Plant Light Meter for Houseplants
LumaLeaf is built for the everyday question: is this window, shelf, desk, or grow-light spot bright enough for my plant?
What the app measures
The app reads lux from the phone light sensor. Lux is useful for comparing spots in a home, but phone sensors are not calibrated like professional meters.
How the result becomes useful
The updated result screen lets you save the spot, link the reading to a plant, or add a recommended plant from the local 500-plant catalog.
Safe expectation
Use LumaLeaf for home care decisions and trend tracking. Use a dedicated meter for professional PPFD, DLI, or crop work.
