# Water Box vs Ultimate Coaster 3

The clearest difference is rating: Water Box at 4.8 against Ultimate Coaster 3's 3.6. Water Box also leads on review sentiment (92% vs 57%) and ratings volume (1.8K vs 224). Ultimate Coaster 3's advantage is ads (none vs shown) and update cadence (every 4 days vs every 9 days). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Water Box sells 10 one-off in-app purchases and Ultimate Coaster 3 sells 23 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Water Box holds the better App Store score, 4.8 against 3.6.
