“Unbricking” QardioArm
January 29, 2026
MedM Health Diary is an app by MedM that supports many third party devices, including the Qardio Arm. There is an optional subscription for advanced features, but the basic edition is free, and includes unlimited Bluetooth connections. I do suggest reading up on the limitations before using it. To me, the major limitation of the free edition is that, while it offers some basic data export options, it will not sync your data with health platforms like Google Fit or Apple Health.
Unike the Qardio app, the Health Diary app can be used without registering or loggin in. The start screen prompts you to create an account, or ro login with your Google or Apple identity, but you do not have to do either. The option to "Continue without registration" is merely displayed less prominently, near the bottom of the screen.
