Blood Sugar Keeper is a blood sugar management app designed for diabetes patients and their caregivers.

It was developed by focusing on essential features to make the daily tasks of recording blood sugar and managing insulin dosage easier and more convenient.

The initial motivation for creating this app stemmed from family.

While managing his diabetes, the developer frequently saw his father writing down his blood sugar levels on paper or in a notepad. However, there were many instances where he would forget the record or find previous readings after some time.

“I just measured my blood sugar, where should I write this down?”

“What was it earlier?”

These moments repeated more often than expected, and the developer realized that while recording was necessary, complex apps could actually be difficult to use.

Therefore, Blood Sugar Keeper was developed with the goal of creating an intuitive blood sugar recording app that anyone can use easily.

Without complex settings or difficult menus, it is designed to allow users to quickly input blood sugar levels and insulin records, and to check the flow of changes at a glance through charts.

Blood sugar management is not a short-term process; consistent recording and tracking trends are crucial.

We are continuously improving the app so that even small records accumulate to help users understand their health patterns and lead to consistent management habits.

Moving forward, we aim to add more convenient and practically helpful features to become a health management app that both diabetic patients and their caregivers can use without hesitation.
