The participants will be instructed to continue their daily routine, track their daily steps with a pedometer, and record their daily steps on the "Activity Log" paper form.

The participants will be trained how to use the mobile application (Heart Failure Health Storyline (HFHS)) to track their health status, physical activity, manage their medications schedule, and explore the other features that the application has. Additionally, they will receive a pedometer to track their daily steps and record their data on the mobile application.

The participants will be educated to use the HFHS application to monitor their daily vital signs (HR, BP, body weight), physical activity, and medications for 4 weeks.

The research team will monitor their data entry remotely via the HFHS App. The team will text the participant via the App if one or more of following conditions is noted:

• The vital signs show undesired readings
• The records on the HFHS App show that the participant did not take the medications as the schedule says

In addition, the team will call the participant 3 days later to follow up regarding the participant's action towards the text message that the team sent.

The Quality of Experience (QoE) survey will be used to measure the quality of experience in using the mobile application
