# Keep vs 半月湾

The clearest difference is ads: 半月湾 at none against Keep's shown. 半月湾 also leads on review sentiment (73% vs 52%). Keep's advantage is ratings volume (17K vs 27) and rating (4.8 vs 4.6). On price, update cadence, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Keep sells 12 in-app purchases, starting at $2.99 per month and 半月湾 sells 27 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Keep holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Keep has 17K ratings behind it against 27, so its average is the more settled of the two. Written reviews complicate that: 52% of Keep's written reviews are positive against 73% of 半月湾's, so the app with the better star average is not the one people write more warmly about.

Keep ships an update weekly, 半月湾 every 2 weeks. The most recent releases landed on October 27, 2026 and October 20, 2026 respectively.
