Case Study: Michael Hayes of Add Jam improves ME/CFS PEM tracking with PEM Diary

Michael Hayes builds PEM Diary in 2 weeks with Add Jam

Add Jam's cofounder Michael faced a personal challenge with suspected post-exertional malaise (PEM) episodes, a condition associated with ME/CFS and Long COVID. He lacked a clear and efficient way to track these health events, leading to difficulties in receiving proper medical attention and understanding his personal triggers, as existing health apps did not cater to this specific need.

Add Jam developed PEM Diary, a React Native mobile app that serves as a private, on-device tool for logging PEM episodes. The solution provides an intuitive interface for tracking symptoms and severity, and includes features like sleep aids and data export. For the customer, this created an objective record of his condition to facilitate better healthcare consultations and helped evolve a personal tool into a valuable resource for the broader ME/CFS community.
