  • doppel works by creating a silent vibration on the inside of your wrist which feels just like the ‘lub-dub’ of a heartbeat.

    Slower rhythms are calming, and faster rhythms help you feel focused - like music.

    Use it to stay calm under pressure, focus on the task ahead of you, and keep going when you need to.

    Problems syncing and the band has broken already

    When it works it is mostly a positive experience, but it causes frustration more than I'm willing to deal with.

    Thank you for taking the time to leave a review. We're glad to hear that doppel's effect is helping you, but we're sorry about the problems you have encountered. We take feedback vey seriously and this is an improvement that is currently being worked on. Our team have arranged replacement straps to be sent out to you, so we'll follow up soon to make sure everything is ok with the replacement.

    Functional, but still buggy

    Using doppel has helped me going to bed easier and lets me concentrate on my tasks at hand, when it works.
    However the device sometimes does not recognize the gestures. (The battery indicator gesture seems to always work though) There have also been numerous times, where the device just shuts itself down without any input from my side. This might be because my sleeves hit the gesture panel, but even when I push my sleeves up, so that it does not touch the doppel, it still seems to turn itself off without any input. Syncing pulses through the app does not work half of the time. Your doppel can only save two bpm profiles, and if you want to use a different one, you have to do it through the app. The problem is, that when you sync a different profile to it, it sometimes does not save it when you close the app.

    I really like this product, when it works, but because of the constant troubleshooting you have to do, I can’t really recommend this to anyone who expects a finished product. Even I sometimes don’t want to use my doppel, because the constant bugs make it not fun to use it at all. Right now doppel seems to still be at the experimental stage and I hope that Team Turquoise will improve the device for their next iteration.

    Thank you so much for taking the time to leave us a review. We are so glad to hear that doppel is helping you to relax and focus, although I am sorry that your experience has not been entirely smooth. I have sent over an email with some troubleshooting suggestions, particularly for touch gestures, and it sounds like you are having connectivity issues. If your issues persist we can absolutely arrange a replacement for you.

    Thank you also for your feedback, take it very seriously as it really drives the improvements we make to doppel, both from a software and hardware side.

    Good Product for someone with ADHD

    I just want to say this is an amazing product.
    I bought this for me and my girlfriend.
    I have used my doppel when I need to work.
    The rhythm makes mindfulness really easy despite my ADHD.
    It is definitely one of my most used products and I’ve gotten a lot of mileage out of it already.
    Putting on my doppel is now one step in my rituals when I need to do some work.
    One thing that can definitely be improved is the strap.
    My girlfriend has lost hers on a walk because she didn’t notice it fall off while it wasn’t running.
    I had to get a 16mm watch strap from Amazon so that my doppel won’t fall of because I have noticed the ease of the strap unbuckling as well.
    I have sent an email to the doppel team and they assured me they were working on the strap, so that actually assured me.

    3.5 out of 5 stars.
    I am adding .5 stars because the customer service (especially Hannah) has been nothing if not perfect.
    I will be looking forward to any improvements to the product.

    Thank you so much for taking the time to leave us a review, it's incredible to hear that doppel is helping you in this way. We really appreciate your feedback and patience with us, the matter of the strap is definitely something we are working on improving, and we will continue to make improvements to doppel so that those who benefit from doppel the most can get the very best out of it.

    It has helped me really centre myself when I’m working and helped keep my heart rate controlled when I get stressed or anxious.

    We appreciate you taking the time to share your doppel experience, we are so glad to hear that doppels effect is working to help you in those moments of stress and anxiety.

    Doppel 🖤

    With Doppel, I think more of the form of communication with others to be a more conscious listener than a speaker.

    This is awesome! We're so glad to hear that wearing doppel is having a positive impact on your communication with others, it's really wonderful to hear.Thank for you taking the time to leave a review.
