# Pocket MRS vs Dirac equation

The clearest difference is iOS requirement: Pocket MRS at 14.2 against Dirac equation's 17. 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.
