Frequently asked questions (FAQ).

Clear answers about EEG, meditation, setup, data, compatibility, and purchasing.

Product and practice.

What does SereniBrain measure?

SereniBrain uses EEG (electroencephalography) sensors at the forehead to record small changes in electrical activity. The app processes supported patterns into session feedback and reports.

How does feedback help meditation?

Feedback makes changes during practice easier to notice. When your attention shifts, the audio or visual experience can change, giving you a cue to return to the practice.

Can I use SereniBrain for focus practice?

Yes. Eyes-open practice can combine audio and visual feedback. It is designed to help you notice distraction and practice returning your attention.

Is SereniBrain a medical device?

No. SereniBrain is a consumer wellness product and is not intended to diagnose, treat, cure, or prevent any medical condition.

Setup and comfort.

How do I know the signal is connected?

The app shows connection status before practice. Adjust the band and electrode position until the app confirms a usable connection.

How long should a session be?

Start with a short session you can repeat consistently. Many users begin with 5–10 minutes and adjust the length to fit their routine.

How often should the hydrogel contacts be replaced?

Replacement timing depends on use, storage, and contact quality. Follow the care instructions supplied with your device and replace them when adhesion or signal quality declines.

Does the core app require a subscription?
