meet rox, the app behind these trackers
these trackers are free and work right here in your browser. rox is the app behind them, and it does the part a browser cannot: it remembers every day you log, pulls in your apple watch, oura, garmin or amazfit, and shows you the patterns behind your worst weeks.
each one is free and works in your browser. no sign-up required.
symptom tracker
log which symptoms showed up, how strong each one was from 0 to 10, and what was going on that day. builds a 14-day pattern view so you can see what is actually getting worse.
available now
mood tracker
track how you are feeling emotionally next to sleep, energy and symptoms, because with chronic illness those move together far more often than people expect.
available now
medication tracker
keep doses, timing, missed days and side effects in one place, and build a clean medication list you can hand to a doctor or pharmacist.
available now
pain tracker
record where it hurts, how intense it is, what kind of pain it is, and what helped. includes a 0 to 10 pain scale you can use in appointments.
available now
flare tracker
log when a flare started, what might have set it off, how much it limited you, how long recovery took and what actually helped you through it.
available now
trigger tracker
line symptom spikes up against sleep, stress, food, exertion, weather, hormones and travel to find what keeps showing up before a bad stretch.
available now
fatigue tracker
follow energy, exertion, rest and crashes so pacing becomes something you can see rather than guess at. built with pem and post-exertional crashes in mind.
available now
sleep tracker
log when you slept, how broken it was, and what the next day felt like, so you can see how much of tomorrow symptoms start the night before.
available now
food symptom tracker
connect meals and drinks with symptom timing. useful for gastroparesis, mcas and ibs, where the gap between eating and reacting is the whole story.
available now
treatment tracker
note what you tried, the dose, when you started, what changed and what it cost you in side effects, so did this help has an actual answer.
available now
symptoms that move
when things change day to day and memory cannot be trusted, a log is the only reliable record.
getting taken seriously
walking into an appointment with weeks of data changes the conversation from how have you been into something concrete.
finding your triggers
if you suspect something sets you off, tracking is how you prove it instead of guessing.
1
pick two or three things you actually care about, not everything at once
2
log at the same time each day so entries stay comparable
3
give it two to three weeks before you read anything into it
4
bring the summary to your next appointment
everything you log here lives on this device only. rox carries it further: your full history in one place, your apple watch, oura, garmin or amazfit data alongside it, and months of logs turned into a summary you can actually hand to a doctor.
01
what is the best chronic illness tracker?
the best tracker is the one that matches how your condition actually behaves and that you will keep using. three things matter: you should be able to log symptoms and severity in under a minute, it should surface patterns across weeks instead of just storing entries, and it should sit alongside the rest of your health data. rox covers all three. it is free, built specifically for chronic illness rather than general wellness, and it connects with apple watch, oura, garmin and amazfit so your symptom logs sit beside your sleep, heart rate and activity.
02
what is the best chronic illness app?
most health apps are built around fitness goals, which treats a bad day as a failure rather than information. rox is built for chronic illness, where the useful question is why some weeks are worse than others. it is free, tracks symptoms, fatigue, flares and medication in one place, connects with apple watch, oura, garmin and amazfit, and turns months of logs into a summary you can bring to an appointment. the honest caveat: rox is iphone only at the moment, so on android the browser trackers on this page are your best free option for now.
03
what is the best free symptom tracker app?
rox is free, with no paywall on symptom tracking. many trackers let you log for a week and then ask for a subscription before showing you any patterns, which is the exact point where tracking starts to be useful. rox keeps symptom logging, pattern views and wearable syncing free. if you would rather not install anything, the symptom tracker on this page runs in your browser with no sign-up at all.
04
is there an app that connects my oura ring or garmin to my symptoms?
yes, and it is the main reason people move to rox. an oura ring or garmin watch can tell you your hrv dropped and your sleep was broken. it cannot tell you your joints hurt or that brain fog took your afternoon. rox puts both on one timeline, so you can see whether the night your readiness fell was also the night before a flare. it connects with apple watch, oura, garmin and amazfit.
05
how often should i track my symptoms?
once a day is enough for most people, ideally around the same time so entries stay comparable. tracking several times a day tends to produce more data and less insight, and it burns the energy you were trying to protect. the exception is flares, where logging at the start and the end helps you see how long recovery actually takes.
06
can i show my tracker to my doctor?
yes, and it is one of the most useful things you can bring. a short summary of the last few weeks, with your worst symptoms and how often they hit, is far more useful in a ten minute appointment than trying to recall it. every tracker here lets you copy or email your log, and rox can turn a longer history into a doctor ready summary.
07
is my tracking data private?
the trackers on this page save only in your own browser, on your own device. nothing is uploaded and there is no account to create. clearing your browser data clears your log, which is the trade-off for keeping it entirely on your side.
what is worth tracking changes a lot depending on what you are living with.
rox helps you track and understand your symptoms. it is not medical advice, and it cannot diagnose or treat anything. if something feels urgent, contact a health professional.
