# ぼくらの瞬間英作文 vs Language Diary

The clearest difference is rating: ぼくらの瞬間英作文 at 5.0 against Language Diary's 4.4. Language Diary's advantage is review sentiment (89% vs 74%) and ratings volume (27 vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. ぼくらの瞬間英作文 sells 11 in-app purchases, starting at $2.99 per month and Language Diary sells 6 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

ぼくらの瞬間英作文 holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Language Diary has 27 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 74% of ぼくらの瞬間英作文's written reviews are positive against 89% of Language Diary's, so the app with the better star average is not the one people write more warmly about.

ぼくらの瞬間英作文 ships an update every 5 days, Language Diary every 3 days. The most recent releases landed on October 18, 2026 and October 22, 2026 respectively.
