Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
