## About

TidalSense is a UK-based healthtech startup that has developed AI-powered technology to significantly reduce the testing time for lung diseases, starting with COPD (chronic obstructive pulmonary disease).

The company aims to transform respiratory diagnosis, making it more accessible and efficient, particularly for underserved communities.
