# VibeLang vs AI英文测验

The clearest difference is in-app purchases: AI英文测验 at none against VibeLang's 1. AI英文测验 also leads on update cadence (every 5 days vs every 5 weeks). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. VibeLang sells 1 in-app purchase, starting at $1.99 per month. AI英文测验 asks for nothing beyond the download.

VibeLang ships an update every 5 weeks, AI英文测验 every 5 days. The most recent releases landed on October 24, 2026 and October 29, 2026 respectively.
