MDConx is a text communication application designed as a closed system for use in specific medical institutions. Users can text any member in this closed system but joining the system is by invitation only. The app also has features specific to physician uses, such as group formation that can be visibile or private to the institution. It also has pager forwarding (via an mdconx.com email address). The app also has standard texting application features such as the ability to designate certain users or groups as favorite.
