Verdict
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. That said, the two scores are not equally well evidenced: Plant Light Meter has 1.1K ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 39% of Plant Light Meter's written reviews are positive against 60% of Vsensor's, so the app with the better star average is not the one people write more warmly about.
Plant Light Meter ships an update fortnightly, Vsensor every 3 weeks. The most recent releases landed on September 25, 2026 and August 18, 2026 respectively.
