# The Random Number Generator! vs Lotto Engine 2D

The clearest difference is ads: Lotto Engine 2D at none against The Random Number Generator!'s shown. Lotto Engine 2D also leads on review sentiment (100% vs 80%) and iOS requirement (13.0 vs 15.0). The Random Number Generator!'s advantage is ratings volume (836 vs 14) and update cadence (every 2 weeks vs every 5 weeks). On price, in-app purchases and monetization model there is nothing between them.

Both are free to download. The Random Number Generator! sells 4 in-app purchases, starting at $0.99 per month and Lotto Engine 2D sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

The Random Number Generator! holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: The Random Number Generator! has 836 ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 80% of The Random Number Generator!'s written reviews are positive against 100% of Lotto Engine 2D's, so the app with the better star average is not the one people write more warmly about.

The Random Number Generator! ships an update every 2 weeks, Lotto Engine 2D every 5 weeks. The most recent releases landed on September 21, 2026 and July 6, 2026 respectively.
