Logging a Glucose Reading

VitalSync lets you log glucose readings manually at any time — no connected device required. Readings are stored on your device and feed directly into the NeoVital graph on your Dashboard.

Step-by-Step

Open VitalSync and tap the Blood Sugar tab.

Tap the + Log Reading button (bottom of the screen).

Enter your glucose value using the numeric keypad.

Select your unit — mg/dL or mmol/L (set your default in Settings > Units).

Choose a reading type:

Type	When to Use

Fasting	First reading of the day, before eating or drinking anything except water
Pre-Meal	15–30 minutes before a meal
Post-Meal (1 hr)	1 hour after the first bite of a meal
Post-Meal (2 hr)	2 hours after the first bite of a meal — the standard clinical check
Bedtime	Last reading before sleep
Random	Any time outside the above contexts

Confirm the date and time (defaults to now; tap to adjust if logging retroactively).

Add an optional note (e.g., "after exercise", "high-carb meal").

Tap Save.

Where Your Reading Appears

Blood Sugar tab — listed in reverse chronological order with reading type badge and colour-coded value (green for in-range, amber for borderline, red for out-of-range based on your personal targets)
NeoVital graph — the Blood Glucose line updates immediately with your new data point
Projected A1C — the rolling 90-day average recalculates automatically

Setting Your Target Range

Go to Settings > Health Targets > Blood Sugar to set your personal fasting and post-meal target ranges. These targets determine the colour coding on each logged entry and the reference band on the NeoVital graph.

Clinical reference: The American Diabetes Association recommends a post-meal (2-hour) target of < 180 mg/dL (< 10.0 mmol/L) for most adults with diabetes. Always follow the targets set by your own healthcare provider.

Editing or Deleting a Reading

Tap any entry in the Blood Sugar tab to open it, then tap Edit (pencil icon) or swipe left and tap Delete.
