The goal of this study is to find out if a smartphone-based program (called 3S-C) can help people with COPD live better, healthier lives. It will also look at how the program affects their knowledge, habits, and overall health. The main questions the study wants to answer are: * Does the 3S-C program help people with COPD feel better and improve their quality of life? * Does it help them understand and manage their condition better? * Does it improve their health, such as reducing breathing problems or making it easier to sleep? * Can it reduce the need for hospital visits or other healthcare? Participants will be split into two groups: The 3S-C group: They will use the smartphone-based program, which includes: (i) Two short individual sessions to motivate them, (ii) helpful messages sent through apps like WhatsApp or WeChat; (iii) support through personalized messaging, phone calls, and a hotline; (iv) an online platform to track their health; and (v) a group session to connect with other COPD patients. The general hygiene (control) group: They will get information about staying healthy, such as tips on hand washing, food safety, keeping their home clean, and better sleep habits. What will participants do? Take part in the study for 12 months. visit the clinic for checkups and complete surveys and simple fitness tests at the start, after 4 months, and after 12 months. Researchers will check if the 3S-C program improves: * quality of life and how well people manage their condition. * habits like taking medication on time, exercising, eating well, or quitting smoking. * health outcomes like breathing, sleep, or feeling less anxious or depressed. This study will compare the 3S-C program to general hygiene tips to see if using a smartphone can make living with COPD easier and healthier.
