# International maths guide vs IMO

The clearest difference is in-app purchases: International maths guide at none against IMO's 1. IMO's advantage is iOS requirement (9.0 vs 12.0). On price, ads and device support there is nothing between them.

Both are free to download. IMO sells 1 one-off in-app purchase. International maths guide asks for nothing beyond the download.
