# Thermal Effect vs Thermal Master

The clearest difference is rating: Thermal Effect at 4.4 against Thermal Master's 2.5. Thermal Effect also leads on update cadence (daily vs every 3 weeks) and ratings volume (155 vs 15). Thermal Master's advantage is in-app purchases (none vs 2) and review sentiment (36% vs 22%). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Thermal Effect sells 2 in-app purchases, starting at $4.99 per 7 days. Thermal Master asks for nothing beyond the download.

Thermal Effect holds the better App Store score, 4.4 against 2.5. That said, the two scores are not equally well evidenced: Thermal Effect has 155 ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 22% of Thermal Effect's written reviews are positive against 36% of Thermal Master's, so the app with the better star average is not the one people write more warmly about.

Thermal Effect ships an update daily, Thermal Master every 3 weeks. The most recent releases landed on October 10, 2026 and October 12, 2026 respectively.
