Verdict
The Audio Converter and M4Bindr both sit at 4.6 stars, but that hides the real split: 100% of M4Bindr's written reviews are positive against 35% of The Audio Converter's. M4Bindr also leads on update cadence (every 5 days vs every 2 months) and monetization model (free vs free with in-app purchases). The Audio Converter's advantage is ratings volume (14K vs 8). On price, rating, ads and in-app purchases there is nothing between them.
