# AiDA vs AI Chat

The clearest difference is rating: AI Chat at 4.8 against AiDA's 4.0. AI Chat also leads on ratings volume (5 vs 1). AiDA's advantage is in-app purchases (none vs 3) and review sentiment (100% vs 71%). On price, ads and device support there is nothing between them.

Both are free to download. AI Chat sells 3 in-app purchases, starting at $8.99 per 7 days. AiDA asks for nothing beyond the download.

AI Chat holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: AI Chat has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of AiDA's written reviews are positive against 71% of AI Chat's, so the app with the better star average is not the one people write more warmly about.

AiDA ships an update every 10 days, AI Chat every 3 weeks. The most recent releases landed on October 7, 2026 and October 17, 2026 respectively.
