LonghaulTracker is a free iPhone app developed by LivLyme Foundation, falling under the Lifestyle category with a focus on Health & Fitness. The app was born out of the founder's personal experience with tick-borne diseases, leading to a journey of creating a tool for logging and tracking TBD symptoms. However, amidst the global pandemic, the app's purpose expanded to help individuals suffering from various diseases, including long-term symptoms, to better communicate with healthcare providers and caregivers.

The app aims to support those dealing with chronic symptoms by providing a platform to catalog and share their health data over time. By facilitating these ongoing conversations, LonghaulTracker aspires to contribute to a healthier and happier community, emphasizing the importance of data sharing in improving overall well-being.
