# Instrument Test Prep vs AirTest Pro

The clearest difference is in-app purchases: AirTest Pro at none against Instrument Test Prep's 4. AirTest Pro also leads on update cadence (every 3 days vs fortnightly) and review sentiment (100% vs 88%). Instrument Test Prep's advantage is ratings volume (152 vs 2). On price, rating, ads and device support there is nothing between them.

Both are free to download. Instrument Test Prep sells 4 one-off in-app purchases. AirTest Pro asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for Instrument Test Prep against 5.0 for AirTest Pro. That said, the two scores are not equally well evidenced: Instrument Test Prep has 152 ratings behind it against 2, so its average is the more settled of the two. Written reviews are what separate them: 88% of Instrument Test Prep's written reviews are positive against 100% of AirTest Pro's.

Instrument Test Prep ships an update fortnightly, AirTest Pro every 3 days. The most recent releases landed on September 24, 2026 and June 1, 2026 respectively.
