# Ruler vs TypewriterDiary

The clearest difference is in-app purchases: TypewriterDiary at none against Ruler's 1. TypewriterDiary also leads on ads (none vs shown). Ruler's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 18.5). On price there is nothing between them.

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