Apex Health: Sleep & Recovery is a general wellness and fitness app. It is not a medical device, it cannot diagnose or monitor any condition, and nothing it shows you is medical advice. Read this page before you make any decision about your health based on what the app displays.

1. What the app is

Apex Health: Sleep & Recovery is a free app for iPhone and Apple Watch, published by Truestep Solutions. With your permission it reads data you have already recorded in Apple Health, computes general wellness and fitness information from it on your device, and presents that back to you as scores, trends and a daily verdict.

It is designed to help you notice patterns in your own training, sleep and daily habits. It is a mirror held up to data you already have. It is not a clinical tool, and it is not qualified to tell you anything about your health in a medical sense.

2. Not a medical device

The app is not a medical device. It has not been evaluated, cleared, approved or certified by any medicines or medical device regulator, in India or anywhere else. It is not intended to diagnose, treat, cure, mitigate or prevent any disease or medical condition.

Do not use the app to make a medical decision. Do not use it to decide whether to start, stop or change a medicine, a treatment, a dose or a therapy. Those decisions belong to you and a qualified health professional who knows your history.

3. How the scores are produced

Strain, Recovery, Sleep, Stress and Energy are estimates. Each one is calculated on your device from the Apple Health data you have chosen to share, using transparent heuristics: published, commonly used formulas and rules of thumb from sports science and general wellness practice, applied to numbers like heart rate, heart rate variability, sleep duration and stages, and activity.

• They are model outputs, not measurements. Nothing in the app measures a physiological state directly.
• They are not medical measurements, not clinical scores, and not validated against any clinical standard.
• They are most useful as a trend over weeks, compared against your own history, and least useful as a single number read on a single morning.
• A number can look poor when you feel fine, and can look excellent when you do not. How you actually feel is better evidence than a score.

4. What the app does not do

To be completely plain about the limits:

• The app does not detect any medical condition.
• The app does not diagnose any medical condition.
• The app does not monitor any medical condition, and it must not be relied on to watch over one.
• The app does not detect a heart attack, a stroke, an arrhythmia, sleep apnoea, an infection, a metabolic disorder or any other illness, and it will not alert you to one.
• The absence of a warning in the app means nothing at all about your health. The app has no warnings of that kind to give.

5. Why readings vary

The app can only be as good as the data it is given, and that data varies for ordinary reasons:

• How a wearable is worn. A watch worn too loosely or too tightly, worn over a tattoo or high on the wrist, or moving during exercise, produces less reliable heart rate and heart rate variability data.
• Illness. An infection, a fever or a recent vaccination can move your resting heart rate and variability for days, which will change what the app shows.
• Medication. Many common medicines, including beta blockers, stimulants, antihistamines and sleep aids, affect heart rate, sleep architecture and the readings derived from them.
• Data gaps. A night without the watch, a flat battery, a permission you have not granted, a manual entry, or a device that has not synced will leave holes, and a score computed over a gap is less trustworthy.
• Everything else. Alcohol, caffeine, altitude, heat, dehydration, travel across time zones, stress and age all move these numbers.

Treat an unusual reading as a prompt to pay attention, not as a finding.

6. Talk to a qualified health professional

Consult a doctor or another qualified health professional about any question or concern you have regarding your health, before beginning or significantly changing an exercise programme, and before acting on anything the app suggests. This is particularly important if you have a symptom that worries you, such as chest pain, breathlessness, fainting, palpitations, or persistent exhaustion.

Never disregard professional medical advice, and never delay seeking it, because of something you saw in this app. A reassuring score is not a reason to wait.

7. In an emergency

The app is not an emergency service and cannot summon help. If you think you are having a medical emergency, stop using the app and contact your local emergency services immediately, or go to the nearest emergency department. In India, call 112. Elsewhere, call the emergency number for the country you are in.

Do not wait to see what the app says, and do not use it to decide whether an emergency is real.

8. Not a substitute for your device or your clinician

Your iPhone and Apple Watch include their own health and safety features, provided and regulated by Apple, such as ECG, irregular rhythm and high or low heart rate notifications, fall detection and emergency calling. This app is separate from all of them. It does not replace them, does not extend them, and does not act on them. Keep them switched on and follow what Apple tells you about them.

Equally, the app does not replace a clinician. It has no access to your history, your examination, your test results or your context, and it cannot exercise judgement about you.

9. Pregnancy, diagnosed conditions and medical supervision

Some people should treat the app as informational only, and should not use its numbers to guide training, rest or anything else without a professional's input. That includes you if you are pregnant or recently gave birth, if you have a diagnosed cardiac condition such as arrhythmia, heart failure or hypertension under treatment, if you have a diagnosed sleep disorder such as sleep apnoea, insomnia or narcolepsy, if you are under medical supervision for any condition, or if you are recovering from surgery, injury or serious illness.

In these situations the app's models are outside the range of ordinary healthy adults that they assume, and their output can be misleading. Follow your care plan and your clinician, and use the app, if at all, only as a diary of numbers you already collect.

10. Age

The app is not intended for use by anyone under 16. The scores it computes assume an adult, and it is designed for adults managing their own health and fitness. If you are under 16, please do not use it.

11. Related documents

This disclaimer sits alongside the other documents for the app. The Privacy Policy explains what data the app touches and where it stays, which is on your device. The Terms of Service set out the licence, the warranties and the limits of our liability, and this disclaimer forms part of them. If you have a question about how something works, Support is the place to start.

12. Changes to this disclaimer

We will update this page if the app changes in a way that affects what is written here, and the date at the top will show the current version. One thing will not change: this app is a wellness tool, and it will not become a medical device without being properly regulated as one first.
