# Oscilloscope vs Sound Spectrum Pro

The clearest difference is rating: Sound Spectrum Pro at 5.0 against Oscilloscope's 4.1. Sound Spectrum Pro also leads on price ($12.99 vs $19.99) and update cadence (every 9 days vs every 8 months). Oscilloscope's advantage is ratings volume (19 vs 1). On ads, in-app purchases, monetization model and device support there is nothing between them.

Oscilloscope costs $19.99 and Sound Spectrum Pro $12.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Sound Spectrum Pro holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: Oscilloscope has 19 ratings behind it against 1, so its average is the more settled of the two.
