Introducing Vesper v2
A palm-sized ambient controller that reads your room — sound, light, temperature, air quality — and gently shapes it around what you need to do.
Three modes
Raises cool-white light, lowers distractions, and plays tightly looped cognitive soundscapes tuned to 40 Hz neural entrainment.
Shifts your lights toward warm amber over 20 minutes and layers in slow, expansive soundscapes that cue your body to release the day.
Gradually dims all connected lights to off and transitions sound to deep pink noise — shown to reduce sleep latency by up to 38%.
Built-in sensing
Tracks CO₂ concentration, VOC levels, and fine particulate matter. Vesper nudges you to ventilate before you notice the brain fog.
Continuous ambient readings feed the app's comfort score and help Vesper suggest the right mode for the time of day.
Lux sensing lets Vesper compensate for changing natural light so your smart bulbs always feel right, not technically correct.
