The AQI is displayed in a clear and concise manner, making it easy to understand even for those who are not familiar with air quality data.

Overall, Sameer is a great app for those who want to stay informed about the air quality in their area. The complaint registration feature is also a useful addition, allowing users to report any concerns they may have about air pollution. This app is a must-have for those who are concerned about the quality of the air they breathe.
