Everyone knows fatigue is dangerous and costly.

But what to do about it? There haven’t been tools to make fatigue risk management decisions easy. Until now.

How does it work?


Our systems integrate with your scheduling and logging systems to import your workers’ duty schedules. You can analyze historical data as well as run scenarios to plan future schedules.

Import work schedules from your scheduling application.


Fatigue Meter’s algorithms apply the latest, peer-reviewed science to analyze your operational data. Our proprietary Off-Duty Behavior model estimates individual sleep periods and fatigue levels. Then predictive analytics give you a picture of each worker’s expected fatigue profile several days forward. Download more information about our fatigue model.


Our user-friendly dashboard lets you explore options to mitigate fatigue risk in upcoming schedules. Once your team decides on the best approach, you can proceed to implement the necessary changes in your scheduling system.

Spot fatigue risk and make the necessary scheduling changes before something happens


Whether it’s real-time monitoring or developing future work schedules, our tools help you maintain a safe and high-performance operation. Use our custom performance metrics to grade the safety of future schedules and evaluate the impact of planned process improvements.

Spotting fatigue risks ahead of time allows you to fine-tune upcoming schedules to maximize safety.

Originally developed for NASA and DOD, our technologies offer the best in security, performance, and ease of use.

“We have been using Fatigue Meter for several years.  Every pilot is able to upload his or her FOS flight schedules and Fitbit sleep data into Fatigue Meter. It provides invaluable insight into personal fatigue. By allowing each pilot to input their proposed rest period into Fatigue Meter prior to flight, pilots are able to arrange their rest schedule with a time that will have the greatest impact mitigating their personal fatigue during the flight. It has allowed the Lead PIC to review the fatigue levels for the entire flight and push back on flight schedules where fatigue is predicted to be at an unsafe level and not easily mitigated to a lower level. Being IS-BAO stage III, we have used this data as part of our Fatigue Management plan. ”
