# Buffer vs Sonix app

The clearest difference is in-app purchases: Sonix app at none against Buffer's 12. Sonix app also leads on review sentiment (67% vs 55%) and iOS requirement (15.6 vs 18.0). Buffer's advantage is rating (4.7 vs 4.3) and ratings volume (34K vs 6). On price, ads and device support there is nothing between them.

Both are free to download. Buffer sells 11 in-app purchases, starting at $5.99 per month. Sonix app asks for nothing beyond the download.

Buffer holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Buffer has 34K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 55% of Buffer's written reviews are positive against 67% of Sonix app's, so the app with the better star average is not the one people write more warmly about.

Buffer ships an update weekly, Sonix app fortnightly. The most recent releases landed on September 26, 2026 and September 10, 2026 respectively.
