# Plant Light Meter vs Vsensor

The clearest difference is price: Vsensor at Free against Plant Light Meter's $2.99. Vsensor also leads on review sentiment (60% vs 39%). Plant Light Meter's advantage is rating (4.6 vs 3.0) and ratings volume (1.1K vs 8). On update cadence, ads, in-app purchases and monetization model there is nothing between them.

Vsensor is free to download; Plant Light Meter costs $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Plant Light Meter holds the better App Store score, 4.6 against 3.0.
