Free download includes a simulated signal, not live microphone measurement. Spectrum Pro unlocks live measurement and Pro tools. U.S. prices: $6.99 per month, $49.99 per year, or $79.99 for a one-time Lifetime purchase. Monthly and annual plans renew automatically until canceled. Apple shows the current localized price before purchase. Existing Lifetime purchases remain honored. Phone and tablet microphones provide estimates, not certified measurements; Apple Watch is a remote for the iPhone microphone.
