Open Beta Launching April 10
Explore Fatigue With Your Wearable Data
A free research beta: connect your smartwatch, log how fatigue feels, and review patterns from your own data alongside optional model outputs.
iOS: Get notified when the app goes live on App Store.
Android: Receive private beta email and download instructions.
Developed as part of a PhD programme in digital health
Built from 3+ years of doctoral work in digital health and wearables
Made by digital health researchers, not a commercial product team
The Story Behind FatigueSense
FatigueSense was created to translate doctoral research into a tool people can try in daily life: visualise fatigue patterns, compare them to wearable signals, and use optional models to support self-management.
FatigueSense grew out of doctoral research on how wearable signals and self-reports relate to perceived fatigue over time.
It is aimed at adults living with persistent fatigue linked to long-term health conditions. Fatigue is not one thing: experiences differ widely, and the app does not assume all conditions behave the same.
The beta combines wearable data, check-ins, and exploratory models so you can reflect on your own trends. Outputs are assistive and statistical; they complement your judgment and are not validated for every diagnosis.
Who FatigueSense Is For
People tracking fatigue
Use structured logging and wearables to see day-to-day variation and how it lines up with your own ratings. Useful if you already pace by experience and want an objective layer to compare.
People with fatigue linked to long-term conditions
Many conditions involve fatigue, PEM, or symptom fluctuation in different ways. The app may be relevant for some people with e.g. long COVID, ME/CFS, MS, or cancer-related fatigue, with the caveat that models are not condition-specific unless stated in future studies.
Anyone trying the beta
Optional summaries and “what-if” views support reflection. They do not replace your own judgment, peer-informed pacing, or care from a clinician.

Frequently Asked Questions
FatigueSense is a free, research-oriented mobile app. It links wearable data and your check-ins to views of how fatigue and related symptoms vary over time. It does not diagnose or treat any condition.
Adults who want to take part in research-oriented tracking of fatigue, including people with chronic conditions where fatigue is prominent. It may not be useful for everyone; some people already know their limits better than any model.
Yes. FatigueSense open beta version is free.
On iPhone, FatigueSense supports Apple Watch, Oura Ring, Polar, Withings / ScanWatch, WHOOP, Garmin, Huawei, Xiaomi / Amazfit, and Fitbit.
On Android, FatigueSense supports Fitbit, Google Pixel Watch, Garmin, WHOOP, Oura Ring, Withings / ScanWatch, and Polar. Additional Android wearable support is expanding.
It is built as a research translation project: we study how wearable signals and self-reports align in real life, and share optional model outputs alongside your data. We do not promise a proven clinical pathway for every user.
