# Convert vs QROX

The clearest difference is in-app purchases: QROX at none against Convert's 2. QROX also leads on ratings volume (215 vs 1). Convert's advantage is ads (none vs shown) and rating (5.0 vs 4.6). On price, review sentiment and update cadence there is nothing between them.

Both are free to download. Convert sells 2 one-off in-app purchases. QROX asks for nothing beyond the download.

Convert 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 1, so its average is the more settled of the two. Written reviews complicate that: 60% of Convert's written reviews are positive against 68% of QROX's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 5 weeks. The most recent releases landed on September 10, 2026 and September 30, 2026 respectively.
