Bronchial asthma is a heterogeneous disease characterized by chronic airway inflammation, which is a common and frequently occurring disease in the world, and has resulted in a sustained increase of social and economic burden. However, several studies suggest, lots of asthma patients did not get their asthma controlled. The investigators study showed that in China only 28.7% of asthma patients achieve asthma controlled during 2007-2008. In recent years, application softwares of mobile-phones for asthma have gradually increased, studies suggested that application of these application softwares can make treatment more standard, reduce asthma attacks, help patients to control their asthma, improve adherence and these application softwares also show many other advantages. This study is a prospective, multi center, randomized, controlled study, aims to evaluate the efficacy of application softwares in asthma patients, provide a new tool to asthma management.

Proportion of good adherence at the 6th month
patients will fill out the MARS-A questionnaire on their own，and the MARS-A Scores will be calculated to show their adherence of medication. Good adherence: MARS-A score\>=4.5
Time frame: 6 months
Forced expiratory volume in one second（FEV1）
patients will accomplish the pulmonary function test，and the percentage of actual value to predicted value of FEV1 will be calculated to show their pulmonary function.(The predicted value of FEV1 can be calculated when age,gender,height and weight are already known.)
Time frame: 1 year
Forced vital capacity(FVC)
patients will accomplish the pulmonary function test，and the percentage of actual value to predicted value of FVC will be calculated to show their pulmonary function.
Time frame: 1 year
Peak expiratory flow(PEF)
patients will accomplish the pulmonary function test，and the percentage of actual value to predicted value of PEF will be calculated to show their pulmonary function.
Time frame: 1 year
Emergency visits
patients will report their times of emergency visits to the researchers.
Time frame: 1 year
Hospitalization
patients will report their times of hospitalization to the researchers.
Time frame: 1 year
Asthma Control Test（ACT）
patients will fill out the ACT questionnaire on their own，and the ACT Scores of 25 is classified as well-controlled asthma，between 20 and 24 as not well-controlled，and less than 20 as poorly controlled asthma. ACT score is used to describe the proportion of people with different levels of asthma control.
Time frame: 1 year
Proportion of good adherence
patients will fill out the MARS-A questionnaire on their own，and the MARS-A Scores will be calculated to show their adherence of medication. Good adherence: MARS-A score\>=4.5. Compare the proportion of good adherence change with time, time points: 1st month, 2nd month, 3rd month, 6th month, 12th month.
Time frame: 1 year
Asthma Quality of Life Questionnaire(AQLQ)
patients will fill out the AQLQ questionnaire on their own，and the AQLQ Scores will be calculated to show their quality of life.
Time frame: 1 year
Correct answer rate of the given asthma awareness questions
patients will answer 4 questions about asthma, correct answer rate will be calculated to show their awareness of asthma.
Time frame: 1 year
Fractional exhaled nitric oxide(FeNO)
patients will accomplish the fractional exhaled nitric oxide test，and the result of fractional exhaled nitric oxide related to airway inflammation.
Time frame: 1year
