SweetMate is an advanced and free glucose monitoring app. Designed by a father of diabetic son, it allows users to add/manage blood sugar levels, track trends and deviations, and export data. The app allows users to manually enter data (For now, I'm working on bluetooth options).
For example, the app allows parents to share their child's data, and various permissions are available, including viewing for the doctor and editing for both the child and parents.
The app is constantly being developed.
