Spectrum Pad turns your iPad, iPhone, or iPod Touch into an audio spectrum analyzer. Frequencies up to 20 kHz can be displayed. You can control the displayed frequency span, as well as the FFT size, from 1024 to 262144 bins. A logarithmic display of the entire 10 Hz to 20 kHz frequency range is available, and the graph fill mode can be turned on and off, as well as the display of up to five frequency markers. Filtering (averaging) can be applied to the spectrum, to smooth out variations. You can turn on the Peak Hold to make it easier to see transient events, as well as adjust the decay rate. Swiping with two fingers lets you adjust the brightness of the spectrum or the graticule grid overlay. Tapping three times with two fingers will save a screenshot to your Photos. One of several user selectable window functions can be used: Rectangular Hanning Hamming Tukey Cosine Lanczos Blackman

Verdict
The clearest difference is price: Meshtastic at Free against Audio Spectrum Analyzer's $3.99. Meshtastic also leads on update cadence (every 10 days vs every 7 months) and rating (4.2 vs 3.9). Audio Spectrum Analyzer's advantage is review sentiment (54% vs 44%) and iOS requirement (6.0 vs 17.5). On ads, in-app purchases 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
Meshtastic is free to download; Audio Spectrum Analyzer costs $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Meshtastic holds the better App Store score, 4.2 against 3.9. That said, the two scores are not equally well evidenced: Meshtastic has 803 ratings behind it against 52, so its average is the more settled of the two. Written reviews complicate that: 54% of Audio Spectrum Analyzer's written reviews are positive against 44% of Meshtastic's, so the app with the better star average is not the one people write more warmly about.
Audio Spectrum Analyzer ships an update every 7 months, Meshtastic every 10 days. The most recent releases landed on September 30, 2026 and September 27, 2026 respectively.
