    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.

    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.

    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.


    Definitely helps to calm me down!
    I also wear it when I go to bed..it relaxes me so I am able to fall asleep..
    I compare it to having a puppy laying beside me to soothe me when I am anxious!

    Second Time a Charm, so far!

    A 5-star product with 4-star durability. My first Doppel ceased working about 3 weeks in. Tech support was exceptional in attempts to get the device working again, to no avail. They had me a new unit in less than a week.

    This device is a bit of an odd-duck, but it is consistent in getting a calming response for me. This is NOT a smart watch or performance-measurement device, but rather syncs by vibration/entrainment to your heart rate. I was skeptical but am glad I gave the device and the company a chance.

    By nature I am chronically edgy, or anxious. I do a lot of "bio-hacking" and have succeeded in managing the angst very well. This device helps me tune that even more. I generally use it for focus/relaxation, a couple of times a day, and then at bedtime.

    It can be a little persnickety in settings or adjustments, but patience and persistence are important in using this. It is really meant for when you need calm or focus, not to be worn for say, a workout.

    At the price, well worth it! Thanks Doppel and Doppel crew!
