Verdict

The call

The clearest difference is rating: ChatX at 4.6 against invsi's 4.1. ChatX also leads on ratings volume (481 vs 8) and device support (4 vs 2). On price, review sentiment, update cadence and ads there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. invsi sells 4 in-app purchases, starting at $0.99 per month and ChatX sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

ChatX holds the better App Store score, 4.6 against 4.1. That said, the two scores are not equally well evidenced: ChatX has 481 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 96% of invsi's written reviews are positive against 88% of ChatX's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

invsi ships an update every 3 weeks, ChatX fortnightly. The most recent releases landed on October 18, 2026 and October 17, 2026 respectively.
