# 聊书AI vs VAMX

The clearest difference is update cadence: 聊书AI at every 4 days against VAMX's every 14 months. 聊书AI also leads on iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 聊书AI sells 3 in-app purchases, starting at $6.99 per month and VAMX sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

聊书AI ships an update every 4 days, VAMX every 14 months. The most recent releases landed on October 13, 2026 and October 16, 2026 respectively.
