Patterns require repetition
Actions need multiple attempts before a possible pattern appears.

See What Helps Me
Possible patterns appear after repeated attempts—not one data point.
One attempt never becomes a pattern.
What Helps Me
Evidence, not guesswork.
Cortisol Aware learns from your repeated check-ins, not a single moment. “Still learning” means the app needs more of your own data.

Cortisol is real. A watch reading is not.
Cortisol is an essential hormone. It supports the stress response, metabolism, blood pressure, and inflammation. Levels usually run higher in the morning and lower later in the day.

General wellness context
Sleep, HRV, heart rate, and activity
Context is not a cortisol result.
The essential limit
Cortisol Aware is an educational wellness tool. It does not measure or estimate cortisol, diagnose a condition, recommend treatment, or replace laboratory testing, a health professional, or emergency care.
Focus on what you can observe. Leave room for real life.
Cortisol control is not the promise. A calmer, more informed routine is the focus.
Sleep rhythm
A regular schedule and a quieter, dimmer hour before bed can support healthy sleep habits.
Light & time outdoors
Light and darkness are major cues for the body’s circadian system.
Movement
Even small amounts of activity can be a useful place to begin, based on your abilities.
Eating pattern
Meal timing and caffeine can affect sleep context. No food or schedule “balances” cortisol.
Relaxation
Slow breathing and focused attention may feel calming. They do not replace care.
Build routines that leave more room for the day—and the people—you care about.
Medical terms deserve medical context.
Daily stress is not a diagnosis. The conditions below require qualified clinical evaluation and standard tests.
Cushing’s syndrome
A clinician-diagnosed disorder caused by exposure to too much cortisol over a long period. Long-term, high-dose glucocorticoid medicines are a common cause; some tumors can also cause the body to make too much cortisol.
Cushing’s disease is the subset caused by a pituitary tumor that makes too much ACTH.
NIDDK: Cushing’s syndromeAdrenal insufficiency
A clinician-diagnosed condition in which the body does not make enough cortisol. Addison’s disease is primary adrenal insufficiency caused by damage to the adrenal glands.
Symptoms can overlap with many other problems. An app or symptom list cannot diagnose it.
Endocrine Society: Adrenal insufficiency“Adrenal fatigue”
“Adrenal fatigue” is not a scientifically established medical diagnosis, and there is no validated test for it.
Ongoing fatigue, weakness, sleep problems, or low mood deserve an appropriate clinical evaluation.
Endocrine Society: Adrenal fatigue
Prescription steroid safety
Do not stop or change prescription corticosteroid or glucocorticoid medicine based on this website or app. Talk with the clinician who prescribed it.
Get emergency help now
Adrenal crisis is a medical emergency. If you have diagnosed adrenal insufficiency and develop severe vomiting or diarrhea, cannot keep your prescribed corticosteroid medicine down, or have severe weakness, dehydration, abdominal pain, confusion, fainting, or very low blood pressure, follow your clinician’s emergency plan and seek immediate medical attention. Call your local emergency number.

Frequently asked questions.
Does Cortisol Aware measure cortisol?
No. Cortisol Aware and Apple Watch do not measure or estimate cortisol. Clinical cortisol testing uses a biological sample such as blood, urine, or saliva.
Can the app diagnose a condition?
No. It cannot diagnose stress, Cushing’s syndrome, adrenal insufficiency, insomnia, anxiety, “adrenal fatigue,” or any other condition. It offers general wellness context only.
What can Apple Health tell me?
With permission, the app can compare selected observations such as sleep, heart rate, HRV, and activity with your own recent history. Each signal has many possible influences.
When should I speak with a clinician?
If fatigue, weakness, weight change, sleep difficulty, or other symptoms are persistent, worsening, or concerning, contact a qualified health professional. These symptoms have many possible causes.
Where is my health data processed?
Raw HealthKit data stays on your device by default. The app uses read-only access for the data types you choose and does not require an account.
