Sugar Log XL — Blood Sugar Log

The blood sugar journal made for seniors, and for everyone who hates squinting. Sugar Log XL does one thing well: it keeps your glucose readings in giant, readable numbers.

WHAT YOU CAN LOG • Fasting glucose in the morning • Readings before and after meals • Bedtime readings • Any value from any glucose meter: the app is a diary, not a device WHO IT IS FOR • People with type 2 or type 1 diabetes who test at home • Prediabetes and gestational diabetes, when the doctor asks for a log • Sons and daughters helping a parent keep their numbers in order • Anyone replacing a paper logbook with something that fits in a pocket DAY AND NIGHT Light and dark mode with the same giant numbers.
