  • Compatible with all Bluetooth LE enabled smartphones

Ships to USA, Canada and Europe. We expect to ship in Summer 2017. See below for more details.

Our pre-order form is hosted by our secure payment processor Paywhirl. You will only be charged when doppel is shipped.


Communications

We are currently manufacturing doppel. Whilst we expect to ship in Summer 2017, there may be unexpected delays. We may have to adjust the design slightly, or parts may be held up in customs. When you pre-order you’ll receive an email update from the team every other Tuesday to let you know how things are going. You can see which stage we're up to at the bottom of this blog post.

Compatible with your smartphone

doppel works with a companion app but once set you can leave your phone behind. The app stores your personal rhythms, each one linked to your own resting heart rate, and you can upload new pairs at any time.

Delivery and returns

Delivery - You will only be charged when doppel is shipped. We expect to ship in Summer 2017. Our shipping prices are as follows: £5 United Kingdom, £10 Europe, and £15 North America.

Cancellations - If you change your mind and would like to cancel your pre-order before we ship, simply email us at info@doppel.london.

Returns - doppel is very new and is unlikely to be something you have experienced before. You may need to give it some time to get used to. For that reason we have given you an extended return policy of 60 days. As long as your doppel is not damaged we will take it back and find another home for it. So you have a chance to give it a real go and see how you find it.
