# Virtual Hydraulic Test Rigs vs Neural Network

The clearest difference is iOS requirement: Virtual Hydraulic Test Rigs at 13.2 against Neural Network's 15.6. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Virtual Hydraulic Test Rigs sells 1 one-off in-app purchase and Neural Network sells 3 in-app purchases, starting at $12.99 per 6 months. Whichever you choose, the download price is not the number that matters.
