# Thermal P2 vs Fluke iSee

The clearest difference is monetization model: Fluke iSee at free against Thermal P2's paid. Fluke iSee also leads on rating (2.3 vs 2.1). Thermal P2's advantage is update cadence (fortnightly vs every 4 months) and ratings volume (27 vs 9). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Fluke iSee holds the better App Store score, 2.3 against 2.1. Both are backed by a comparable volume of ratings — 27 and 9 respectively. Written reviews complicate that: 11% of Thermal P2's written reviews are positive against 8% of Fluke iSee's, so the app with the better star average is not the one people write more warmly about.

Thermal P2 ships an update fortnightly, Fluke iSee every 4 months. The most recent releases landed on September 16, 2026 and September 8, 2026 respectively.
