F-sense - App for Chronic Fatigue Syndrom or Long Covid
Conceptual App for monitoring and treatment of pain and fatigue related diseases
About the Project
F-sense is a digital therapeutic concept for chronic fatigue syndrome and long COVID — two conditions where the medical understanding itself is still forming. That made it a discovery project before it was a product project: what should a digital tool even try to do when "managing the disease" doesn't yet mean one thing?
The work translated emerging clinical research — energy envelopes, pacing, symptom triggers — into a prototype patients and clinicians could react to. Not a polished MVP, but a tangible enough version of the idea to test whether it answered the right question.
Project Execution
I led user research with patients and clinicians and built the prototype as a decision instrument — concrete enough to test where the disease space, regulatory framing, and daily user reality could meet.
The prototype mapped self-monitoring (symptom diary, medication, wearable data), pacing tools (the "energy envelope" from CFS literature), sleep and relaxation programs, and clinically-grounded education content.
Claimed clinical benefits included managing relapse, supporting sleep, sustaining therapy adherence, and improving recovery odds.
F-sense did not ship as a certified product. It did exactly what a prototype should do: it made the strategic decision tangible, fast.
