To Determine whether use of the Respimetrix flow test device a) can determine "good" versus "poor" inhaler techniques, and b) the effects of the inhaler training on technique.

Good metered dose inhaler (MDI) technique is described as sitting or standing upright with the head slightly tilted back, exhaling fully, and then inhaling slowly and deeply as you activate the MDI. Common mistakes include: not exhaling fully; not inhaling deeply enough; inhaling too quickly, and not activating the MDI at the proper time.

This study will use the Respimetrix device with placebo to assess a patient's inhaler technique, provide training to patients who demonstrate poor inhaler technique, and remotely track a subject's breathing ability over time.

Inclusion Criteria:

• Patients 18 years of age or older
• Current diagnosis of asthma or Chronic obstructive pulmonary disease (COPD) patients
• Patients must be willing and able to provide informed consent to participate in the the study.
• Patients must be able to use a metered dose inhaler

Exclusion Criteria:

• Contraindication to inhaler use
• Tracheostomy
• Incapacitating disability that interferes with the use of the inhaler or execution of the protocol
• Unable to understand informed consent (e.g. non-English speakers)
