Adam Sensor

Track your night-time erections at home, while you sleep

See how often your night-time erections happen, how long they last and how your patterns change over time, with a small wearable and the free Adam Health app.

• At home and private. Wear it while you sleep and see your results in the app in the morning.
• Comfortable to wear. Weighs about 20 g, with an adjustable, non-constricting band.
• Clear results. Erection episodes, total duration and a quality score against your own baseline, plus trends over time.
• Your AndroAge™ score. A personal benchmark, in years, once you’ve recorded three valid nights.
• No subscription. The app is included, with no monthly charge.
• 2-year warranty. Plus a full refund if it doesn’t fit, and support from the Adam Health team.

The Adam Sensor is a small, rechargeable wearable that tracks night-time erections while you sleep. It is worn at the base of the penis and works with the Adam Health app to display recordings, personal insights and trends over time.

It is a general wellness product, not a medical device. Its results are intended to help you understand your own patterns and should not be used to diagnose a condition or make treatment decisions.

Why night-time erections matter

On average, men experience 3–5 erections every night, while they sleep. This is your body’s built-in maintenance routine.

Your body’s natural night gym

Each episode sends oxygen-rich blood into the erectile tissue, keeping it flexible, nourished and healthy — like a nightly workout that protects function for the long term. Just as your daily steps reflect physical activity, the total duration of your night-time erections reflects how well your body is maintaining itself at rest. Longer total duration means better oxygenation, tissue health and recovery.

A key indicator of male longevity & wellness

Night-time erections are more than a measure of performance; they are one of the most powerful functional biomarkers of men’s health. They depend on your cardiovascular system, hormones, nerves and sleep quality. Changes in night-time erections often mirror early shifts in heart, metabolic or hormonal health long before symptoms appear. Through the Adam App this is translated into your AndroAge™ — a single score, expressed in years, that reflects how well your body is functioning across these systems.

The Adam Sensor

The Adam Sensor records changes in penile circumference during the night. Most men will experience a number of erections while they sleep. The number and quality of these erections can be used to track your blood flow and overall health.

Recordings taken by the Adam Sensor are transferred to the Adam Health app using Bluetooth, where they are analysed and presented as:

• The number, timing and duration of recorded erection episodes.
• The total recorded erection duration.
• An erection quality score measured against your own baseline.
• The length of the recording.
• Trends over time.
• An AndroAge™ wellness score once enough valid measurements have been collected.

AndroAge™ is Adam Health’s wellness score, expressed in years. It compares your recorded night-time erection patterns with average patterns across age groups. It is a personal benchmark for tracking changes over time, rather than a medical or biological age.

The Sensor has an adjustable, retractable band designed to accommodate changes in size without constriction. It weighs approximately 20g and charges using the supplied USB-C cable. A full charge takes about an hour, and gives up to 14 hours of recording. 

The app is available for iOS and Android. 

How it works

1. Charge it. A full charge with the supplied USB-C cable takes about an hour.
2. Download the app. Get the free Adam Health app on iOS or Android and pair the Sensor over Bluetooth.
3. Put it on before bed. The Adam Sensor sits at the base of the penis with an adjustable, non-constricting band.
4. Sleep as normal. Your results are in the app in the morning. After three nights you’ll have your AndroAge™ baseline. After that, once a week or every couple of weeks is enough to follow your trend.

Warnings

• Not for diagnosis or treatment. The Sensor and app are not intended to diagnose, treat, cure or prevent any disease or condition. Results are wellness measurements, not diagnostic test results.
• Do not use results to change medication or treatment. If you have health concerns, speak to a qualified healthcare professional.
• Follow the fitting instructions. Use the supplied guide and in-app instructions. If the Sensor is uncomfortable or does not fit properly, stop using it and contact Adam Health.
• Keep the Sensor dry. The Adam Sensor is not waterproof or water-resistant. Do not immerse it in water or allow liquid to enter the charging port or switch. After accidental liquid exposure, stop use and contact Adam Health before using or charging it again.
• Use during sleep only. Do not wear the Sensor during sexual activity.
• Consider trends over time. Recordings may vary with sleep, stress and lifestyle. A single night’s result should not be used to draw conclusions about your health.
• Get medical help if you need it. If you have pain, injury or other urgent symptoms, stop using the Sensor and seek medical advice straight away. Don’t wait for a reply from product support.

Delivery

The Adam Sensor is provided through Adam Health. Orders will be dispatched within 2 business days of purchase, and will be sent as a tracked standard delivery.

Will I feel it while I sleep?

The Sensor weighs about 20 g and uses a flexible, adjustable band rather than tight elastic or a rigid ring. It’s designed to stay in place through the night without applying pressure.

How is it different from a penis ring?

Most rings are designed to constrict. The Adam Sensor isn’t: it’s designed to be worn overnight to record, with a non-constricting band that doesn’t restrict blood flow or natural movement.

Is my data private?

Your data is encrypted and used only to provide your insights in the app. Adam Health does not sell your personal health information to third parties, insurers or advertisers.

How is the Sensor worn, and will it fit?

It is worn at the base of the penis before sleep. The adjustable band is non-constrictive and designed to accommodate changes in size.

Follow the supplied guide and in-app fitting instructions. If it is uncomfortable, does not fit securely or repeatedly falls off, contact Adam Health for support. 

If it doesn’t fit, Adam Health offers a full refund.

How is it charged, and how long does the battery last?

The Adam Sensor is charged using the supplied USB-C cable. Follow the provided charging instructions. A red light indicates charging and turns off when the Sensor is fully charged. The battery is designed to last a full night, with up to 14 hours of recording on a full charge.

Do I need a smartphone?

Yes. The Adam Health app is needed to set up the Sensor, manage recordings and view results. The app is available for iOS and Android. Adam Health can confirm compatibility with a particular phone.

Does the phone need to stay connected all night?

No. Once recording is underway, the Sensor can continue recording if the phone disconnects or is switched off. Reconnect it to the app in the morning to transfer the recording, following the current in-app instructions.

How often should it be used?

Adam Health recommends three initial nights of recording to establish a baseline. At least three valid measurements are needed for initial AndroAge™ insights.

After that, you can use it weekly or fortnightly to track trends.

Why might results vary from night to night?

Sleep, stress and lifestyle can affect recordings. The aim is to understand patterns over time.

If you have any questions about recordings or app results, please contact Adam Health. If you have concerns about what the results might mean for your health, please speak to your GP or another healthcare professional.

Can it diagnose erectile dysfunction or another health condition?

No. The Adam Sensor is a general wellness tracker. Neither its recordings nor its AndroAge™ score can establish or rule out a medical diagnosis.

Is there a monthly subscription?

Your purchase includes access to the app with no monthly charge. 

Who should I contact for product support?

Adam Health handles fitting, setup, app support, recording and results queries, faults, warranty, product returns and product complaints.
