# Thread Fever vs Wool Knit

The clearest difference is review sentiment: Thread Fever at 41% against Wool Knit's 0%. Thread Fever also leads on ratings volume (1.4K vs 5). Wool Knit's advantage is ads (none vs shown) and rating (5.0 vs 4.8). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Thread Fever sells 16 one-off in-app purchases and Wool Knit sells 13 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Wool Knit holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Thread Fever has 1.4K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 41% of Thread Fever's written reviews are positive against 0% of Wool Knit'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, Wool Knit every 5 days. The most recent releases landed on October 14, 2026 and September 24, 2026 respectively.
