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.
