About this app

SugarBook – your free diabetes diary with no ads, no account required, and data stored exclusively on your phone!

With SugarBook, you can easily and clearly document your blood glucose levels, lab results, notes, and meals on your smartphone.

The app is designed for people who want to regularly record their values ​​and keep better track of them – clearly, locally, and without unnecessary clutter.

Here's what SugarBook can do:

Document blood glucose levels
Record your blood glucose levels manually or using the scan function of your meter. Save the date, time, measurement time, insulin doses, and personal notes.

Track and analyze your progress
Keep track of your values ​​with clear lists and charts. Filter by different time periods and see your personal progress.

Share PDF reports
Create a PDF report with charts and all blood glucose values ​​for the selected period. Ideal for presenting your documentation at your doctor's appointment or for your own archive.

Carbohydrate Calculator for Meals

With the integrated carbohydrate calculator, you can search for foods, enter quantities in grams, or directly record carbohydrate values. The app calculates the total carbohydrate content and, if desired, transfers it to your notes.

The food data in the carbohydrate calculator is based on the German Federal Food Code (BLS), source: blsdb.de.

Record Lab Results
Document important lab results and keep track of them over the long term.

Set Reminders
Set simple measurement reminders, for example, in 30 minutes, 1 hour, 2 hours, or 3 hours.

Export and Backup
Save your data locally and export it as needed. You decide when and with whom you share your data.

Local and Clear
SugarBook is designed as a personal diabetes diary. Your entries are recorded locally on your device. Sharing, exporting, or backing up is done only by your own action.

Important Note:
SugarBook is intended solely for personal documentation. This app does not replace medical advice, make diagnoses, or provide therapy or insulin recommendations.

SugarBook is right for you if you:

want to easily document your blood glucose levels
want to record measurement times, insulin doses, and notes
want a clear overview of your readings
want to create a PDF for doctor's appointments
want to document meals with their carbohydrate exchange values
