Chroma is a health tracker designed for people living with chronic and invisible illness — where your pain, mood, and symptoms become a living colour map of how you actually feel.
You can't always describe pain in words. You can't always remember how you felt last Tuesday. And you can't always make it to the doctor. Chroma holds it all for you — silently, consistently, beautifully.
SDAM, fibro fog, and medication side effects make it nearly impossible to recall symptoms accurately at appointments. Chroma remembers for you.
When "it hurts" isn't enough and you can't find the words, a colour-coded body map communicates what language can't.
Chroma turns months of daily logs into a clean medical summary — ready for your pain specialist, GP, or surgeon before every appointment.
Mood, pain, energy — tap an emoji, slide a bar. Tap your body where it hurts. Takes twenty seconds. No wrong answers.
Over days and weeks, Chroma builds a picture. Your Samsung watch data syncs automatically — sleep, heart rate, HRV, stress — filling in the gaps.
Before any appointment, tap Export. Chroma generates a plain-English medical summary — with your body map, patterns, and medication history — ready to hand over.
Front and back views with 40+ selectable regions. Each one fills with a colour that corresponds to your pain intensity — from pale yellow through orange to deep red.
Over time, the regions that light up most tell your story to doctors better than words ever could.
Tap an emoji for mood. Slide for pain and energy. Done. No forms, no pressure — twenty seconds on your worst day.
Tick off meds daily. Running low? Chroma alerts you — and your carer — with enough time to reorder before you run out.
Log upcoming appointments and get reminders. Before each one, generate a pre-appointment summary so you don't have to remember a thing.
7, 30, and 90 day views of your mood, pain, and energy trends. See which days are hardest, and how your watch data correlates.
Before any appointment, tap Export. Chroma pulls together everything you've logged — pain locations, mood trends, medication history, watch data — and writes a plain-English summary ready to hand to your specialist. No preparation required. You show up. Chroma has done the rest.
Your Samsung watch tracks heart rate, HRV, sleep stages, and stress — even when you're too exhausted to notice how bad a day is. Chroma pulls that data automatically and shows you the patterns.
Low HRV often correlates with high pain days. Poor sleep precedes flares. Chroma surfaces these connections so you and your doctor can see them too.
Pattern detected: On days your HRV was below 30ms, your pain score averaged 3.8/4. Today your HRV is 24ms — this may be a difficult day.
No complicated setup. No subscription required to start. Just open Chroma on your phone, and begin.
