    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.
