Subjects has provided informed consent prior to initiation of any study specific activities/procedures.

Age more than 21 to less than 85 years at signing of informed consent.
Diagnosis of heart failure, defined as requiring pharmacologic treatment for heart failure, with NYHA class I to class III at most recent screening assessment
Screening within 30 days after Clinic Visit or hospitalization for heart failure - either as a primary or secondary diagnosis.
History of (within the past 6 months) or current use of diuretics.
HF patient who is willing to comply with study restrictions including Everion device management (wearing and charging the device), Apple watch Series 4 and above device management (wearing and charging the device) and BiovitalsHF Patient App Management (pairing Everion device and Apple watch Series 4 and above and BiovitalsHF Patient App, and carrying the smartphone for answering questionnaires and data reporting)

Exclusion Criteria

Subjects are excluded from the study if any of the following criteria apply:

Disease Related

Other Medical Conditions

Malignancy except non-melanoma skin cancers, cervical or breast ductal carcinoma in situ within the last 5 years
Hospitalization with any pathology that may meaningfully interfere with functional tolerance, cardiopulmonary capacity or mobility within the 30 days prior to screening.
Estimated glomerular filtration rate (eGFR) < 20 mL/min/1.73 m2 or receiving dialysis at screening.

Prior/Concomitant Medication

1. Currently receiving treatment or procedure in another investigational device or drug study.

Other Exclusions

Likely to receive during the duration of the study, in the opinion of the investigator, planned revascularization, implantation of ICD or CRT, ventricular assist device, continuous or intermittent inotropic therapy, hospice care, or cardiac transplant.
Implantable cardioverter defibrillator or initiation of cardiac resynchronization therapy (CRT) (with/without implantable cardioverter defibrillator) within 30 days prior to enrollment.
Recipient of any major organ transplant (e.g. lung, liver, heart, bone marrow, kidney).

Subject likely to not be available to complete all protocol-required study visits or procedures, and/or to comply with all required study procedures (e.g. Clinical Outcome Assessments) to the best of the subject and investigator's knowledge.
History or evidence of any other clinically significant disorder, condition or disease (with the exception of those outlined above) that, in the opinion of the investigator, if consulted, would pose a risk to subject safety or interfere with the study evaluation, procedures or completion.
