Every plant app scores the plant. GrowSpot scores the spot. Lay your phone down at the exact place you're considering, a windowsill or a shelf, and it takes a real light reading right there, then folds in temperature, humidity and airflow to judge whether that specific plant can live in that specific spot. No fake precision: estimates are labeled as estimates. Free tier: 2 spots, 2 plants with full matching, and 20 AI scans a month. iPhone and Android; free web spot checker at growspotapp.com.
