iPhone
Giant numbers for blood sugar. Log in seconds, show your doctor a clean history. 14 days with everything open, logging free forever. One purchase, no subscription.
The blood sugar journal made for seniors — and everyone who hates squinting.
Sugar Log XL does one thing perfectly: it keeps your blood sugar readings in giant, readable numbers. Log a reading in seconds with one big wheel, tag it (fasting, before or after a meal, bedtime), and show your doctor a clean history.
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'S 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 who wants to replace a paper logbook with something that fits in a pocket
DAY AND NIGHT
Light and dark mode with the same giant numbers. Readable on the nightstand at 6 a.m. and in the kitchen at noon.
MADE TO BE EASY
• Giant numbers and big buttons on every screen
• Log a reading in seconds — the wheel remembers your last value
• mg/dL or mmol/L — match your meter in one tap
• Clear history, newest first
FOR YOUR DOCTOR
Export all your readings as a simple report your doctor can read at a glance.
PRIVATE BY DESIGN
Everything stays on your iPhone. No account, no cloud, no analytics, no adverts.
SIMPLE PRICING
Last 14 days of history free — logging is never limited. One purchase unlocks your full history and doctor reports forever. No subscription.
Sugar Log XL is a journal. It does not measure blood sugar and does not give medical advice.
