HLTH Band · Accuracy Guide
One reading is a moment. Your pressure is a pattern.
Your band and your cuff will rarely show identical numbers, and they do not need to. This guide walks through the three checks that explain almost every mismatch: when you compare, how the band sits, and which wrist you measure on.

Side-by-side test
The short answer
A gap of up to 10 points between your band and an upper-arm cuff is normal and expected. Anything bigger usually comes from one of three things: readings taken at different times, a band that sits wrong, or both devices on the same arm.
±10mmHg
Expected difference between wrist and upper-arm readings
Know your two readings
Two numbers, one story
Your band produces two kinds of blood pressure readings. Comparing the wrong one against a cuff is the single most common reason the numbers look off.
Hourly reading
Taken automatically every 60 minutes and stored in your trend history. The large number on the Blood Pressure screen is always this stored reading, so it can be up to an hour old. Never test it against a cuff reading taken right now.
One Key Measurement
Triggered manually from the home screen. Tap One Key Measurement, then the green button, and the band takes a live reading at that exact moment. Always use this mode when comparing against a medical cuff.
The three checks
Check a reading
A band-to-cuff comparison is only a fair test when all three conditions hold. Work through them in order; most mismatches disappear at check one or two.
Take both readings at the same moment
Run a One Key Measurement while the cuff is measuring. The band updates its stored number every 60 minutes, so an hourly reading compared to a fresh cuff reading taken at a different time will always look different.
A fair timing test
Wear the band the right way
Place the band one finger above the wrist bone, snug, with the sensor flat against the skin. A loose or shifted band reads low, and the gap disappears as soon as the fit is corrected.
Correct placement
Loose or shifted band
Readings in mmHg. Adjust the fit and measure again.
Use opposite wrists
Each device applies slight pressure that can alter the other reading. If the cuff is on your left arm, wear the band on your right wrist, and vice versa.
One device per side

Three situations worth acting on
Within 10 points of the cuff: normal and expected, no action needed. Still not matching after all three checks? Contact support at info@hlthtrack.com.

The HLTH Band is a monitoring tool for everyday wellness tracking, not a diagnostic device. If a reading concerns you, confirm it with a medical cuff and consult a healthcare professional.
Frequently asked
Blood pressure questions, answered
Nine times out of ten it is one of three things: the readings were taken at different times, the band is loose or sitting wrong on the wrist, or both devices were on the same arm. Work through the three checks in this guide in order; most gaps close at check one or two, and a difference of up to 10 points is normal and expected.
Within 10 points in either direction is normal and expected, because the wrist and the upper arm are different measurement sites. If both readings were taken at the same moment, on opposite wrists, with a snug band, a gap of up to 10 points needs no action at all.
Only a One Key Measurement. Tap One Key Measurement on the home screen, then tap the green button while the cuff is running; this produces a live reading at that exact moment. The large number on the Blood Pressure screen is the stored hourly reading, so never use it for a side-by-side test.
The band takes a reading automatically every 60 minutes and stores it in your trend history. The large number on the Blood Pressure screen is always this stored reading, so it can be up to 60 minutes old. For a live number at any moment, take a One Key Measurement.
No. The HLTH Band is a monitoring tool for everyday wellness tracking, not a diagnostic device. It is designed to work alongside your doctor and your cuff: it tracks trends across days and weeks, flags unusual spikes, and lets you share your history for context between appointments. If a reading concerns you, confirm it with a medical cuff and consult a healthcare professional.
Work through the three checks in order: compare a One Key Measurement taken at the same moment as the cuff, check the fit (one finger above the wrist bone, snug, sensor flat to the skin), and use opposite wrists. If the gap is still bigger than 10 points after all three, contact support at info@hlthtrack.com.
