Stop guessing which window or shelf is bright enough.
LumaLeaf turns a quick phone sensor reading into practical context for everyday plant care. It is simple enough for beginners and honest about what phone sensors can and cannot do.
Save plant context
Link readings to plant profiles, compare locations, and keep a history of recent light changes.
Recover with steps
Use Plant Doctor questions and recent readings to create a clear 7-day care checklist.
Three-minute routine
Measure, compare, then act.
The app is designed for the moment you are standing near the plant and deciding what to do next.
