# Judokai vs TUL TKD ITF

The clearest difference is in-app purchases: TUL TKD ITF at none against Judokai's 10. TUL TKD ITF also leads on rating (5.0 vs 4.7). Judokai's advantage is update cadence (every 3 weeks vs every 7 months) and ratings volume (191 vs 3). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Judokai sells 10 one-off in-app purchases. TUL TKD ITF asks for nothing beyond the download.

TUL TKD ITF holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Judokai has 191 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 74% of Judokai's written reviews are positive against 57% of TUL TKD ITF's, so the app with the better star average is not the one people write more warmly about.

Judokai ships an update every 3 weeks, TUL TKD ITF every 7 months. The most recent releases landed on October 26, 2026 and October 22, 2026 respectively.
