If you want to talk about doppel, here are the resources you’ll need to get started

We love reviews

The best way to understand doppel is to try it!

We love reviews, and so if you’d like to try one out before you write about us (or talk about us via video, radio or a podcast) then just let us know and we can send one over.

And if you’d like anything else, just email us at info@feeldoppel.com and we’ll be happy to help.

Our story

doppel started with science. The idea was inspired by cutting-edge research in psychology and neuroscience showing how humans respond intuitively and naturally to different rhythms. By applying this in a new way we realized we could help people feel calmer and more focused within moments.

After eighteen months of design and testing with hundreds of users, plus a number of scientific trials, we decided to launch on Kickstarter. We hit our target and by the end of 2015 manufacturing had begun!

Over the next two years we worked hard to solve every manufacturing challenge that came our way - the messages and feedback we received from our Kickstarter backers and pre-order customers driving our development and keeping us motivated. We even documented the journey from start to finish on our blog!

Meanwhile, we ran another scientific trial which was published and peer-reviewed in the journal Nature Scientific Reports.

We finally delivered to our Kickstarter backers at the beginning of 2018, and we began fulfilling our pre-orders straight after that. It’s been amazing to hear stories and see photos from our customers across the globe.

We’re now ready to take new orders, and we can’t wait to share doppel with the world!


The team behind doppel comprises Dr Fotini Markopoulou, Jack Hooper, Andreas Bilicki and Nell Bennett.

They met on the Innovation Design Engineering joint MSc/MA course at Imperial College London and the Royal College of Art and have spent the past four years working on technology inspired by psychophysiology - the study of the relationship between the mind and the body.

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

Chief Scientist

Professor Manos Tsakiris

Professor Manos Tsakiris’ research focuses on the neurocognitive mechanisms that shape the experience of embodiment and self-identity using a wide range of research methods, from psychometrics and psychophysics to neuroimaging. He is Professor of Psychology at the Department of Psychology, Royal Holloway, University of London, where he is also Director of Research. He has published widely in neuroscientific and psychology journals, and his current research projects investigate the plasticity of self- identity and he is leading an ERC Consolidator project. He is the recipient of the 2014 Young Mind and Brain Prize and of the 22nd Experimental Psychology Society Prize (2015). In 2016, he was confirmed as the first recipient of the NOMIS Foundation Distinguished Scientist Award.

In the press

"The slower, more relaxing rhythms were most effective on my commute home. I didn't really want to believe these small vibrations could work, but the soft, rhythmic nature of them did seem to be having a genuine impact."

"When I stuck my wrist out to try it out I had a “maybe my wife will like this” take on it, but within a few moments, I was smiling at how soothing and pleasant the experience was."

"I’m feeling a little on-edge, ready to pounce on whatever task needs taking care of next.It’s very similar to the caffeine jolt I get after a big cup of strong coffee."
