# sigmoid neuron vs Neuro Sandbox

The clearest difference is iOS requirement: sigmoid neuron at 17.6 against Neuro Sandbox's 26.2. On price, ads, in-app purchases and device support there is nothing between them.

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