• •Diagnosis of asthma, confirmed by spirometry: positive post bronchodilator test (PBT), defined as an improvement of at least 12% and an increment of at least 200 ml in the absolute value of FEV1 following B-agonist inhalation.

• •Subjects must meet criteria of repeatability of spirometry, defined for this protocol purpose as the three highest accepted FEV1 values to be within 0.10L (100mL) of each other or with a variability of 5% or less.
• •Subjects with capacity to handle a smartphone device, with incorporated Android system, and to use and input data on the app ASMATIC, designed for this study purposes.
