Verdict

The call

The clearest difference is price: Audio Unit Player at Free against AMI Player Pro's $2.99. Audio Unit Player also leads on rating (3.9 vs 3.0) and ratings volume (30 vs 2). AMI Player Pro's advantage is in-app purchases (none vs 1) and ads (none vs shown). On update cadence, monetization model and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Audio Unit Player holds the better App Store score, 3.9 against 3.0. That said, the two scores are not equally well evidenced: Audio Unit Player has 30 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 67% of Audio Unit Player's written reviews are positive against 100% of AMI Player Pro's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Audio Unit Player ships an update every 2 weeks, AMI Player Pro fortnightly. The most recent releases landed on September 25, 2026 and June 21, 2026 respectively.
