# QROX vs IUSA Smart

The clearest difference is ads: IUSA Smart at none against QROX's shown. IUSA Smart also leads on rating (5.0 vs 4.6) and monetization model (free vs free with in-app purchases). QROX's advantage is update cadence (every 5 weeks vs every 28 months) and ratings volume (215 vs 3). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

IUSA Smart holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: QROX has 215 ratings behind it against 3, so its average is the more settled of the two.

QROX ships an update every 5 weeks, IUSA Smart every 28 months. The most recent releases landed on October 4, 2026 and October 6, 2026 respectively.
