DiabetLog is a digital diabetes logbook, not a medical device. You keep measuring with your own meter or CGM; DiabetLog keeps the history organised, shows you the trend and gets it to your doctor.
Track your blood sugar on visual charts and easily analyse how your levels change over time.
No account required, no data sent to servers. Everything stays private on your device.
DiabetLog is built around one idea: make logging so quick that you actually keep doing it. Add a reading, choose the time of day and a tag such as fasting, and you're done. There are no forms to fill out and no account to create.
Every reading feeds an interactive chart of your blood sugar history. Averages and in-range statistics help you see how your levels change over time, and custom target ranges — the ones your care team gave you — show at a glance which readings were high, low or in range.
Set reminders for the times you usually test so measurements don't get skipped. A consistent log is far more useful to you and your doctor than an occasional one.
Generate a readable PDF report of your blood sugar history and share it by email or message before an appointment. You arrive prepared, and your doctor sees the full picture instead of a few remembered numbers.
On iPhone, DiabetLog can sync blood glucose readings with Apple Health, so your data lives alongside the rest of your health information. The integration is optional and happens on your device.
Your readings are stored only on your phone. DiabetLog doesn't require an account, doesn't upload your data to a server and doesn't sell it. Delete an entry or the app and the data is gone.
DiabetLog is free to download. Logging, charts, reminders and statistics are included; Premium unlocks unlimited entries and PDF doctor reports.
