# Audio Kit vs Pro

The clearest difference is rating: Pro at 4.8 against Audio Kit's 3.5. Pro also leads on in-app purchases (none vs 1) and update cadence (every 4 days vs every 6 months). Audio Kit's advantage is price ($2.99 vs $9.99). On ads, device support and iOS requirement there is nothing between them.

Audio Kit costs $2.99 and Pro $9.99 up front. Audio Kit sells 1 one-off in-app purchase. Pro asks for nothing beyond the download.

Pro holds the better App Store score, 4.8 against 3.5. That said, the two scores are not equally well evidenced: Pro has 78 ratings behind it against 6, so its average is the more settled of the two.

Audio Kit ships an update every 6 months, Pro every 4 days. The most recent releases landed on September 22, 2026 and September 26, 2026 respectively.
