This is a pilot study to evaluate the role digital inhaler technology on patients with obstructive lung disease in preventing admissions and exacerbation, as well as improving symptom control. The primary objective is to evaluate feasibility of study protocol, patient recruitment, and patient retention with goal recruitment of 20 participants, 60% recruitment success, and 60% retention rate for 6 months duration. The secondary objectives are the evaluation of patient admission rate, exacerbation rates, and symptoms control with use of digital inhaler technology The subject population will be patients with physician diagnosed obstructive lung disease.

Inclusion Criteria:

• Any sex
