this tracker lives on this device only. rox keeps every day you log, reads your apple watch, oura, garmin or amazfit, and lines your energy up against your sleep and activity.
how it works
1
rate how heavy the fatigue felt from 0 to 10
2
tap what you spent energy on and how your body answered
3
come back daily and your pacing pattern appears
your data stays on this device. we never see it, and there is no sign-up.
01
how do i track fatigue properly?
rate it once a day at a similar time, and log what you actually did alongside it. fatigue on its own is just a number; fatigue next to what you spent energy on is what shows you your ceiling. for post-exertional malaise, the important part is logging the day after exertion, not only the day of it.
02
what is pacing?
pacing means staying inside your energy limit rather than pushing to it and crashing. the hard part is knowing where the limit is, which is exactly what a log tells you: after a few weeks you can see which activities reliably precede a crash, and how much rest you actually need to recover.
03
what is the best fatigue tracker app?
the one that takes seconds on a bad day. this tracker is free and needs no sign-up. rox is the free ios app version: it keeps your full history and puts your fatigue next to your heart rate, sleep and activity from your apple watch, oura, garmin or amazfit.
04
can this help with me/cfs or long covid?
it can help you see patterns, which is the first step in pacing, but it cannot diagnose anything or replace clinical advice. if you experience post-exertional malaise, log the day after activity too, since that is usually where the cost shows up.
05
is my fatigue data private?
it saves only in your own browser, on the device you are using. nothing is uploaded and there is no account to create.
rox helps you track and understand your health. it is not medical advice and cannot diagnose or treat anything. if something feels urgent, contact a health professional.
