Plan and grow prosperous cities, satisfy citizens’ needs, and respond to disasters, divine unrest, and hostile forces. Inspired by classic Roman city-building simulations. • Classic City Mode Design and manage a modern city by zoning residential, commercial, and industrial areas, building infrastructure, and collecting taxes to support expansion. Maintain quality of life, balance the economy, and monitor environmental health to prevent decline or bankruptcy. Inspired by early city-building classics. • Transport Company Mode Create and operate a comprehensive transport network using trucks, buses, trains, aircraft, and ships. Connect towns and industries, deliver cargo efficiently, and reinvest profits to expand your network. Spanning 1950–2050, your objective is to achieve the highest performance rating. • Hospital Mode Build and run your own hospital.

Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
