# AppAudio vs Pro

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.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

AppAudio ships an update every 6 weeks, Pro every 30 months. The most recent releases landed on September 28, 2026 and June 25, 2026 respectively.
