# Machine Yearning vs Riddle Zen

The clearest difference is ads: Machine Yearning at none against Riddle Zen's shown. Machine Yearning also leads on ratings volume (53 vs 3). Riddle Zen's advantage is rating (5.0 vs 4.8) and review sentiment (100% vs 89%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Machine Yearning sells 1 one-off in-app purchase and Riddle Zen sells 11 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Riddle Zen holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Machine Yearning has 53 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 89% of Machine Yearning's written reviews are positive against 100% of Riddle Zen's.
