Diabetes is a life-altering disease and its management is not easy. It required a life-changing routines and personal discipline.

Diaguard originally started by Philipp Fahlteich who is a software developer from Germany. Philipp identify himself as:

Furthermore, Diaguard is open-source, which means it can be examined by developer's community for bugs, security issues and malicious scripts.

Why it exists?
Diaguard exists for three reasons: for learning, for fun and for saying thank you. This app kickstarted the career of a professional software developer by leading through the whole software lifecycle: creating a concept, building software from scratch, publishing it to the masses and maintaining a legacy project with additions sprinkled here and there.
Additionally, it was and is pure fun to enhance this app and to see feedback from a helpful and thankful community. Last but not least Diaguard is a way of giving something back.
The app is written in Java then migrated to Kotlin, it uses SQLite as the primary local database.
The project is released under the open-source GPL-3.0 License or later.
