Verdict
The clearest difference is in-app purchases: SoundFlow at none against Knobbler's 3. SoundFlow also leads on review sentiment (100% vs 88%) and iOS requirement (11.0 vs 16.4). Knobbler's advantage is update cadence (every 9 days vs every 4 months) and rating (4.8 vs 4.6). On price, ratings volume, ads and device support there is nothing between them.

Knobbler holds the better App Store score, 4.8 against 4.6. Both are backed by a comparable volume of ratings — 10 and 16 respectively. Written reviews complicate that: 100% of SoundFlow's written reviews are positive against 88% of Knobbler's, so the app with the better star average is not the one people write more warmly about.
SoundFlow ships an update every 4 months, Knobbler every 9 days. The most recent releases landed on October 24, 2026 and October 21, 2026 respectively.
