The Dr. Cardio app does not require any type of internet connection, this means that users can use the app to conduct ECG records and generate reports without needing to have access to Wi-Fi or mobile data.

The benefit of an app that does not require an internet connection is that it can be used in areas where internet connectivity may be limited or unavailable. For example, users may want to conduct ECG tests while on a hike in a remote area or while traveling in a location where internet connectivity is poor.
