Why We Recommended It
Audio / Spectrum Analyzer is currently free on iOS, making its professional-grade real-time audio analysis accessible to everyone. Unlike most utility apps in the productivity space, this tool packs a full suite of FFT-based spectrum, spectrogram, and waveform displays that are typically found only in expensive desktop software. Whether you're an audio engineer tuning a PA system, a musician checking instrument harmonics, or a podcaster optimizing room acoustics, you can now monitor microphone input with selectable FFT sizes, window functions, and frequency weighting (dBA/dBC). The app also includes octave analysis, peak hold, and internal signal generation for testing. Its interface adapts to portrait and landscape orientations, and the three-panel layout lets you view waveform, amplitude spectrum, and time-frequency spectrogram simultaneously. Normally priced at $10.99, this is a rare chance to grab a powerful analysis tool for nothing. Grab it while the deal lasts and elevate your audio workflow without spending a dime.

Everything works as intended with a lot of customization but what would be really nice is a way to change the sampling rate to make measurements more readable.
