Even: Stress Tracker & Relief
HRV, Sleep & Burnout Monitor
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
New: read before bed by the fire, keep a postcard from every walk, and let the workouts you log elsewhere count toward your day.
Most stress apps tell you how you are doing. Even tells you what to do about it, then shows you whether it worked.
IT STARTS BY READING THE LAST NINETY DAYS
Even reads what your iPhone has already recorded: sleep, heart rate, heart rate variability, resting heart rate, wrist temperature, breathing rate, activity, cycle tracking and State of Mind from Apple Health. Then a short set of questions about your weeks, your nights, and what you carry.
Even opens by playing back the season you have just lived: what it cost you, where it landed, when it peaked, and a name for the stretch you have been in.
ONE NUMBER EVERY MORNING
The Even score runs 0 to 100, higher meaning more even, in five bands: Spent, Stretched, Steady, Light, Bright. It weighs five things, each read against your own history rather than a population average: sleep, body at rest, the day's demand, mood, and activity balance.
Under it, a Foundations layer checks the absolutes a relative score is not allowed to flatter, like a seven hour sleep floor and how regular your nights are. A chronic short sleeper is never told there is nothing to work on.
Each morning also gives you one line on how to pace the day.
THEN SOMETHING TO DO ABOUT IT
Three suggestions a day, sized to the score and the hour. Paced breathing with haptics on the breath. Nature sounds recorded outdoors. Ambient songs. An evening wind-down that ends with the screen off. A walk counted by your own steps, kept as a postcard. Journaling, with one question from your own day or a blank page, and a photo or a video. Reading before bed, in a quiet room by the fire. A second look at a thought, written on device with Apple Intelligence. A quick movement burst. Guided stretching, standing or floor.
AND PROOF THAT IT WORKED
This is the part most apps skip. After each session Even reads what your heart did and takes one tap on how you felt. Over a few weeks it ranks the sessions by what worked for you, so you stop guessing and spend your effort on what settles you. Sessions file back to Apple Health as mindful minutes and workouts.
Trends lays out what your data holds, today and over time.
Every sentence Even shows you traces to a number it computed. The research is cited in the app by name and DOI, including the Harvard and Michigan work the model is designed on.
WHAT EVEN WILL NOT DO
It is not a medical device. It does not diagnose, treat, prevent or cure anything, and will never tell you that you have a condition.
It will not shame you. Nothing in it is designed to make you feel bad for not opening it.
No ads.
It will not guess at a number it does not have.
WHAT YOU NEED
An iPhone, and Apple Health with some history in it. The more nights it holds, the sooner Even can read you. Even works best with physio data from a wearable.
A subscription. Even is not free and has no free tier. The yearly plan includes a one week free trial, so you can see the whole app before you are charged.
An account, created after purchase with Sign in with Apple or Google, so your readings survive a new phone. What syncs is derived: scores, check-ins, session outcomes. Never a raw Health sample. You can delete your account and everything in it from inside the app.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Read before bed. A quiet room by the fire, music for the first twenty minutes, and a line from your book to keep.
A walk keeps a postcard: your whole photo, the steps and the distance. Fitness gets the distance too.
A journal page can keep a photo or a short video.
A hike, a yoga class or a meditation you log in another app now counts toward your day.
Sessions end on a short sheet. Once Even knows how a session lands for you, it stops asking every time.
Hold anything in your diary to delete it.
