# 小牛加速器 vs Metl AI

小牛加速器 and Metl AI both sit at 4.4 stars, but that hides the real split: 90% of Metl AI's written reviews are positive against 17% of 小牛加速器's. Metl AI also leads on update cadence (every 3 days vs weekly). 小牛加速器's advantage is ratings volume (160 vs 9) and iOS requirement (15.6 vs 18.0).

Both are free to download. 小牛加速器 sells 3 one-off in-app purchases and Metl AI sells 9 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
