What it does
Everything you need to see sound
Point it at anything — your voice, an instrument, the room — and watch the frequency spectrum scroll by in real time.
Live spectrogram
A smooth, GPU-rendered waterfall built on an 8192-point FFT, scrolling in real time as sound comes in.
Chromatic tuner
Instant note name, cents offset, and exact frequency — accurate enough for tuning any instrument.
Tempo & BPM
Onset detection estimates tempo from a steady beat, with a chip that pulses in time.
12 color palettes
Turbo, Plasma, Prism, and more — including palettes that react live to the beat or the note you're playing.
Bloom, sparkles & CRT
Optional visual effects layer glow, peak particles, and a retro shimmer on top of the waterfall.
100% on-device
No network access, no analytics, no account. Every bit of analysis happens locally and nothing is ever recorded.
Make it yours
A palette — and a personality — for every sound
New
Hands-free with Siri

New
Now a plugin for your DAW
Inspectro ships with a real Audio Unit (AUv3) extension — insert it as an effect in GarageBand, Logic Pro, AUM, or Cubasis and get the exact same live waterfall, palette, and readouts, right inside your session.
It's a true pass-through: your audio is only visualized, never altered. Settings stay in sync with the main app automatically.
Built for iPad
A layout that uses the space
On iPad, Inspectro trades the phone's floating buttons for a persistent inspector panel — the tuner, BPM, effects, and every palette, always in view alongside the waterfall.
Privacy, by construction
Nothing to collect. Nothing to leak.
Inspectro has no server, no analytics SDK, and no account system. Audio never leaves your device — it's analyzed and immediately discarded.
