Log your readings and see the bigger picture. This free blood pressure tracker averages multiple readings — closer to how blood pressure is properly assessed — and shows the category of your average. Informational only, nothing is saved.
Tip: take readings at rest, sitting, at similar times of day. Categories use common AHA adult ranges. Your clinician may set different personal targets.
How the Blood Pressure Tracker Works
The Blood Pressure Tracker lets you log several readings in one sitting and averages them — closer to how blood pressure is properly assessed than relying on a single number — then shows which reference category the average falls into.
Formula: Average systolic = sum of logged Systolic values ÷ number of readings (rounded). Average diastolic = sum of logged Diastolic values ÷ number of readings (rounded). Average pulse = sum of logged Pulse values ÷ number of readings that included pulse (rounded). The averaged systolic/diastolic pair is then matched to a category, checked in this order: systolic > 180 or diastolic > 120 = Hypertensive crisis; systolic ≥ 140 or diastolic ≥ 90 = Hypertension stage 2; systolic 130–139 or diastolic 80–89 = Hypertension stage 1; systolic 120–129 and diastolic < 80 = Elevated; systolic < 120 and diastolic < 80 = Normal.
- Systolic — the top number of each blood pressure reading you log
- Diastolic — the bottom number of each blood pressure reading you log
- Pulse (optional) — your heart rate for that reading, if your monitor shows it
Example Scenarios
| Logged readings (systolic/diastolic) | Average | Category |
|---|---|---|
| 118/76, 122/78, 116/74 | 119/76 | Normal |
| 124/78, 126/76 | 125/77 | Elevated |
| 128/82, 132/84 | 130/83 | Hypertension stage 1 |
| 145/92, 150/95, 138/88 | 144/92 | Hypertension stage 2 |
| 185/115 | 185/115 | Hypertensive crisis |
| 108/68, 112/70, 110/72 | 110/70 | Normal |
Blood Pressure Tracker FAQ
How many readings should I log before checking the average?
The tracker works with as few as one reading, but averaging several resting readings — taken sitting, at similar times of day — gives a steadier picture than a single number, closer to how clinicians assess blood pressure over multiple checks.Why does the tracker use an average instead of a single reading?
A single reading can be skewed by stress, activity or the moment you take it. Averaging several readings smooths out that noise, which is why clinical guidance often relies on multiple measurements rather than one isolated number.What do the blood pressure categories mean?
The tracker groups your averaged reading into Normal, Elevated, Hypertension stage 1, Hypertension stage 2 or Hypertensive crisis, based on common AHA adult reference ranges. These are general categories, not a diagnosis — your clinician may set different personal targets.Is my data saved when I close the page?
No. Readings you log are kept on the page only for your current session and aren’t saved to an account or sent anywhere. Refreshing or closing the page clears your log.Can this replace my blood pressure monitor or a doctor visit?
No. This tracker only averages and categorizes numbers you type in — it doesn’t measure your blood pressure itself. You still need an actual blood pressure monitor to take readings, and a doctor to interpret them properly.Why does the “Elevated” category require diastolic under 80 as well as systolic 120–129?
Elevated blood pressure is specifically defined by a slightly raised systolic number with a still-normal diastolic number. If diastolic also climbs to 80 or above, the reading is categorized as Hypertension stage 1 instead, even with the same systolic value.Related Calculators
