Your symptom & mood tracker. In one tap.

It really is one tap.

Tap a symptom to log it. Keep tapping to raise the severity. Tap it again later, once it's gone. Five seconds a day, with no forms to fill in.

Track your mood. See what lifts it.

Once a day, Trace Health asks how you felt overall. One tap, plus a private note if you like. After a few weeks it shows what tends to lift your mood and what weighs on it, from sleep, caffeine and alcohol to exercise and medication, and how your mood moves around your symptoms.

How mood tracking works in Trace Health

Know what your cycle brings, before it comes.

Your period, your symptoms, your mood

Log your period in one tap, like any symptom. Trace Health follows your cycle: the day you're on, your usual cycle and period length, and when your next period should come. After a few cycles it shows which symptoms get worse the week before your period, as it starts or around ovulation, and tells you what to expect in the days ahead.

• Cycle Calendar with your next periods and fertile window
• Brings in your periods from Apple Health or your period app
• Made for PMS, PMDD, endometriosis, PCOS and perimenopause
• On Apple Watch and in a Home Screen widget: your cycle day on a ring (Premium)

Why your cycle matters, and how Trace Health tracks it

Log from your wrist.

Symptoms don't wait until your phone is in your hand. Raise your wrist and tap: on a walk, in a meeting, or in bed in the dark, when a bright screen is the last thing you want. Everything lands on your iPhone, in the same history, charts and reports.

On your watch face

All your symptoms

Your week at a glance

Your mood

Your cycle

Activities too

Syncs with your iPhone directly: no account, no server of ours. Needs watchOS 11 or later and Trace Health on your iPhone.

“Coffee is why you can't sleep.”

Log the ordinary stuff: coffee, late nights, workouts, meds. Trace Health lines it up against your symptoms and your mood, and tells you when the effect lands, how likely it is, and exactly which logs it's based on.

Trace Health starts telling you things.

See how it evolves

A clear view of how your health moves over weeks, months and years. The Insights tab turns your symptom tracking into trends, week-on-week comparisons and a Year in Pixels, then says in plain language whether things are actually getting better.

It connects to the rest of your life.

Syncs both ways with Apple Health

Every other tracker we know of only reads from Apple Health. Trace Health writes to it too: your symptoms become real Health entries, next to sleep and cycle. And it reads back what Health already knows, so you never log it twice. To Apple Health: Symptoms, activities and mood. From Apple Health: Workouts, sleep, mood and periods.

Track the whole family

Separate profiles for a partner, a child, an ageing parent. Switch between them in a tap; each keeps its own symptoms, history and reports, on the same phone, still with no account.

Hand your doctor a PDF

One button turns your tracking into a clean report for your doctor or specialist: severity across the dates you pick, each symptom's Year in Pixels, its episodes (how long they last, how bad they get) and the activities you logged. Made to get the most out of the time you have in the appointment.

Log your symptoms without opening the app, with Widgets

Widgets put any symptom one tap away on your Home Screen, next to today's mood and your cycle day. Live Activities keep the ones you have active on your Lock Screen, where you can see them and change severity without opening the app.

Your symptoms, your setup.

Start from 34 conditions, 100+ symptoms across 12 categories, from neurology and gut health to dermatology, women's health, mental health, sleep and heart. Keep the ones you actually live with, reorder them, hide the rest.

On Premium, add your own with your own name, colour and icon, so the app is shaped around your condition instead of an average of everyone's.

Your health data never leaves your iPhone.

No account to create. No private health data on a server, because there is no server. No ads, nothing sold. Delete the app and the data goes with it.

What people say

Rated 4.8 out of 5 from 62+ ratings on the App Store.

• A perfect app for tracking symptoms, “About a month ago, I did a scan of the App Store to see if there was any new apps for symptom tracking and I found Trace Health. It had what I was looking for, but missing some minor features. I decided to give it a shot and I was really pleased with it, it worked in the way I wanted it. And the biggest plus was a super dedicated developer that keeps adding features that I was wondering about at a super fast pace. I can’t recommend Trace Health high enough!!!” (redferret2001, United States)
• Useful, “This is what I was looking for in a symptom tracking app. I like the ability to adjust severity and check in when a symptom has resolved itself.” (Missyfro, United States)
• Game changer, “I’ve only used this app for a few minutes, but I already know it’s going to be amazing. I’d been looking for a long time for something practical to monitor the symptoms of my chronic illness. The basic need is already met, and if the analysis feature works as planned on top of that, it’ll be just extraordinary.” (Maud'moiselle, France)
• Really good and simple symptom tracker, “I’m really happy with Trace. It makes it easy and quick to record symptoms, pain and how they change over time, without it becoming a hassle or hard to keep up with. The app is intuitive and clear, and I especially like being able to get a better overview of how my symptoms are developing. An app I actually end up using day to day. ⭐️⭐️⭐️⭐️⭐️” (LilandAndreas, Denmark)
• Chronic conditions must have!, “Absolutely love, love, love. Exactly what I needed to track my symptoms. LOVE it doesn’t collect data and syncs with apple health. I want to log to apple health, but it is cumbersome. This solves that and then some!” (alouusea, Iceland)
• This is a game changer, “Ok so I try so hard to track symptoms but apple health doesn’t have a widget for that and it’s kind of a pain to track down every little thing… Now this app!!!! Everything is right there, there’s widgets, it’s fast and simple and syncs! I freaking love this app! I’m still playing with it so I haven’t seen if it has a “how are you feeling right now” feature but it is everything I have ever wanted the symptoms on health to be!” (grofica82, United States)
• My health, “This has given me a great tool to discuss my health issues with my doctor” (WVa Smitty, United States)
• Super!, “Very clean and well organized, nicely customizable. Practical widgets for the home screen. Exactly what I was looking for, thanks 👍” (jxleya, Germany)
• The app I was looking for, “I highly recommend this app, no annoying ads etc, straight to the point of keeping a track of health symptoms, the best health monitor app I have ever used.” (Trisroy-Best, United Kingdom)
• Very useful and private, “The app is simple, fun, and life-changing for me. I chose it mainly so that my data is never shared, and because it’s the easiest to use. I used to write my symptoms down in a notebook; now I do it every day on the app to track how they change. Being able to also log my everyday activities to see their influence is very handy. I recommend it!” (Solex94, France)
• Exactly what I was looking for, “Out of all the symptom tracker apps, I found this to be the easiest and most straightforward. It “writes” to the health app, which is exactly what I wanted. All the others only “read” parts of the health app data, and didn’t truly write any data back. This helps me visualize my chronic symptoms soooo well.” (EB1700, United States)
• Simple and useful, “I’m not really into tracking mood and habits but this app has shown me the benefit of doing so and has helped me reflect on my day to help find the positives and see where I can improve.” (GavinLanoe, United Kingdom)
• Very useful, “This app is wonderful. You can add symptoms and rearrange them as you like. The best part: your sensitive health data is only stored on your own device.” (WhoKnowsTypo, Netherlands)
• Great app, “Finally a simple iOS 26 symptom reporting app, thank you 😀” (stranack, United Kingdom)
• Top-notch, “Finally an app in which I can collect and analyse all my symptoms. And that reminds me to log them.” (sunsoul01, Austria)
