# 3LINEDIARY vs 공유일기

The clearest difference is rating: 공유일기 at 5.0 against 3LINEDIARY's 4.4. 공유일기 also leads on in-app purchases (none vs 1) and update cadence (every 5 days vs fortnightly). 3LINEDIARY's advantage is ratings volume (48 vs 1) and device support. On price and iOS requirement there is nothing between them.

Both are free to download. 3LINEDIARY sells 1 in-app purchase, starting at $2.99 per month. 공유일기 asks for nothing beyond the download.

공유일기 holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: 3LINEDIARY has 48 ratings behind it against 1, so its average is the more settled of the two.

3LINEDIARY ships an update fortnightly, 공유일기 every 5 days. The most recent releases landed on September 17, 2026 and September 15, 2026 respectively.
