Blood Sugar Tracker & Glucose1.14.1 - App Store

. Log your blood sugar, weight and notes in seconds
. Get an estimated A1c and see how much of your data is in range
. Export a glucose log as a PDF for your doctor

Blood Sugar Tracker & Glucose is a simple glucose diary for people who have been asked to keep track of their readings at home. Enter what your meter shows, and the app turns it into an estimated A1c, a time-in-range figure, trends and a clean PDF you can hand to your doctor.

The screen is deliberately plain: large figures, few taps, nothing in the way.

■ Main features

. Morning, noon, evening and before bed, with a before-meal and after-meal value at each meal
. Values in mg/dL, mmol/L or g/L, with the unit for your region suggested on first launch
. Weight in kg or lb, and a note for each day
. Calendar view of every day you have logged
. Estimated A1c, calculated from your average glucose
. Time in range: how much of your data sits inside your own target range
. Average, highest and lowest readings for any period
. The gap between your before-meal and after-meal values
. Which time of day tends to run high
. Trend charts: one point per day, or every reading colour-coded by before meal, after meal and before bed
. Full-screen charts with grid lines, your target band and an axis that follows your data
. Periods of 7, 30 and 90 days, or your own date range
. Glucose log as a multi-page PDF, ready to print or send
. CSV export
. Your own target range, and a week that starts on Sunday or Monday

■ An estimated A1c, just for logging

Once you have 14 readings across at least 7 days, the app shows an estimated A1c worked out from your average glucose. Until then it tells you how many readings are still needed, so you always know what your logging is building towards.

■ Who it is for

. People whose doctor asked them to write down their blood sugar at home
. People living with type 2 diabetes who want to see whether things are improving
. People with prediabetes who want to keep an eye on their numbers
. People who would rather keep their paper glucose booklet on their phone

■ A log your doctor can actually read

The PDF is laid out like the paper booklet clinics hand out: every logged day in a table, with your summary at the top. Print it, or send it ahead of your appointment. It is free, with no page or date limit.

■ Your target range, not a generic one

Set the range your doctor gave you, and every reading is shown against that range instead of a one-size-fits-all threshold. Your time-in-range figure follows the same numbers.

■ Nothing to sign up for

No account, no sign-in. Your readings, notes and weight are stored on your device and are not sent to our servers.

■ Free, with nothing locked away

The app is free and supported by ads. There is no premium plan, no subscription and no paywall. Reports, charts, PDF export, CSV export and your complete history are available to everyone, with no limit on how far back you can look.

※ This app records the readings you enter. It does not measure blood sugar and is not a replacement for a glucose meter or a continuous glucose monitor. The estimated A1c is a calculation based on your average glucose, not a laboratory result and not a diagnosis. Always follow the instructions of your doctor or pharmacist.
