# IRNBY vs World Class

The clearest difference is in-app purchases: World Class at none against IRNBY's 26. World Class also leads on ratings volume (292 vs 30). IRNBY's advantage is rating (5.0 vs 4.8) and review sentiment (79% vs 69%). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. IRNBY sells 26 one-off in-app purchases. World Class asks for nothing beyond the download.

IRNBY holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: World Class has 292 ratings behind it against 30, so its average is the more settled of the two. Written reviews point the same way: 79% of IRNBY's written reviews are positive against 69% of World Class's.

IRNBY ships an update fortnightly, World Class monthly. The most recent releases landed on October 16, 2026 and October 18, 2026 respectively.
