Kaatru

Kaatru is a powerful and user-friendly Flutter-based mobile application designed to provide real-time air quality data and environmental insights. It allows users to monitor air pollution levels, temperature, and humidity in their surroundings and across multiple locations. With its clean interface, interactive charts, and smart location features, Kaatru helps users make informed decisions about their health and environment.

Real-Time Air Quality Data :
Kaatru fetches and displays live air quality data from trusted sources, giving you the most accurate and up-to-date information. Users can easily view key air quality parameters such as PM2.5, PM10, and other pollutants that impact health and the environment.

Environmental Monitoring :
In addition to air quality, Kaatru provides essential environmental metrics including temperature and humidity levels. By combining these values with pollution data, the app gives users a complete overview of their environmental conditions.

Interactive Map View :
Visualize air quality across multiple regions using an integrated Google Map interface. Tap on any monitoring station to view detailed pollutant readings for that area. The map feature makes it easy to identify cleaner or more polluted regions at a glance.

Data Visualization and Trends :
Track changes in air quality and weather patterns over time using beautifully designed charts. Kaatru uses advanced chart libraries like Syncfusion Charts or fl_chart to represent historical and real-time trends, making the data easy to understand.

Location-Based Monitoring :
The app automatically detects your current location and displays nearby air quality readings. This personalized approach ensures you always have relevant and localized data wherever you go.

User Authentication and Profile :
Kaatru includes secure user authentication powered by JWT (JSON Web Tokens). It safely stores user credentials and session data using Shared Preferences. Users can log in to access personalized features and view their profile details such as name and email.

About Us and User Information :
The Profile page contains an “About Us” section that introduces the mission and vision behind Kaatru, helping users understand the importance of monitoring air quality and staying environmentally conscious.

Smooth Navigation and Modern UI :
Kaatru is built with a simple, elegant, and responsive design that ensures smooth navigation between key pages — Home, Map, Profile, and About Us. The interface incorporates modern icons, soft gradients, and subtle animations for an enhanced user experience.
