About this app
As soon as you open the app, the brightness (lux) of your current location is immediately displayed on the large dashboard. Check at a glance whether the lighting is appropriate for your study, office, bedroom, or plant area.
✔ Illumination Dashboard at a Glance
＊ Logarithmic scale dashboard from 1 to 100,000 lx for accurate readings from dark rooms to midday sunlight
＊ Brightness level indicators: Very dark · Medium indoor lighting · Bright indoor · Under sunlight …
* Displays both Lux (lx) and Foot Candle (fc) units together, and immediately shows the unit currently in use.
* Press the gauge or [Stop] to pause the readings, allowing you to read them slowly.
* Max, average, and minimum values, along with a brightness graph for the last 1 minute.
✔ Recommended Brightness by Use (New Feature)
* Study/Reading, Office/Computer, Living Room, Kitchen Countertop, Bedroom, Hallway/Stairs, Vanity/Mirror, Indoor Plants
* Select a use category, and it compares the current brightness with the recommended level to inform you: "Just Right / Too Dark / About ○○ lx Brighter."
* Great for replacing lights, choosing lamp positions, or checking a child's study room.
✔ Precise Calibration
* Light sensors vary slightly from phone to phone.
* Adjust the magnification (×0.5 ~ ×1.5) manually, or input a value measured with an accurate light meter for automatic calibration.
* Continue using previously set calibration values.
✔ Illuminance Logging
* Save date, time, value, and memo with a single [Record] click.
* Logs monthly. Edit and delete graphs, lists, and notes
* Save to Excel (CSV), save and load backup files — your past records remain intact
✔ To measure accurately
* The light sensor is usually located at the top front of the phone (near the front camera).
* Point the screen toward the light source and ensure it is not obscured by hands, a phone case, or shadows.
* For desk brightness, place the phone on the desk with the screen facing up.
✔ Suitable for:
* Parents curious about the brightness of a child's study room or reading light
* Those checking office or workplace lighting
* Those choosing locations for indoor plants
* Those adjusting lighting for photography or videography
※ Uses the phone's light sensor (for automatic screen brightness). Values may differ slightly from a professional light meter, so please use [Precise Calibration] if necessary.
※ Recommended brightness is a reference value based on general recommended ranges, such as KS illuminance standards.
