About this app

Glucose Guard helps people with diabetes and their caregivers keep everyday blood glucose and insulin records in one place.

Inspired by a family member who recorded blood sugar on paper, the app focuses on simple entry and easy access to past readings. Enter values measured with your glucose meter and review changes over time.

BLOOD GLUCOSE AND INSULIN RECORDS
• Save blood glucose values with the measurement time and fasting, before-meal or after-meal context.
• Record insulin doses and administration times.
• Keep health notes alongside your readings.

CHARTS AND TARGETS
• Review daily, weekly and monthly trends.
• Select a date to see readings throughout the day.
• Set fasting/before-meal and after-meal targets based on the goals agreed with your healthcare professional.
• See your latest reading and recording activity on the home screen.

PDF REPORTS
Create a PDF report with your recorded glucose and insulin data, charts, averages, highest and lowest values, record statistics and a factual summary. Save or share the report for a medical appointment or to review records with family and caregivers.

EVERYDAY RECORDING
Use reminders, back up and restore your records, and read general food and lifestyle guides. A clear layout helps you continue recording without complicated menus.

Glucose Guard is a recording tool. It does not measure blood glucose automatically, diagnose conditions or replace advice from a healthcare professional. Small, consistent records can help you understand your own patterns.
Log fasting and post-meal glucose, view charts and share PDF reports.
