# Aircraft Engine vs VRTX

The clearest difference is review sentiment: VRTX at 100% against Aircraft Engine's 25%. VRTX also leads on rating (5.0 vs 2.1). Aircraft Engine's advantage is in-app purchases (none vs 23) and update cadence (every 3 days vs every 3 weeks). On price, ads and device support there is nothing between them.

Both are free to download. VRTX sells 23 one-off in-app purchases. Aircraft Engine asks for nothing beyond the download.

VRTX holds the better App Store score, 5.0 against 2.1. That said, the two scores are not equally well evidenced: Aircraft Engine has 18 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 25% of Aircraft Engine's written reviews are positive against 100% of VRTX's.

Aircraft Engine ships an update every 3 days, VRTX every 3 weeks. The most recent releases landed on September 27, 2026 and September 9, 2026 respectively.
