# One vs ChalkFive

The clearest difference is in-app purchases: ChalkFive at none against One's 1. ChalkFive also leads on ads (none vs shown). One's advantage is iOS requirement (12.0 vs 14.0). On price and device support there is nothing between them.

Both are free to download. One sells 1 one-off in-app purchase. ChalkFive asks for nothing beyond the download.
