# School Days HD vs Ultimate Destruction Simulator

The clearest difference is ads: School Days HD at none against Ultimate Destruction Simulator's shown. School Days HD also leads on iOS requirement (10.0 vs 14.0). Ultimate Destruction Simulator's advantage is update cadence (every 2 weeks vs every 3 months) and device support (3 vs 1). On price, rating, review sentiment and ratings volume there is nothing between them.

Both are free to download. School Days HD sells 1 one-off in-app purchase and Ultimate Destruction Simulator sells 14 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Ultimate Destruction Simulator holds the better App Store score, 4.2 against 4.0. Both are backed by a comparable volume of ratings — 369 and 244 respectively. Written reviews complicate that: 62% of School Days HD's written reviews are positive against 55% of Ultimate Destruction Simulator's, so the app with the better star average is not the one people write more warmly about.

School Days HD ships an update every 3 months, Ultimate Destruction Simulator every 2 weeks. The most recent releases landed on October 24, 2026 and October 23, 2026 respectively.
