Hanu is the first of its kind, complete stress resilience and cognitive performance platform. We use incredibly accurate data to help you measure, analyze and resolve stress, improve cognitive performance and feel better.

Every metric we track is linked to stress and is always interpreted in that context. We currently track:

1. Heart Rate Variability: As we become stressed, HRV will be reduced.

2. Heart Rate: As we become stressed, HR will increase.

3. Respiration Rate: As we become stressed, respiration rate can increase or decrease (breath holding).

4. Movement: The more we move, the better we enhance resiliency to stress. 

Heart Rate Variability (HRV) is the single greatest, non-invasive metric for measuring changes in the human stress response. While Heart Rate (HR) looks at the average number of heart beats that occurred in one minute, HRV (namely RMSSD-Hanu’s predominate metric of the relaxation response) is a metric of the amount of time that occurred between adjacent heart beats. This is important because as we become more relaxed, we activate our parasympathetic nervous system and this results in an increase in HRV. While this is a VERY simplified understanding of HRV, check out this article for a deep dive!

Unlike some wearable companies that do not provide a lot of value during waking hours, Hanu is intended to be worn predominately throughout the day. Think of us as your all-day stress monitor/radar and all-day stress coach. You can monitor and train all-day, but it may be helpful to start the day with a short training.

Short answer, yes and no. Hanu is intended as a daytime device. But, if you are so inclined, you can wear your device at night and we will capture data. At this time, we are not tracking sleep stages.

We intend to support both Apple and Android but we’ll be releasing our product first on Apple and then on Android. We will update this FAQ once we have more details on the Android platform and timing.

Currently Hanu is a stand alone solution but our long term intentions are to integrate with other software and hardware platforms to give you a more complete picture of your health.

Account & Orders

We usually ship within 48 hours, sometimes sooner. As soon as we ship your Hanu you will receive a shipment confirmation email that should including your tracking number.

Once your product ships, we offer a 30 day, no questions asked, money back guarantee. For more information, please reference the Refunds area of our Terms and Conditions.

We will ask you a minimal set of questions as you onboard. We will ask you health related questions like your age, weight, biological sex, hand you will wear your device and a few other questions. We’ll use these questions to help improve your stress resilience and cognitive performance.

To edit your order information, you will be able to log into our website (coming soon) and you will be able to change your account information, billing information and more. This website will be ready in conjunction with our commercial. In the meantime, please email us if you have any questions or need anything changed.

We accept all major credit cards, Google Pay and Apple Pay. We no longer accept PayPal. If you have any questions about this, feel free to email us at help@hanuhealth.com.

App Features

Life Events is your way to log and track events that result in significant changes in your stress response. These are either prompted/generated by Hanu (we see changes in your biometrics) or they are user generated (by you). This is a great mechanism for tracking the “what” of stress. In other words, you can look back and see common themes/stressors/times that help you to improve your self-awareness. 

While we are working on becoming immensely sophisticated in our ability to determine which events are detrimental or helpful to your health, we are not there yet. That is why we want you to tell us. Only you know whether or not your experience of an event was stressful or helpful. Here is a great example: You may be in a tense discussion with a friend that is causing you stress. You might experience an increase in heart rate, reduction in heart rate variability, and increase in respiration. On the other hand, you might be having an exciting discussion with a friend that results in the same changes in biometrics. Only you would be able to tell Hanu whether or not the event caused you stress or not. 


Hanu is all about creating tailored and personalized trainings based on your goals. When we see that you have fallen outside your normal range (based on your data averages), we will alert you that it may be beneficial to practice some breathwork/biofeedback. You can view data change from start to finish and compare these changes over sessions. 

To be honest, we will not know if you are “stressed out.” We can make predictions as to whether or not your nervous system is responding in a way that indicates you might be stressed, but only you can tell whether or not you are stressed. Hanu does two thing: Creates better self-awareness and creates better self-regulation.

The single greatest method of communicating with the nervous system and instilling quick and efficient changes is with the breath.  For most people, while stressed, tuning into the breath is the quickest way of increasing resiliency to stress. Even if HRV does not change, it is still an effective means of changing your body’s response to stress. 

Hanu chose to use the most validated ECG/EKG on the market: Polar H10. There is no other device on the market that is more accurate and validated for continuous capture. Your data is accurate.

This. Is. Normal.

For many of us, we deal with performance anxiety. That is, when we are being watched or we are watching ourselves, this can impact our behavior and physiology. If you find that it is making you feel more stressed because your metrics are not moving in the direction you desire, then you can do one of three things: 

1. Toggle off your data capture in the app. Do a training session without data. 

2. Follow the pacing of your phone (vibration) without viewing data metrics during a training 

3. Focus on mindfulness of breath. This is transitioning from doing to being and tracking. Focus on the sensation of the breath, the inhale and exhale, without a focus on mechanics or biometric change.


We understand that some of you might already have a Polar H10. We only have one product offering and that is a software and hardware bundle. The hardware is a pass through expenses, meaning we sell you the device at cost and we don’t look to make any money from it. The value we add is in the interpretation of the data through our software and algorithms.

So you will receive a brand new Polar H10 with your Hanu subscription. If you already have one, having a backup is never a bad thing or you could give it to a friend or colleague. If you have any questions about this, feel free to email us at help@hanuhealth.com.

The Polar H10 is the gold standard in wireless heart rate monitoring. Plain and simple, the data that it captures is the right data. 

Simply size the Polar H10 strap to fit semi-snug, yet comfortable. The sensor the clips into the strap should be located just below the breasts and at the center of the breast place (sternum). (place picture here?)

Note: In order for the device to connect and sync with Hanu, it must be in the worn position. The Polar H10 will not connect to a device if it is off the body. 

First, you must be wearing the device in order for it to connect and sync. It requires your heartbeat in order to capture data and connect. You will NOT be able to connect to your Polar H10 if you are not wearing it.

Second, please go to the bluetooth settings of your phone. You should be able to see your Polar H10 with a status of Connected, Not Connected or in the Other Devices area. If you don’t see it, please move onto completing step three below.

Third, if you don’t see the device in your bluetooth settings, please complete a factory reset. To reset your heart rate sensor:

  1. Remove the battery.
  2. Press the metal snaps that attach to the strap with your fingers for at least 10 seconds. This will complete the circuit.
  3. Then, wait 30 seconds and then put the battery back in. Note: After the reset you need to pair the sensor with your devices again.

Fourth, if this does not work, make sure to check the battery status or try a new battery (C2025 battery).

Lastly, if all else fails, please email us at help@hanuhealth.com.

Ever get sick of having to change your device every day? Every couple of hours? Well, we solved that problem.

No charging required, at all! 

The Polar H10 uses a C2025 battery (watch battery that cost about $1.00) that lasts 400 hours of use! Again, that is 400 hours of data capture! Needless to say, you will be changing this batter quite often. But, if you need to, it is as simple as removing the old battery and placing in a brand new one. 


Waterproof up to 30M.

Absolutely. The Polar H10 was intended as a HR tracker for exercise. While our app does not track exercise performance, it may be interesting for you to continue to track HR and HRV changes during a workout. 

These things are made to be put through the ringer. We encourage you to store these in a dry and cool place, but the reality is that these devices are quite resilient. I think they have been using our app. 

Hanu Data

Pretty simple answer here, we’re using your data to help you! Everything we collect will be used to create a personalized model that we can use to evaluate your ups and downs and help you along.

We will keep all your data until you tell us to stop keeping your data. As biohackers at heart, one of the best things we can do is to give you a long term horizon view of your biometric markers as they relate to stress resiliency and cognitive performance.

But, if you ever would like us to delete your data, we will be happy to do so. Please email us at help@hanuhealth.com.

Absolutely not. We have no intentions to share your data with third parties. The only exception here will be when we partner with other software companies, you may elect to share your data. You will have to OPT IN for this to happen and we’ll make sure this is clear before that happens.
