This is the client app for the Cyfer Health system. The server part of the system has not yet been released but the client is operable in a standalone mode.
The Cyfer Health system monitors the heart rates of "patients". It is primarily aimed at health care organisations but will be also of interest to those with elderly or vulnerable relatives. It uses low cost (~£20/$25) health bands to detect the heart rates and, optionally, daily step counts.
This client app is currently compatible with the Xiaomi MI Smart Band 5 and 6.
