Sleep Mask V2
A wireless sleep mask with coloured light. It lulls you to sleep with slow pulsing light, wakes you with a sunrise and, with an app, plays light-and-sound programs. Sound plays from your phone.
Android and iPhone · Official Sleep as Android accessory
What it does
Three modes of one mask
Light lullaby
Gentle pulsing light that gradually slows down and fades out.
Light alarm
In the morning the mask slowly lights up. With Sleep as Android it is a light alarm for the sleep recording on your phone.
Light-and-sound programs
With Brain Control or Mindroid it plays light synchronised with sound from your phone.
Sleep Mask V2 follows our first sleep mask, which we developed for Sleep as Android in 2015. Back then it was connected to the phone by a cable. Since 2020 it has been wireless and talks to your phone over Bluetooth.
We design and make the mask ourselves — the electronics, the firmware and the Brain Control app.

Safety information
The mask flashes light. Do not use it if you or anyone in your family has photosensitive epilepsy, if you have ever had a seizure, or if flashing light causes you nausea, headache or other discomfort. Stop the program immediately if you feel unwell. Do not use the mask while driving or doing anything that needs your attention. We deliberately do not show videos with fast flashing on this website.

Frequently asked questions
Does the mask have a speaker?
No. Sound plays from your phone, ideally through headphones. The mask adds synchronised light.
Is Sleep Mask V2 the same as the Bluetooth Sleep Mask?
Yes. We renamed the Bluetooth Sleep Mask to Sleep Mask V2 in 2024. The original Sleep Mask from 2015 used a cable.
Can I replace the cloth part?
Yes. The cloth mask wears out over time, so we sell it separately.
Does the mask track sleep?
No. With Sleep as Android, sleep is recorded by the app on your phone and the mask works as a light alarm.
