# Diary vs Dilution Calculator

The clearest difference is in-app purchases: Diary at none against Dilution Calculator's 1. Diary also leads on ads (none vs shown) and iOS requirement (12.0 vs 17.0). On price and device support there is nothing between them.

Both are free to download. Dilution Calculator sells 1 one-off in-app purchase. Diary asks for nothing beyond the download.
