Brief summary
To determine the usability and technical aspects of Cordio HearO™
Detailed description
The system (including App and server) will be tested under simulated use conditions with representative users to identify potential changes required to the application user interface, to improve user performance and satisfaction, and to inform future design options. The recordings data will also be used for algorithm improvement

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Patient Usability success defined as: 1.Total and individual usability score of ≥3 in the usability questionnaire in ≥80% of the users. | 2 years | The used scale is: Usability questionnaire for the Cordio HearO™ App. This Usability questionnaire is a subjective evaluation based on Likert score of device user satisfaction. Maximum value for each item: 5 Minimum value for each item: 1 Higher scores means a better outcome |
| Patient Usability success defined as: 2. Total Compliance | 2 Years | The total compliance will be determined by the total number of recording days. Success will be considered if total average compliance of 70 % of all days. |
