Feel calm and focused, naturally

doppel has been shown to reduce stress and increase focus. Its natural effect works within moments.

Choose your state of mind

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.

Results showing doppel’s calming effect have been published in the peer-reviewed journal Nature Scientific Reports.

A natural, psychological effect

Although doppel feels like a heartbeat, your heart rate won’t match doppel’s rhythm. It’s a natural, psychological effect. Find out more.

Shown to reduce stress and increase focus

doppel has been tested and shown to both reduce stress and increase focus. Read the results.

No activity tracking, no notifications

doppel doesn’t count steps or send notifications. Use it to feel calm and focused, anytime and anywhere.

Set your pace

Create, save and sync your personalized rhythms using the free doppel app available for both iOS and Android.

Use the doppel app to take your resting heart rate then try the five preset rhythms to feel relaxed, calm, focused, alert or energized. You can edit these presets, or create your own rhythms. Sync one rhythm at a time to the doppel wristband via Bluetooth.

Once set, the doppel wristband can be used without a phone. Use touch controls to turn doppel on and off, switch between your faster and slower rhythms, adjust the intensity of the vibration, and more.
