# CAA vs EcoGPT

The clearest difference is in-app purchases: CAA at none against EcoGPT's 18. CAA also leads on ads (none vs shown) and iOS requirement (12.0 vs 18.0). EcoGPT's advantage is chart position (#136 vs unranked). On price and device support there is nothing between them.

Both are free to download. EcoGPT sells 18 in-app purchases, starting at $5.99 per month. CAA asks for nothing beyond the download.
