# The Diary by YYM vs uStory

The clearest difference is update cadence: uStory at every 2 months against The Diary by YYM's every 23 months. uStory also leads on rating (4.3 vs 4.0). The Diary by YYM's advantage is review sentiment (89% vs 67%) and iOS requirement (8.0 vs 15.0). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. The Diary by YYM sells 1 one-off in-app purchase and uStory sells 8 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

uStory holds the better App Store score, 4.3 against 4.0. Both are backed by a comparable volume of ratings — 9 and 6 respectively. Written reviews complicate that: 89% of The Diary by YYM's written reviews are positive against 67% of uStory's, so the app with the better star average is not the one people write more warmly about.

The Diary by YYM ships an update every 23 months, uStory every 2 months. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
