Verdict

The call

The clearest difference is rating: iMSX2 at 3.4 against Klaverjas's 3.0. iMSX2 also leads on ratings volume (10 vs 1) and chart position (#79 vs unranked). Klaverjas's advantage is review sentiment (71% vs 59%) and price ($0.99 vs $1.99). On update cadence, ads, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

iMSX2 holds the better App Store score, 3.4 against 3.0. That said, the two scores are not equally well evidenced: iMSX2 has 10 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 71% of Klaverjas's written reviews are positive against 59% of iMSX2's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on September 23, 2026 and September 22, 2026 respectively.
