Keep calm and focused, naturally

doppel works with your body’s natural response to rhythm to change how you feel on demand.

doppel creates a rhythmic pulse that you feel on the inside of your wrist as a heartbeat like vibration. We do not simply perceive this rhythm, but we entrain to it - a faster rhythm makes us feel more alert, and a slower one calms us down. The effect is similar to listening to upbeat or slower music.

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

Set your pace

doppel works with a companion app but once set you can leave your phone behind.

Change to the slower rhythm by stroking the device or give it a short sharp tap to feel the faster beat kick in.

The app stores your personal rhythms, each one linked to your own resting heart rate, and you can upload new pairs at any time.
