Blood Pressure Diary is a free Android application developed by Sammysoft that allows users to manage their blood pressure values with high data protection. While there are many similar apps available, this one stands out due to its unique feature of not having permission to access the internet, ensuring that users' sensitive health data remains solely on their device.

With the new version 3.0, Blood Pressure Diary now includes the calculation and display of the pulse pressure (blood pressure amplitude), providing users with even more valuable information about their overall health.

The app only requires permission to change, read, and delete USB memory contents, which is necessary for the import and export of saved data. Overall, Blood Pressure Diary is a reliable and secure option for those looking to manage their blood pressure values.
