Glucio: Blood Glucose Tracker

Glucio is a free blood glucose tracker you can fill in within seconds. Type the number from your meter, add your insulin if you take it, and you are done. Your readings build into a blood sugar log book you can share with your doctor as a PDF. No account, no meter to pair, nothing to sync. LOG IN SECONDS Tap Add reading and one screen opens with a large number keypad. Type 142, or 7.9 in mmol/L, and Glucio tags the meal from the time of day: before breakfast, after lunch, bedtime. One tap changes the tag. There are no scroll wheels. HI and LO from your meter have their own buttons, so no invented number enters your log, and a likely typo such as 1420 gets a quick "Is this correct?". A full entry with a meal tag and a rapid insulin dose takes about six taps. INSULIN & CARBS IN ONE ENTRY Below the glucose field sits an insulin row. Pick the type (rapid, short, intermediate, long, mixed or other), name it the way your prescription does and type the units you injected, in steps of 0.5. Carbs, tags such as Exercise or Sick, and a note are optional on the same screen. An evening basal shot can be saved on its own. Glucio works as an insulin injection tracker: it records what you entered after injecting and never suggests an amount. MG/DL OR MMOL/L Pick your unit on the first screen and switch at any time; every reading, chart and PDF follows. mmol/L values keep their decimal point, and "7,9" is read as 7.9. The built-in blood glucose converter shows 7.9 mmol/L next to 142 mg/dL. Each unit has its own default targets, and you can set the ranges agreed with your care team. ESTIMATED A1C — HONESTLY The estimate appears only when your log can support it: 30 days with readings and about three a day over the last two weeks. Until then the tile counts the days so far. It applies the published ADAG formula to your last 90 days and shows % and mmol/mol, such as 6.4 % (46 mmol/mol), with the number of readings behind it and a clear "not a lab result". Add your lab A1c with its date to see both side by side: an A1c calculator for your own numbers. A LOGBOOK PDF FOR YOUR DOCTOR History switches between a list and a grid laid out like a paper diabetes log book: one row per day, with the year, and columns for night, before and after each meal, and bedtime. Values outside your targets print in bold with ▲ or ▼, readable in black and white. Page one sums up the period: readings, average, time in range, lows and highs, estimated and lab A1c, daily insulin by type. Choose 7, 14, 30 or 90 days, a custom range or all time. PDF, CSV and printing stay free for every range. NO ACCOUNT. NO BLUETOOTH. NO CLOUD. Open the app and log, even in airplane mode. Glucio never asks for an email and never signs you out. Your blood sugar log stays on this phone and out of Google backup; save a backup file yourself, with an optional password, to move to a new phone. REMINDERS & WIDGETS Up to three reminders a day to check; the lock screen only says "Time to check". A Quick Settings tile and a 2×2 widget open the entry screen in one tap. GLUCIO PRO Everything above is free. Pro adds: - Daily pattern by hour of day, 90-day and 1-year charts, two periods compared. - A charts page in your PDF (one included). - Reminders for each insulin, with Logged and Skipped on the notification. - Family profiles: a separate log for a parent or partner. - A 4×2 widget and four more themes. Pro also removes ads. A short video you choose to watch opens the daily pattern, a theme or a second profile for 60 minutes, or adds one PDF with charts. Pro is monthly, yearly or a one-time Lifetime purchase; subscriptions renew until canceled in Google Play. Important: Glucio is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. It does not measure blood glucose and does not calculate insulin doses. Use a glucose meter and follow your care team's advice.
