RTA Audio Realtime analyzer with recording and Visualizer module with export. ••• Realtime analyzer ••• Realtime analyzer gives you the ability to analyze realtime audio input (built-in microphone or external audio accessory inputs) using Fast Fourier Transform with selected window function. You can also record the input for future offline processing or export. ••• Visualizer ••• This module presents you the results of offline audio analysis. Selecting previously captured recording gives the graph view, spectrogram and waveform of the audio data. Simple controls gives you the ability to play, loop, seek and change rate of the recording synchronized with analysis data presentation. Export function allows you to share or archive your analysis. Resulting PDF document contains basic recording information, spectrogram, peak & RMS graph and frequency table data with maximum peaks (with the time of the occurrence in recording) ••• Features ••• Resolution: 1/2 - 1/96 Octave Logarithmic frequency scale Fixed frequency range (20 - 20kHz) Tone scale view C₀- H₈ (A₄ = 440Hz) Peak hold graph Peak average graph RMS average graph Pointer (watch) function Peak and RMS input meter ••• Audio input specification ••• Audio session mode - measurement Input gain control Sample rate: 48000 Hz Bit depth: Float32 Channel: 1(mono) Frequency range: 20Hz - 20kHz Dynamic range: -100dB - 0dB ••• FFT (Fast Fourier Transform) specification ••• Frame size: 8192 Overlap: from 60% to 90% Smoothing Window: Bartlett-Hann, Blackman, Blackman-Harris (default), Blackman-Nuttell, Cosine, Flat Top, Gauss, Hamming, Hann, Lanczos, Nuttall, Rectangular, Triangular Hardware acceleration

Verdict
The clearest difference is rating: KRK Audio Tools at 4.1 against RTA Audio's 3.5. KRK Audio Tools also leads on in-app purchases (none vs 1) and iOS requirement (9.3 vs 15.6). On price, review sentiment, ratings volume and ads 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. RTA Audio sells 1 one-off in-app purchase. KRK Audio Tools asks for nothing beyond the download.
KRK Audio Tools holds the better App Store score, 4.1 against 3.5. Both are backed by a comparable volume of ratings — 32 and 40 respectively. Written reviews complicate that: 59% of RTA Audio's written reviews are positive against 54% of KRK Audio Tools's, so the app with the better star average is not the one people write more warmly about.
