An ambient UV pendant that reads UV-A and UV-B and nudges behaviour through app prompts rather than just logging numbers. The point isn't the sensor, it's the habit change — turning vague sun exposure into something you actually respond to.
People who want to manage real-world UV exposure as a habit, not just measure it once.
Anyone after lab-grade dosimetry — this is a behaviour-change nudge, not a scientific instrument.
UV-A + UV-B index, ambient pendant, app-based prompts for behaviour change.
