# Vibration vs Audio Memos

The clearest difference is price: Audio Memos at $0.99 against Vibration's $9.99. Audio Memos also leads on ratings volume (668 vs 9) and chart position (#8 vs #127). Vibration's advantage is review sentiment (79% vs 61%). On rating, update cadence, ads and in-app purchases there is nothing between them.

Vibration costs $9.99 and Audio Memos $0.99 up front. Vibration sells 1 one-off in-app purchase and Audio Memos sells 4 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Audio Memos holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Audio Memos has 668 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 79% of Vibration's written reviews are positive against 61% of Audio Memos's, so the app with the better star average is not the one people write more warmly about.

Vibration ships an update every 6 weeks, Audio Memos every 2 months. The most recent releases landed on September 23, 2026 and September 27, 2026 respectively.
