Comments on ReadiOne by Fatigue Science for Android

★★★★★ Sean Kerklaan · Jun 28, 2018
In depth insights into what my sleep quality and sleep consistency are and how the cumulative effects impact my performance and my safety risk
★☆☆☆☆ Ryan Marlow · Apr 23, 2020
Synced with Readi band 5 ok for 3 days and then just stopped syncing. Have tried to uninstall and reinstall app. Sync/refresh symbol in app also 'greyed' out.
★☆☆☆☆ Matthew Johnson · Apr 2, 2020
Will not sync to ReadiBand5 anymore. I've setup and used 2 bands and they both quickly failed to sync after just a few days. Second band only synced twice before failing. Followed all the troubleshooting steps. Nothing fixes the issue once it stops syncing. It's been over 10 days since it last synced. The software seems to have compatability issues or bugs. There is no way to force syncing as the software can't locate the band, using the options menus button.
★★☆☆☆ Anthony Brayshaw · Aug 2, 2020
Have issues with syncing if I miss syncing just after 12-18 hours it won't syns and resets to 3 and can't locate device can be a pain in the ass. Tech support is good tho any issues I have usually are sorted out quickly. I have to rely on the device for my work to be able to do over time shifts. Would like to see major upgrades to this app to sort out these issues. It makes it a pain when I have to travel for work and because it won't sync i don't a score and miss out on overtime.

Description by Sleep Performance, Inc. Written by the developer, not by AppBrain. Click to read.
Any disruption to your normal sleep, whether from sleep loss, jet lag or night duty, can significantly impact your ability to perform safely and effectively -- whether you're on duty in a dangerous job, and on the field as an athlete. Specifically, sleep impacts your cognitive performance and your reaction time. ReadiOne uses a proprietary biomathematical model to analyze your sleep in order to quantify and predict the impact it will have on your performance for the day ahead.

When you wake up, sync your sleep from your Fatigue Science ReadiBand or your Fitbit, and you'll receive a personal risk assessment ("ReadiScore") for each of the 18 hours ahead, enabling you to easily visualize if and when you'll be at your best and worst in the day ahead. You'll also be able to track daily improvements to your readiness over time, and you'll receive alerts before your fatigue may reach critical levels. ReadiOne is based on validated algorithms developed with 25 years of sleep research from the US Army Research Lab, and available exclusively from Fatigue Science.

ReadiOne is designed for the end-users of the Readi enterprise fatigue management platform.
