Stream continuous readings with per-session minimum and maximum, switch units to match your habit, and hold to freeze the value when you need to step back from the screen.
Walk through guided calibration, pick indoor, outdoor, studio, or custom profiles, and account for paper or professional diffusers over the sensor when your setup calls for it—paired with a dark, readable interface and optional lux-tinted background or camera overlay.
Unlock smart insights with a confidence indicator, automatic labels for dark, indoor, bright, or daylight-like scenes, rough plant and PAR guidance, photography and desk-ergonomics tips, plus measurement history with charts and CSV export—still an app-based estimate, not a laboratory instrument.
