# iTurbo vs Stochastic Processes

The clearest difference is device support: iTurbo at 2 against Stochastic Processes's —. Stochastic Processes's advantage is iOS requirement (12.0 vs 18.0). On price and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
