# Crait vs 私信

The clearest difference is in-app purchases: 私信 at none against Crait's 1. 私信 also leads on rating (5.0 vs 4.7) and review sentiment (100% vs 81%). Crait's advantage is ratings volume (94 vs 1). On price, ads, device support and iOS requirement there is nothing between them.

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

私信 holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Crait has 94 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 81% of Crait's written reviews are positive against 100% of 私信's.

Crait ships an update every 2 months, 私信 every 3 weeks. The most recent releases landed on October 8, 2026 and September 26, 2026 respectively.
