# Thread Fever vs Yarn Jam

The clearest difference is review sentiment: Yarn Jam at 100% against Thread Fever's 41%. Yarn Jam also leads on ads (none vs shown). Thread Fever's advantage is rating (4.8 vs 3.0) and ratings volume (1.7K vs 2). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Thread Fever sells 10 one-off in-app purchases and Yarn Jam sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Thread Fever holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: Thread Fever has 1.7K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 41% of Thread Fever's written reviews are positive against 100% of Yarn Jam's, so the app with the better star average is not the one people write more warmly about.

Thread Fever ships an update every 11 days, Yarn Jam every 3 weeks. The most recent releases landed on November 8, 2026 and October 31, 2026 respectively.
