## What is Blood Sugar Calendar?

Blood Sugar Calendar lets you log a reading in 3 seconds, right where you measured it!
A blood sugar diary where a calendar and graphs make your trend easy to read. Keep logging and find your body's pattern.

Perfect for you if:
■ You check your blood sugar daily but writing it in a notebook is a chore
■ You want to see fasting and post-meal numbers separately
■ You need to show your readings at a doctor's appointment
■ You're curious how food affects your blood sugar
■ You want to keep insulin doses and medication in the same place

Features:
■ Enter the number and you're done — log in 3 seconds, several times a day
■ Timing labels: fasting / before meal / 2 hours after meal / bedtime / other
■ Judged against a different target per timing — 160 is high when fasting, in range after a meal
■ Calendar color-coded by low / in range / high / very high
■ Trend graph by period, in-range percentage, and average by timing
■ Record the meal, insulin units and medication alongside each reading
■ Set your own target range (use the one your doctor gave you)
■ Switch between mg/dL and mmol/L
■ Dark mode, PIN lock, reminders, backup/restore
■ Cozy handwriting fonts and a paper-textured design

All records stay on your phone only. Your readings are never sent anywhere.

* This app helps you keep records. It does not provide medical diagnosis or prescriptions. If a reading worries you, please consult a healthcare professional.
