The best Fatigue Management tool getting better!

This is the most advanced Fatigue Management tool available based on a commonly used fatigue model of calculating an Individual Fatigue Likelihood Score (IFLS). By simply setting the hours when slept/awake or on duty, Fatigue Predictor will automatically generate the IFLS prediction and flag duty limits. The app offers many parameters to adjust the calculations to specific Fatigue Risk Management System (FRMS) business rules. Fatigue Assessments can be stored for comparison with the IFLS data for analysis and improvement of the settings. All data can easily be emailed.
If fatigue could be a safety risk in the work environment, Fatigue Predictor is the tool to mitigate this risk. It is simple to use and it can be used remotely on all Apple IOS devices. It will provide a very accurate prediction of your fatigue and is very adaptable.
