Every plant app scores the plant. GrowSpot scores the spot. Lay your phone down at the exact place you're considering - a windowsill, a shelf, the corner by the AC - 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. It re-scores as seasons change and compares two spots head to head.
No fake precision: estimates are labeled as estimates. Free tier: 2 spots, 2 plants, full features, 20 photo IDs a month. On iPhone and Android; there is also a free web spot checker at growspotapp.com - no sign-up, open it and check a spot. Founding offer: 90 days of GrowSpot Plus free on iPhone and Android, claim at growspotapp.com/founding
