ReceptionRating · Positive reviews · Number of ratings

AI Chat holds the better App Store score, 4.7 against 2.0. That said, the two scores are not equally well evidenced: AI Chat has 1.7K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 69% of AI Chat's written reviews are positive against 45% of AIチャット's.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on September 26, 2026 and September 14, 2026 respectively.
