The story
Mara moved into a small flat on Sunday, and by Wednesday evening she still had not decided where her reading chair should go. The living room has a ceiling light, one floor lamp and a window that is useless after sunset. Every corner looked fine for about five minutes and then her eyes started to feel tired halfway through a chapter.
She already wears a Wear OS watch, so she opened WristLux and set it to the reading mode. Standing by the window corner, she held her wrist where the book would be and saw the live lux number settle. She held that reading so it stayed on screen.
Then she walked to the corner next to the floor lamp. The live meter climbed while the held value from the window corner stayed beside it, so the difference was right there on her wrist without writing anything down. The lamp corner was clearly brighter.
To be sure, she started a session and did a slow lap of the room with her wrist at the same height. The session showed the minimum, the maximum and the average when she stopped. The minimum came from the spot behind the sofa, the maximum from right under the floor lamp. That confirmed what she half suspected: the ceiling light alone was not doing much for reading.
She pushed the chair into the lamp corner and took one more reading from the seat itself, then saved it. Now the number sits on her Tile, along with how fresh it is, so on Thursday she can glance at it before changing anything.
She knows the reading is a rough reference. Her sleeve and the angle of her wrist moved it a little, so she kept her arm in the same position for every check. That was enough to compare corners in her own flat, which was all she needed.

Questions
Is it accurate enough to compare spots in my own home?
Yes, as a rough guide. Use the same watch and hold your wrist the same way for each spot, since angle and shadows change the number.
Source: play.google.comWill the Tile drain my battery by measuring all day?
No. The Tile and complication do not keep polling the sensor in the background; they show the last reading the app saved.
Source: play.google.comCan I use it to check a grow light?
Yes. Plant placement and grow-light checks are listed uses, and there is a plant mode. Treat the number as a rough guide.
Source: play.google.comWill two different watches give the same number?
Not always. Readings depend on the watch model and where its sensor sits, so two watches can disagree in the same spot.
Source: play.google.comIs there a watch face complication?
Yes. A complication on your watch face shows the latest reading you saved in the app.
Source: play.google.comDoes holding a reading stop the live meter?
No. The held number stays on screen while the live meter keeps measuring next to it.
