# synthQ vs Fluss

The clearest difference is rating: Fluss at 4.8 against synthQ's 4.2. Fluss also leads on ratings volume (71 vs 13) and device support (3 vs 1). synthQ's advantage is price ($5.99 vs $13.99). On review sentiment, update cadence, ads and in-app purchases there is nothing between them.

synthQ costs $5.99 and Fluss $13.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Fluss holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: Fluss has 71 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 80% of synthQ's written reviews are positive against 78% of Fluss's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on October 1, 2026 and October 25, 2026 respectively.
