# Chat AI Plus vs ONE AI

Chat AI Plus and ONE AI both sit at 4.7 stars, but that hides the real split: 55% of Chat AI Plus's written reviews are positive against 17% of ONE AI's. Chat AI Plus also leads on ads (none vs shown) and ratings volume (1.7K vs 188). ONE AI's advantage is update cadence (weekly vs every 3 weeks) and iOS requirement (13.0 vs 16.6). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Chat AI Plus sells 15 in-app purchases, starting at $1.99 per 7 days and ONE AI sells 7 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for Chat AI Plus against 4.6 for ONE AI. That said, the two scores are not equally well evidenced: Chat AI Plus has 1.7K ratings behind it against 188, so its average is the more settled of the two. Written reviews are what separate them: 55% of Chat AI Plus's written reviews are positive against 17% of ONE AI's.

Chat AI Plus ships an update every 3 weeks, ONE AI weekly. The most recent releases landed on September 25, 2026 and September 19, 2026 respectively.
