# Diary vs Polylog

The clearest difference is review sentiment: Diary at 100% against Polylog's 0%. Diary also leads on rating (4.1 vs 2.0) and ads (none vs shown). Polylog's advantage is update cadence (fortnightly vs every 6 weeks) and iOS requirement (11.0 vs 16.6). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Diary sells 1 one-off in-app purchase and Polylog sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
