No sign-up, no ads. Two readings each morning and evening. The app does the averages. BP Book is a simple journal for the readings from your own blood pressure monitor. Point your camera at the monitor's display, check the numbers, then save, or enter them by hand. At your doctor visit, show one sheet with your morning and evening averages and each day's readings. ■ Read with camera ・Hold your own monitor's display up to the frame and the SYS, DIA and pulse numbers are read. No shutter needed. ・You always check the numbers against the display before saving. Fields worth a second look are marked "Check". ・Images are not saved. If it doesn't read well, just enter the numbers by hand. ・BP Book is not a blood pressure device. It only reads the numbers shown on your own monitor. ■ AM 1, AM 2, PM 1, PM 2 ・The slot is picked from the time you add a reading (morning 4:00–11:59, evening 17:00–3:59). ・The average of the two readings is shown large. Both readings are kept. ・The difference from the last same occasion is shown as numbers (no colors, no judgments). ・Mark when you took your medicine and add notes. ■ Log and trends ・A calendar shows each day's morning and evening averages. ・Trend lines show morning and evening SYS and DIA. ■ Sheet for your doctor ・Morning and evening averages, the number of days, and each day's 1st and 2nd readings with their averages, in large type on one sheet. ・The last 4 weeks are free to view. ・Choosing the period (since your last visit, 90 days, custom) and making a PDF to print, AirDrop or email is Pro. ■ Health ・Read blood pressure and pulse from the Health app (the first 2 morning and the last 2 evening readings go into the slots). ・Readings you add in BP Book are also written to Health. ・Values you entered by hand are never overwritten. ■ Also ・Reminders for your morning and evening readings, and the evening before a doctor visit ・Family records (from the 2nd person, Pro) ・CSV export (opens in Excel) and backup for moving to a new phone ・English and Japanese ■ Price ・Recording, reading with the camera, trends, the on-screen sheet for your doctor (last 4 weeks), reminders, Health, CSV and backup are free. ・Pro is a one-time purchase, not a subscription: the sheet for your doctor as a PDF for any period, all-time trends and family records. ■ Your data ・Your records (blood pressure, pulse and notes) are stored on your device and never sent to our servers or to iCloud. No account needed. ・Anonymous app usage counts (how far you got, how often) and crash reports are sent. They never include your blood pressure values. ・No ads. ■ Please note ・BP Book is a journal for showing the readings you record at home to your doctor. It does not diagnose, treat or give medical advice, and does not judge your values. ・If you have concerns, take your records and talk to your doctor.
