Blood Pressure Interpreter

The Blood Pressure Interpreter by Ufumbuzi turns the two numbers from a home monitor into a plain-language reading. Enter systolic and diastolic values and it shows the adult category, explains what that category means and suggests what to do next. It also keeps a private history on the device and prints a clean report for an appointment.

What it does

• Interprets both numbers. It does not stop at the systolic value: it uses systolic and diastolic, and the higher number decides the category when one of them is high.
• Uses the 2017 ACC/AHA adult categories. It separates normal, elevated, stage 1, stage 2 and hypertensive crisis, and also flags a low reading when appropriate. It explains that 120/80 already falls into stage 1 under this guideline, something many older charts do not make clear.
• Keeps a local history. Every reading is stored with its date in the browser, next to a chart of the last ten readings, the latest value and the average. You can clear it whenever you want.
• Prints or saves a PDF. The button opens the browser print dialog; you can print the report or choose “Save as PDF”. It includes the date, systolic, diastolic and category for every reading.
• Works offline and in two languages. After the first load it is cached as a PWA, switches between English and Spanish on the same page and needs no account.

Why the 120/80 example matters

Under the 2017 ACC/AHA categories, normal is below 120/80. A reading of exactly 120/80 falls into stage 1 because the diastolic number is 80. Many older charts still call 120/80 normal; this app follows the guideline and says so directly, so there is no doubt when comparing a reading with the category.

What it does not do

It is not a blood pressure monitor, a diagnosis or a treatment plan. It does not measure pulse, oxygen or arrhythmias, and it does not sync to the cloud. The categories are for adults; children, pregnancy and dialysis need different guidance. Do not change medication based on this app.

Privacy and practical use

Readings are stored only in the browser on your device. There is no account, no advertising and no server upload. The history is useful for spotting patterns between appointments: record two readings a minute apart, keep the dates and show the printed report to a healthcare professional. Clearing browser data deletes the history, so print a copy first if you need one.

For other body measurements, the body measurement calculator covers weight, waist and body fat, and the medication reminders app keeps a schedule.
