WHAT NAMILIUM IS A real-time audio analyzer for measuring sound, seeing it, and singing with it. Spectrum, spectrogram, oscilloscope, loudness metering, and now a voice tuner, with no extra purchase. FFT sizes up to 32768 (about 1.5 Hz resolution). No account, no ads, no tracking. WHO IT IS FOR - You want your stream or podcast to sit at the right level - You want to check how a room or a speaker actually sounds, in numbers - You want to see whether you are singing in tune, not just hear it - You want to keep the tune you just hummed as written notes - You want to watch how sound works while you learn it GETTING STARTED Open the app, turn on the mic, and whatever is around you is drawn as it happens. Load an audio file to watch a track you like. Play a sine tone or a sweep from the signal generator to check gear or a speaker. Switching views and adjusting the details both live in the control panel. WHAT YOU CAN DO Measure - Spectrum: A and C weighting curves, 1/1 to 1/12 octave band bars, or a continuous curve. You can load a correction curve for a measurement mic (FRD format) - Loudness: BS.1770 LUFS (momentary, short-term, integrated), loudness range, and true peak with 4x oversampling, useful for matching levels for streaming or podcasts - dB SPL: pair a measurement mic with its correction curve to read sound pressure levels - Snapshots and CSV: keep the current shape to compare against, or export the numbers to work on elsewhere - Multi-resolution analysis: fast response up high, fine detail down low See - Spectrogram: how frequencies move over time. Pinch to zoom in time or frequency, and freezing recomputes the visible range. The axis can be linear, logarithmic or mel, and you can overlay the three peaks that shape a vowel sound - Waterfall: your spectrum history as a 3D landscape - Oscilloscope: Auto and Normal triggering holds the waveform still, with a ms/div time base you can pinch to zoom - Phase Scope: stereo width and phase on a Lissajous display, with a correlation meter for mono compatibility - Crosshair readout: exact frequency, time and level under your finger Sing - Voice tuner: sing and your pitch flows across the screen as a line, with the note you are on spelled out. Set a target note and you can see whether you are on it, close to it, or off - Transcription: what you sing is written down as notes. Export as MIDI and the tune you just hummed goes straight into your DAW. The audio and the raw numbers come along too - Click and beat: keep time while you sing and the exported notes line up to the bar. Freeze the display and zoom in to find where it drifted Input and output - Input: the built-in mic, a Bluetooth mic, or your own audio files - Signal generator: sine tones and sweeps for testing - Screen capture: save or share any analyzer view as an image WHAT MAKES IT DIFFERENT - It works entirely on your device. Your audio is never sent anywhere - Nine themes including Neon and Ocean, plus custom themes you design yourself, and an optional rainbow that flows across the frequency axis

Verdict
The clearest difference is rating: NAMILIUM at 5.0 against MintFFT's 4.7. MintFFT's advantage is ratings volume (6 vs 1). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
NAMILIUM holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: MintFFT has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
MintFFT ships an update weekly, NAMILIUM every 9 days. Both last shipped on October 24, 2026.
