Mine also has 100 logged entries for 3 users. It can display a table or trend line of historical data, and it has a usb port that I believe can be used to download the log. But if you need a specific driver or software to access the file then I don’t know if that violates the “no app” requirement.

I hadn’t tried accessing the data externally before and this post got me curious enough to try. The program looks ancient and does not recognize the bp monitor as is. I don’t feel like playing the driver hunting and compatibolity mode game. I would be tempted to speculate that this is representative of the type of experience to expect if OP doesn’t want to go down the bluetooth connection to app route.
