SpectrumView provides a high-quality, real-time spectrogram and spectrum analyser display, with a configurable sample rate and frequency resolution. You can use this application to measure the highest tones you can sing, obtain visual feedback of the frequencies in your speech, identify an annoying sound, calibrate musical instruments and all sorts of acoustic analysis. Here's what it can do for you: · Refresh Spectrogram. Allows users to refresh the spectrogram so that it clears the spectrogram that had already been displayed. · Change min and max scale. Allows users to set their own minimum and maximum scale value on the spectrogram and spectrum analyser view, in both linear and log scale. · Set Recording filename. Recording filenames are editable and the suffix can be set to have an incremental value or date/time. · Generate snapshot of the spectrum data from playback and live recordings. [IAP] · Access recordings and snapshots using the "Files" app. All the data can be easily accessible using the "Files" app that is available from iOS 11. · Web File Transfer.

Never forget where a clip was recorded – uses the devices location services. · Auto lock disabled. During playback and recordings auto lock is disabled to prevent the device from automatically locking (if enabled), for uninterrupted recording/playback · Multiple selectable sample rates from 8,000 Hz to 48,000 Hz · High-frequency resolution with configurable signal analysis window lengths or Fast Fourier Transform (FFT) orders. · Sound intensity represented using a colour spectrum scale from -96 dBFS to 0 dBFS. · Frequency Pinch-to-Zoom. Allows you to zoom into the frequency space to look at a specific tone or frequency. [IAP] · Recording and Playback of Audio Files. Provides a fully functional audio recorder that allows you to record, pause and play back files in high-quality, uncompressed, wave format. · Tap Data Cursor. Allows taps on any part of the Spectrogram or Spectrum Analyser display to obtain the exact frequency in Hertz (Hz) and level in decibels (dB) at that point. · Musical Notes or Frequency Display on Tap. Selectable frequency or musical pitch notation to obtain the cent-accurate musical note e.g. A4 (22), when the display is tapped. · Live Spectrogram and Spectrum Analyser Views of Recorded Files. Files recorded can be played back and the Spectrogram and Spectrum Analyser modes can be used to review the audio. · Sharing Recorded Files by Email or iTunes File-sharing. · High Quality Screenshots. · *Improved* Soundcloud support.

Verdict
The clearest difference is review sentiment: SpectrumView at 63% against Vocal Range's 20%. SpectrumView also leads on ads (none vs shown) and iOS requirement (9.0 vs 13.0). Vocal Range's advantage is rating (4.5 vs 3.1) and update cadence (every 3 weeks vs every 10 months). On price, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. SpectrumView sells 7 one-off in-app purchases and Vocal Range sells 13 in-app purchases, starting at $4.49 per year. Whichever you choose, the download price is not the number that matters.
Vocal Range holds the better App Store score, 4.5 against 3.1. Both are backed by a comparable volume of ratings — 74 and 307 respectively. Written reviews complicate that: 63% of SpectrumView's written reviews are positive against 20% of Vocal Range's, so the app with the better star average is not the one people write more warmly about.
SpectrumView ships an update every 10 months, Vocal Range every 3 weeks. The most recent releases landed on September 21, 2026 and September 22, 2026 respectively.
