# AllNum vs Lotto Engine 2D

The clearest difference is update cadence: Lotto Engine 2D at every 5 weeks against AllNum's every 8 months. AllNum's advantage is iOS requirement (11.4 vs 13.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. AllNum sells 1 one-off in-app purchase and Lotto Engine 2D sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
