GlucoseTracker is a simple, private logbook for your finger-stick blood glucose readings. Log a reading in a few taps, see your patterns in clear charts, and keep your data on your phone. No account, no ads, no subscriptions and no cloud upload.
FAST, ERROR-RESISTANT LOGGING
• Add a reading in a few taps: value, unit, date and time, and meal context
• mg/dL or mmol/L, with date and time set to now by default
• Meal context tags: fasting, before or after breakfast, lunch or dinner, bedtime, or other
• Add an optional short note, like "felt dizzy"
• Built-in checks catch empty, zero or negative values, and ask you to confirm unusual numbers before saving
HISTORY YOU CAN TRUST
• All your readings, newest first, grouped by day
• Each entry shows its value, unit, time, meal context and a range label
• Tap any reading to edit it, or delete it with Undo
• A last-reading card shows your most recent value and how long ago you took it
TRENDS THAT ARE EASY TO READ
• Line charts of your real readings by day, week, month or a custom range
• Points colored by range (very low, low, in range, high, very high), with your target range shaded
• Range labels never rely on color alone
• Filter by meal context to see how readings compare before and after meals
• A summary shows how many readings you logged and the % of readings in each range
REMINDERS THAT WORK OFFLINE
• Set your own reminders with a time, optional weekdays and a label
• Reminders run on your device, with no network or account
• Tap a reminder to go straight to adding a reading
SETTINGS THAT FIT YOUR CARE PLAN
• Switch between mg/dL and mmol/L at any time; your saved readings are not changed
• Default ranges follow the International Consensus on Time in Range
• Adjust your low, high, very low and very high limits with your care team, and reset to defaults any time
SHARE ON YOUR TERMS
• Export all readings or a date range as a CSV file
• Send it through the Android share sheet or save it where you choose
• The CSV opens in any spreadsheet and is easy for a clinician to read
• Nothing leaves your phone unless you start an export
PRIVATE BY DESIGN
• No sign-up and no sign-in
• No ads, no in-app purchases and no subscriptions
• Your readings are stored only in app-private storage on your device
• No analytics or crash reports receive your readings
BUILT FOR EVERYONE
• Large touch targets, strong contrast and TalkBack labels
• Supports large font sizes and dark theme
• Calm, plain wording: "Below target", not "Danger"
