About
Your meter gives you a number and forgets it. GlucoseLog is the blood sugar log that remembers every reading, shows you the week behind it, and turns three months of checks into one clean page for your doctor.
Type the value from any meter or CGM, tag the moment — fasting, pre-meal, post-meal, bedtime — add a note if the reading has a story, and you are done in about ten seconds. GlucoseLog works in mmol/L or mg/dL, compares each entry against a display band you choose, and flags very low or very high values with a clear general-information notice. It is a logbook, not a medical device: it never diagnoses and never suggests insulin, medication or doses.
WHAT YOU GET
• A reading logged in seconds — number, context tag, optional note — saved before your meter powers itself off
• Open the app and last night is right there: your latest value, its context, and where it sits in the band you chose
• The 2pm spike from last Tuesday found in two taps — history grouped by day, filterable to just post-meal readings
• Ninety days of readings on one chart, colour-coded by fasting, meal and bedtime, so the pattern behind the numbers finally shows
• A printable PDF of your readings in your hand at the next appointment, instead of a memory test
• Reminders at the times you actually test, so the log stays complete enough to mean something
PERFECT FOR
• People with type 2 diabetes keeping a fasting and post-meal finger-prick routine
• Gestational diabetes: four checks a day for a few months, and a tidy record for every weekly review
• Prediabetes watchers told to "keep an eye on it" who want proof of progress
• Anyone whose doctor said "keep a log and bring it in"
WHY NOT JUST USE YOUR METER'S APP?
Meter apps lock you into one brand, ask for an account, and bury your history behind sync screens. Paper logbooks stay home on appointment day. GlucoseLog takes readings from any meter or CGM you use, keeps them on your phone, converts between mmol/L and mg/dL, and produces a PDF or CSV the moment you need one.
PRIVATE BY DEFAULT
Your readings stay on this iPhone. No account, no cloud, no analytics — the only network traffic is Apple's App Store handling purchases. Exported reports go only where you choose to send them.
FULL ACCESS
GlucoseLog Pro unlocks the complete toolkit: 7, 30 and 90-day trend charts, within-band summaries, averages by meal context, record-coverage counts, PDF reports, CSV export and daily reminders. Choose a weekly or yearly auto-renewing subscription, or a one-time lifetime purchase. Prices are shown before you confirm, and subscriptions can be cancelled anytime in your App Store settings.
Log your next reading in GlucoseLog — by your next appointment it will have three months of company.
