1. Three ways to record, in seconds.
Type systolic, diastolic and pulse into large fields; scan your meter's screen with the camera, recognised on the device, with the photo neither stored nor uploaded; or hold the mic and say "125 over 88, pulse 85", recognised on the device with no audio kept. Every value lands on a confirmation screen first — only Save writes it, so no reading is ever recorded silently.
2. 7- and 30-day trends at a glance.
Two-line charts for systolic and diastolic, switching between single readings and daily averages; average blood pressure, morning versus evening, pulse pressure, and which way things have moved since the previous period. Categories use neutral words only — low, normal, high-normal, elevated, high, very high. The app does not diagnose or draw conclusions for you.
3. Every reading kept.
Grouped by day, with the details a tap away: time, morning or evening, pulse and notes. History supports searching by value and jumping to a month, and readings from another year carry the year with them.
4. Measure on time, take medication on time.
Measurement reminders at a fixed time, on chosen weekdays, or every N hours. Medication schedules hold the name, dose and times, and the notification can record Taken / Snooze / Skip directly. All notifications are local — nothing passes through a server.
5. A tidy report before your next appointment.
An A4 layout: overview, on-target rate, trend chart, every reading, plus medication and adherence. The free version exports a 7-day report; Pro adds 14 or 30 days. Share it, print it, or save it to Files for your doctor.
6. In Apple Health, and on your widgets.
Optionally write the primary profile's blood pressure and heart rate to Health and import the last 90 days. Small and medium widgets plus Lock Screen accessories show your latest reading at a glance.
7. Family profiles, kept separate.
The primary profile is free; each additional family profile keeps its own readings, reminders and reports, and that data stays on this phone too.
8. Private by design.
Your readings stay on this iPhone. WenYaJi has no account system, no server, no advertising and no third-party analytics, and your records are never uploaded to us. The only network communication is Apple's in-app purchase (buying or restoring Pro), which Apple handles — we never receive your payment details. Voice is recognised on the device and no audio is kept.
WenYaJi records and helps with lifestyle habits. It is not a medical device, does not diagnose, does not replace a doctor, and never recommends a drug or a dose. At or above 180/120 mmHg it only says to seek care immediately.
Free to download: manual entry, history, 7/30-day trends, lifestyle advice, measurement and medication reminders, Apple Health, widgets, the 7-day doctor report and one profile are free forever, and you can keep using them without buying Pro. WenYaJi Pro comes with a free 7-day trial, then a single one-time purchase that never expires and never renews — unlocking camera scanning, voice entry, extra family profiles, 14/30-day reports, 90-day trends, coefficient of variation and the 7-day home-monitoring average.
Record / trends / reminders / reports, covering the whole way from one measurement to the next appointment.
Time of day: morning or evening marked automatically, the time editable, and a short note if you want one.
A change of medication, or a check-up: gather the recent readings, medication and on-target rate into one PDF.
