# Skyscraper 4D vs Blue Box Simulator

The clearest difference is ads: Skyscraper 4D at none against Blue Box Simulator's shown. Skyscraper 4D also leads on ratings volume (1.1K vs 107). Blue Box Simulator's advantage is rating (4.5 vs 4.3) and review sentiment (79% vs 70%). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Skyscraper 4D sells 16 one-off in-app purchases and Blue Box Simulator sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Blue Box Simulator holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: Skyscraper 4D has 1.1K ratings behind it against 107, so its average is the more settled of the two.
