## What is Plant Light Meter?

Is this spot bright enough for your plant? Aim your iPhone at the leaves and find out.

Plant Light Meter turns the camera into a light meter for houseplants. Pick a plant, point at the leaves, and a live gauge shows how well the light suits it: a score out of 100, a clear verdict, and a simple tip like "move closer to a window."

FREE
• A live fit score for 42 popular houseplants, from snake plants and pothos to fiddle leaf figs and orchids
• The full plant library, with the light range each plant likes

PREMIUM
• PPFD and DLI, the numbers growers use, for sunlight, indoor lamps, or LED grow lights
• Saved spots: see whether a windowsill got brighter or dimmer since last time
• Plants that would thrive here: every plant ranked for the light you're measuring
• Light log: prop your phone by a window for 1–8 hours and get an approximate daily light total
• Seasons: see how a window's light changes through the year, with a heads-up before the darker months
• Calibration, plus care and placement notes for every plant

PRIVATE BY DESIGN
No account, no ads, no tracking. The camera reads brightness on your iPhone. Frames are never saved or uploaded, and your spots stay on your device.

A NOTE ON ACCURACY
A phone camera isn't a lab instrument. Every reading is an estimate from the camera's exposure: great for comparing spots and deciding where a plant should go, not for scientific measurement.
