# ScreenQuest vs Voltage

The clearest difference is device support: ScreenQuest at 3 against Voltage's 1. ScreenQuest also leads on iOS requirement (15.1 vs 18.2). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. ScreenQuest sells 2 one-off in-app purchases and Voltage sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
