Is your windowsill bright enough for your plant? Start with a light reading. LumaLeaf uses your phone’s ambient light sensor to measure lux where the leaves sit. Save the spot, compare readings, and keep useful records for your houseplants. START WITHOUT AN ACCOUNT - Go straight to a light check from the welcome screen - Measure the light at leaf level - Save readings for windowsills, shelves, and grow-light spots - Link a reading to a plant or compare the same spot over time TURN READINGS INTO CARE STEPS - Search a local catalog of 500 plant entries - Browse plant suggestions based on the current light reading - Use the Plant Doctor questionnaire to explore possible care issues - Review measurement history and weekly light insights - Choose optional reminders and a home-screen widget YOUR LANGUAGE, YOUR CHOICE Switch between English, Korean, and other supported languages in settings, or follow your device language. Core light checks and plant records work without signup. The app contains ads. BEFORE YOU MEASURE Live lux readings require a phone with an ambient light sensor. Results vary by device, angle, and time of day. Compare spots under similar conditions and consider watering, plant condition, and changes in daylight too. Plant Doctor provides questionnaire-based care guidance. It is not a professional diagnosis, and LumaLeaf does not replace a professional PPFD or DLI meter. Camera and notification permissions are requested when you choose those features. Try the spot where your plant sits today.
