Verdict

The call

The clearest difference is rating: Pro Microphone at 3.7 against AloneQuartet's 3.1. Pro Microphone also leads on ratings volume (8.4K vs 7) and update cadence (every 2 weeks vs monthly). AloneQuartet's advantage is review sentiment (33% vs 13%). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Pro Microphone holds the better App Store score, 3.7 against 3.1. That said, the two scores are not equally well evidenced: Pro Microphone has 8.4K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 13% of Pro Microphone's written reviews are positive against 33% of AloneQuartet's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Pro Microphone ships an update every 2 weeks, AloneQuartet monthly. The most recent releases landed on October 18, 2026 and October 3, 2026 respectively.
