ThetaMask is a light-based instrument that gives recovery a fixed place in high-pressure work. Research suggests guided wind-down between demands may help the nervous system settle before the next one.
Mask delivers light. The app delivers sound.
The mask uses integrated LEDs and an infinity-mirror effect to deliver photic (light) entrainment. The companion app handles audio entrainment separately, through your own headphones. Used together, this audiovisual brainwave entrainment guides the brain toward slower theta and alpha rhythms.
The mask emits light only. There is no speaker in the mask.
The evidence base
What stands behind the instrument
The evidence, stated honestly
Studies show brainwave entrainment may support relaxed, recovered states. We describe what the research does and does not establish: the evidence by outcome, twelve citations, and a clear safety note.

Safety note: photic stimulation can affect people with photosensitive epilepsy. Anyone with a seizure history or photosensitivity should consult a clinician before use.

Built, tested, and studied in one loop.
Every part of the instrument is developed by the same small team. What user testing and research surface in one revision is built into the next.
- Hardware
- Industrial design, optics, and electronics developed in-house, printed and assembled on our own bench.
- Firmware
- Light programs run on our own controller firmware, revised as the research asks.
- Software
- The companion app is built alongside the hardware it drives.
- Research
- User testing and research with academic partners feed hardware and program revisions.
The next instruments will come out of the same loop.
Built for demanding work
Decompress between demands
A short session is designed to settle the nervous system before the next task, briefing or shift.
Recovery after sustained pressure
After long stretches at high tempo, entrainment toward slower rhythms may ease the drop out of a keyed-up state and into rest.
A way into meditative states
EEG studies link these rhythms to states seen in experienced meditators. Entrainment may make them easier to reach without years of practice.
Partnership
For research and institutional partners
ThetaMask is pre-beta and not for sale. We work with research and institutional partners on studies and pilots. Tell us about your context and we will follow up.
