# OrbitCalc vs SwipeDrill

The clearest difference is ads: OrbitCalc at none against SwipeDrill's shown. SwipeDrill's advantage is iOS requirement (13.0 vs 18.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. OrbitCalc sells 1 one-off in-app purchase and SwipeDrill sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
