Setting Your Target Ranges

Setting Your Target Ranges

VitalSync uses your personal target ranges to colour-code every logged entry and to draw reference bands on the NeoVital graph. Setting accurate targets is the single most important personalisation step — it transforms raw numbers into meaningful, at-a-glance health signals.

Where to Find Health Targets

Go to VitalSync > Settings > Health Targets. The screen is divided into three sections: Blood Pressure, Blood Sugar, and Body Weight. Each section has its own set of fields and a Save button.

---

Blood Pressure Targets

Default Values

VitalSync ships with the following defaults, based on the 2023 European Society of Hypertension (ESH) guidelines for adults without specific comorbidities:

How to Customise

Go to Settings > Health Targets > Blood Pressure.

Tap the Systolic target field and enter your provider-recommended value.

Tap the Diastolic target field and enter your value.

Tap Save.

Colour Coding on Logged Entries

NeoVital Reference Band

The NeoVital graph draws a soft green horizontal band across the systolic axis at your target value. Readings above the band are plotted in amber or red; readings within or below are plotted in the line's default colour.

Guidance by Population

The table below summarises commonly used clinical targets. Always follow the target set by your own healthcare provider — these are reference values only.

Blood Sugar (Glucose) Targets

Default Values

VitalSync ships with ADA 2024 general adult targets:

How to Customise

Go to Settings > Health Targets > Blood Sugar.

Select your preferred unit: mg/dL or mmol/L (this also changes the unit displayed throughout the app).

Set your Fasting low and Fasting high values (the green zone for fasting readings).

Set your Post-meal high value (the upper limit for post-meal readings).

Tap Save.

Colour Coding on Logged Entries

Hypoglycaemia alert: Readings below 70 mg/dL (3.9 mmol/L) are always flagged red regardless of your custom target, as this threshold is a universal clinical safety marker.

Guidance by Population

Time in Range (TIR)

VitalSync calculates your Time in Range as the percentage of readings over the past 14 days that fall between your fasting low and post-meal high targets. The ADA recommends a TIR of ≥ 70% for most adults with diabetes. Your TIR percentage is displayed on the Blood Sugar tab summary card.

---

Body Weight Target

Default Value

VitalSync does not set a default weight target — this field is intentionally blank until you configure it, because a clinically appropriate weight goal is highly individual.

How to Customise

Go to Settings > Health Targets > Body Weight.

Select your unit: lbs or kg.

Enter your goal weight.

Optionally set a target date — VitalSync will calculate the weekly rate of change required and display it alongside your current trend.

Tap Save.

Colour Coding and Progress Display

• The Weight tab shows a progress bar from your starting weight (the first logged entry) to your goal weight.
• Entries are colour-coded: green if your weight is trending toward your goal, amber if it has plateaued for more than 14 days, red if it is trending away from your goal.
• The NeoVital graph draws a horizontal dashed line at your goal weight on the Body Weight axis.

Setting a Clinically Appropriate Goal

The table below provides reference BMI ranges from the WHO and NIH. BMI is a population-level screening tool and does not account for muscle mass, bone density, or ethnicity-specific risk thresholds. Use it as a starting point for a conversation with your provider, not as a definitive target.

To calculate a goal weight from a target BMI:

Goal weight (kg) = Target BMI × Height (m)²

For example, for a target BMI of 24 and a height of 1.75 m:

24 × (1.75)² = 24 × 3.0625 = 73.5 kg

Rate of Change Guidance

The NIH and most clinical guidelines recommend a weight loss rate of 0.5 -- 1.0 kg (1 -- 2 lbs) per week for sustainable fat loss without significant lean mass reduction. VitalSync will display a warning if your target date implies a rate faster than 1.5 kg/week, as this may require medical supervision.

---

Resetting to Defaults

To reset any target to its factory default:

Go to Settings > Health Targets.

Tap the section you want to reset (Blood Pressure, Blood Sugar, or Body Weight).

Tap Reset to Default at the bottom of the section.

Confirm. The default values are restored immediately.

Important: The target ranges in VitalSync are for personal tracking and self-monitoring only. They do not constitute medical advice and do not replace targets set by your physician, endocrinologist, cardiologist, or other qualified healthcare provider. If you are unsure what target is appropriate for your health status, consult your care team before making changes.
