Wynd is a free lifestyle app developed by Wynd Technologies Inc. The app aims to provide users with personalized air quality insights to help them take the right actions to stay healthy and happy. The app delivers real-time data on AQI, PM2.5, Ozone, CO, and NO2 sourced from certified institutions and governmental air quality stations to help users understand their outdoor air quality levels.

The app also offers personalized, real-time air quality readings through the Wynd Tracker, allowing users to track their personal exposure to air pollutants. Users can view their air quality over time, including exposure over hours, days, weeks, months, and years, and export historical levels of personal air quality exposure in CSV. The app also enables users to connect their Wynd Portable Purifier to control the purification level remotely, automatically purifying the air based on the user's personal air quality to create a bubble of clean air around them at all times. Users can also monitor filter levels for optimal purification performance and receive a notification when the filter needs to be replaced.

Wynd is an efficient and useful app for anyone concerned about their air quality, providing personalized solutions to improve their health and well-being.
