Compás Builder's advantage is rating (5.0 vs 4.6) and update cadence (every 2 months vs every 4 months). On ads, monetization model and iOS requirement there is nothing between them.

Cube Synth costs $1.99 and Compás Builder $24.99 up front. Compás Builder sells 3 one-off in-app purchases. Cube Synth asks for nothing beyond the download.

Compás Builder holds the better App Store score, 5.0 against 4.6.

Written reviews complicate that: 89% of Cube Synth's written reviews are positive against 67% of Compás Builder's, so the app with the better star average is not the one people write more warmly about.
