# iKnow! vs わせコマ

The clearest difference is review sentiment: iKnow! at 79% against わせコマ's 34%. iKnow! also leads on ratings volume (491 vs 2). わせコマ's advantage is in-app purchases (none vs 10) and rating (5.0 vs 4.8). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. iKnow! sells 10 one-off in-app purchases. わせコマ asks for nothing beyond the download.

わせコマ holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: iKnow! has 491 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 79% of iKnow!'s written reviews are positive against 34% of わせコマ's, so the app with the better star average is not the one people write more warmly about.

iKnow! ships an update every 5 weeks, わせコマ monthly. The most recent releases landed on October 24, 2026 and October 5, 2026 respectively.
