In this review...

Picture the scene. You’ve been working on this presentation for months. Your promotion hangs in the balance, and hundreds are looking on. You have a vitally important message that you must get across but your heart is racing and you need to focus. You need Doppel to Stress Less - It’s all in the rhythm.

The transformative power of rhythm upon humans cannot be underestimated. When that rhythm is a heartbeat, something very primitive kicks in. It has long been know that a mother’s heartbeat helps the development of her unborn baby, and studies have shown this influence persists well after birth.

Rhythm is all around us, in the form of music and dance, even the way we speak.

Why does this affect us?

Your brain locks on to rhythms in your environment and follows them, through a process called ‘neural entrainment’. If you listen to a fast tempo song, your brain and body will follow this. On the other hand, a slow tempo piece will help provide calm for your body.

So it follows, we are already entrained to the rhythm of a heartbeat. And what better way to utilise this than in a convenient, and ultra discrete wearable.

Through nature’s rhythm you can regain some control over the destination of each day. A sense of control that we know is vital for living a happy and productive life.

What is Doppel?

Doppel sits on the inside of your wrist and silently vibrates, recreating the ‘lub-dub’ feeling of a heartbeat. Studies have shown slower Doppel rhythms are calming, whilst faster rhythms can help you feel focused. Doppel doesn’t distract you, allowing you to feel in control anytime and anywhere.

Researchers from the Psychology Department at Royal Holloway, University of London (2017) assessed the calming effects of doppel and found that its heartbeat-like vibration delivered onto the inside of the wrist can make the wearer feel less stressed. Our independent academic expert, Dr David Broome, was impressed with Doppel. You can read his Lab report below.

Who’s behind it?

The doppel team comprises Dr Fotini Markopoulou, Jack Hooper, Andreas Bilicki and Nell Bennett. They have spent the past four years working on technology inspired by psychophysiology - the study of the relationship between the mind and the body.

The doppel team are advised by Professor Manos Tsakiris, Professor of Psychology at the Department of Psychology, Royal Holloway, University of London.

They began working on the first prototypes in late 2013. Trials and repeated testing then followed. The initial development of doppel concluded eighteen months later with a successful kickstarter campaign. After many subsequent refinements, doppel was officially launched in 2018.

The User Lab Test

Set up. Set up is pretty straightforward with the help of the manual, which gives instructions of how to start Doppel with gesture control; press on either side of the white bar a few times and Doppel springs into life with a lub dub vibration and the mechanism in the middle spinning. The Doppel strap is adjustable by removing and replacing the popper button up and down the strap.

Easy of use. Doppel is easy to use. Once you have turned it on, you can either use it on its own or connect it to the app via Bluetooth. Once Doppel is connected to your phone, you can adjust the intensity and frequency of the lub dub vibrations as you desire.

App. The app is well made and looks good. It begins with a nice introduction and a few pages of information to scroll through on the features of Doppel. Setting up a Doppel account is similarly simple and this then allows you full access to the app and to pair your Doppel to the app.

Initially the Doppel app will recommend that it takes your resting heart rate before you proceed. The app features preset rhythms that you can use; from ‘alert and focused’, variations of ‘calm and focused’, ‘calm and relaxed’ and ‘energised and alert’.

There is the ability to edit these presets and save your changes. For example, with ‘calm and focused’ you can adjust how much calm or focus you want by pressing on the sound wave and making it bigger or smaller. These changes are then felt through the vibration of Doppel.

Build quality. The build quality feels good, the silicone straps seem strong and of good quality, and the metal backing of Doppel is a nice touch. The face of the device is a bit bland but as the gesture controls are performed by touch, it feels good to use.

The general experience with the dopple is good, it feels comfortable and is well designed. It’s not intrusive and can be worn discreetly.

The vibrations are silent so no one around you would know it is being used, which is a nice feature. The lub-dub vibrations are soothing and you do feel more relaxed when using it. Overall, it has the desired effect."

Read the lab report

After a long stressful day at work I sat down and set up a rhythm of a lower intensity at a slower bpm. This also had a fast acting effect, acting like a cue to relax. I wore the unit for at least an hour whilst doing some reading and forgot I was wearing it. This is a good thing!"

Dr David Broom, Faculty of Health & Wellbeing, Sheffield Hallam University
