# TraceArt vs QR Engine

The clearest difference is in-app purchases: QR Engine at none against TraceArt's 1. QR Engine also leads on ads (none vs shown) and update cadence (every 2 months vs every 3 months). TraceArt's advantage is iOS requirement (14.2 vs 17.6). On price and device support there is nothing between them.

Both are free to download. TraceArt sells 1 one-off in-app purchase. QR Engine asks for nothing beyond the download.

TraceArt ships an update every 3 months, QR Engine every 2 months. The most recent releases landed on October 9, 2026 and October 8, 2026 respectively.
