# WorldTour Study vs Flag Learning Quiz

The clearest difference is in-app purchases: Flag Learning Quiz at none against WorldTour Study's 1. Flag Learning Quiz also leads on ads (none vs shown). WorldTour Study's advantage is iOS requirement (8.0 vs 13.0). On price and device support there is nothing between them.

Both are free to download. WorldTour Study sells 1 one-off in-app purchase. Flag Learning Quiz asks for nothing beyond the download.
