# Hydrothermal Lite vs CTMayor

The clearest difference is in-app purchases: Hydrothermal Lite at none against CTMayor's 1. Hydrothermal Lite also leads on rating (4.0 vs 3.8). CTMayor's advantage is ratings volume (41 vs 2) and device support. On price and review sentiment there is nothing between them.

Both are free to download. CTMayor sells 1 in-app purchase, starting at $0.99 per year. Hydrothermal Lite asks for nothing beyond the download.

Hydrothermal Lite holds the better App Store score, 4.0 against 3.8. That said, the two scores are not equally well evidenced: CTMayor has 41 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 40% of Hydrothermal Lite's written reviews are positive against 46% of CTMayor's, so the app with the better star average is not the one people write more warmly about.
