The clearest difference is price: AUDIIO at Free against iAudioTool's $2.99. AUDIIO also leads on rating (4.3 vs 3.3) and ratings volume (100 vs 13). iAudioTool's advantage is review sentiment (35% vs 0%) and in-app purchases (none vs 1). On update cadence, device support and iOS requirement there is nothing between them.

AUDIIO is free to download; iAudioTool costs $2.99 up front. AUDIIO sells 1 one-off in-app purchase. iAudioTool asks for nothing beyond the download.

AUDIIO holds the better App Store score, 4.3 against 3.3. That said, the two scores are not equally well evidenced: AUDIIO has 100 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 35% of iAudioTool's written reviews are positive against 0% of AUDIIO's, so the app with the better star average is not the one people write more warmly about.

iAudioTool ships an update every 2 months, AUDIIO every 3 months. The most recent releases landed on November 10, 2026 and November 3, 2026 respectively.
