# My vs SigmaQuest

The clearest difference is in-app purchases: My at none against SigmaQuest's 10. My also leads on ads (none vs shown) and iOS requirement (13.0 vs 18.0). On price and device support there is nothing between them.

Both are free to download. SigmaQuest sells 10 one-off in-app purchases. My asks for nothing beyond the download.
