# Thermal P2 vs W01

The clearest difference is rating: Thermal P2 at 2.1 against W01's 1.0. Thermal P2 also leads on device support and iOS requirement (11.0 vs 13.0). W01's advantage is monetization model (free vs paid) and review sentiment (20% vs 11%). On price, ratings volume 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.

Thermal P2 holds the better App Store score, 2.1 against 1.0. Both are backed by a comparable volume of ratings — 27 and 13 respectively. Written reviews complicate that: 11% of Thermal P2's written reviews are positive against 20% of W01's, so the app with the better star average is not the one people write more warmly about.
