GrowSpot
Scores whether a specific spot in your home is right for a plant, not just the room.
GrowSpot scores a plant against the exact spot it'll live in, light, temperature, humidity, and airflow, rather than treating a whole room as one answer, since a windowsill and a shelf three meters away can sit in different light bands entirely. On iPhone, laying a sheet of white printer paper over the front camera turns the reading into an actual light measurement instead of a guess. It never asks for photos of your home, and daily watering reminders adjust to the day's actual weather instead of running off a fixed schedule.

What holds up
- +Measures the actual spot with your phone's camera and light sensor, not just a room guess.
- +Never asks to photograph your home — only the plant and the reading, stated in its permissions.
- +Adjusts watering reminders to the day's real weather instead of a fixed calendar schedule.
Mind the limits
- −iPhone's accurate light reading needs a sheet of white paper over the camera — an extra manual step.
- −App pricing isn't shown on this page — only the free web spot-checker is detailed.
