# AudioCopy vs AUM

The clearest difference is review sentiment: AUM at 82% against AudioCopy's 26%. AUM also leads on rating (4.7 vs 3.7) and ratings volume (535 vs 25). AudioCopy's advantage is price (Free vs $24.99). On update cadence, ads, in-app purchases and monetization model there is nothing between them.

AudioCopy is free to download; AUM costs $24.99 up front. AudioCopy sells 10 one-off in-app purchases and AUM sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

AUM holds the better App Store score, 4.7 against 3.7. That said, the two scores are not equally well evidenced: AUM has 535 ratings behind it against 25, so its average is the more settled of the two. Written reviews point the same way: 26% of AudioCopy's written reviews are positive against 82% of AUM's.

Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on November 6, 2026 and November 7, 2026 respectively.
