# Spinn vs Cube Synth Pro

Spinn and Cube Synth Pro both sit at 4.5 stars, but that hides the real split: 80% of Cube Synth Pro's written reviews are positive against 50% of Spinn's. Cube Synth Pro also leads on price ($9.99 vs $15.99) and update cadence (every 2 months vs every 8 months). On rating, ads, in-app purchases and monetization model there is nothing between them.

Spinn costs $15.99 and Cube Synth Pro $9.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Spinn holds the better App Store score, 4.5 against 4.3. Both are backed by a comparable volume of ratings — 4 and 16 respectively. Written reviews complicate that: 50% of Spinn's written reviews are positive against 80% of Cube Synth Pro's, so the app with the better star average is not the one people write more warmly about.

Spinn ships an update every 8 months, Cube Synth Pro every 2 months. The most recent releases landed on September 30, 2026 and September 25, 2026 respectively.
