Verdict
The clearest difference is ads: Pro at none against AppAudio's shown. Pro also leads on monetization model (free vs ad-supported). AppAudio's advantage is update cadence (every 6 weeks vs every 30 months) and review sentiment (18% vs 0%). On price, in-app purchases, device support and iOS requirement there is nothing between them.
