# OrbitCalc vs Exam Pass LPI

The clearest difference is device support: Exam Pass LPI at 3 against OrbitCalc's 1. Exam Pass LPI also leads on iOS requirement (15.0 vs 18.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. OrbitCalc sells 1 one-off in-app purchase and Exam Pass LPI sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
