Not being able to set the limits of the frequency scale renders it unusable on a small screen for some tasks. ### 4/5 — 高機能・高性能 *2019-05-02* お勧めです。 ### 3/5 — No IAA / AudioBus support *2017-10-05* One of the nicest looking spectrograms around, unfortunately it only supports mic input. Does not work with AudioBus or AUM. ### 3/5 — Nice, but very limited. *2017-04-05, version 3.0* Smooth, as advertised, but no zoom, or pan of time or frequency feels like it's "just for show". Ok for that. Peak marker on spectrum would be nice. ### 2/5 — Great app but crashes on save *2016-09-19* Not good for much except pretty interface. No technical utility until developer fixes crash on save and allows export of files. Birders could really find this useful for ID of species if dev addresses these issues. Fine potential not yet realized. ### 2/5 — Mostly works *2016-05-29* It works, but could use a scale feature. Crashes when I try to save a picture - use screenshot hotkey as a workaround. ### 5/5 — Great App 😍 *2016-04-24* This app works great it ONLY crashes when if you try to save an image If you don't care for saving an image buy it I recommend it 👌🏼 Waiting on a Update 🙏🏼 this app is too Good Please UPDATE ### 2/5 — Amateur sound guy *2016-03-10, version 3.0* Makes a beautiful sound spectrogram but that's it. No pause, replay or making a spectrogram of a saved sound file. Limited. ### 4/5 — Ótimo *2016-02-19* Muito bom o app ja testei com o "aphex twin" e deu certo...eu recomendo👌🏻👍🏻 ### 5/5 — Nicely Done *2016-02-05, version 3.0* This app continues to amaze me and I am particularly pleased the Dev keeps the app updated. Get this app; I highly recommend it! ### 5/5 — Awesome *2015-08-05, version 3.0* Perfect. I just wish I could send out midi from the sonic data;)) ### 5/5 — Awesome *2015-08-04, version 3.0* This is my main analyzer, it works great! Used in multiple real-world applications... Love this app! ## Most critical reviews (10 lowest-rated) ### 1/5 — No ability to load an audio file? *2025-06-07* Buyer beware. Unless I’m missing something, there is no ability to load an audio file into this app, as quality of the demo seems to imply. This should be a basic function at this price. ### 1/5 — Developers have removed key functionality *2021-04-16* I purchased this years ago because it would display the electronic resonance carrier waves emitted by powerful RF emissions, like cell phone towers. Now, over the past year or so, the developers have deliberately removed these background resonance waves from being displayed; I can only guess why. I have emailed them twice with no response. I’m pretty sure they know what they did, and why. ### 1/5 — RPO *2019-03-25* Programmers took away the 16-20kHz frequencies. Can no longer see the Easter eggs in movies. ### 1/5 — App crashes when saving images *2016-04-02* This app crashes when I try to save an image. ### 1/5 — Stupid *2014-02-14, version 2.4* Dont waste your money this is a total fake. All it does is a slideshow of pictures. What a ripoff😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😠😠😠😠😠😠😠😠😠😠😠😠😠😠😠 ### 1/5 — Too much not to record! *2011-12-04, version 2.2* You can't record? Well there goes 4 bucks down the drain. Merry Christmas. ### 1/5 — Enttäuschend *2011-06-26* Man kann sich die Analyse aktuell aufgenommener Sounds ansehen. Das ist alles. Keine Aufzeichnung der Sounds. Keine Analyse von Aufnahmen oder Musik. Nicht einmal ein wiederholtes Hören bereits analysierter Sounds. Was soll man damit anfangen? Dafür ist es viel zu teuer!!! ### 2/5 — No way to zoom in? *2023-07-31* Useless to me if i can’t zoom in or in other words restrict the frequency range that it covers ### 2/5 — Meh *2020-12-27* It’s pretty good. It has a fast output, it reads sounds almost immediately. But there’s no playback and isolation option. I feel like that should be a basic feature in a pro version. ### 2/5 — Dangerous to leave open *2018-10-27* This app isn’t bad. I use it every day. But it lacks some spit-n-polish that a “pro” app should have. For example you get one - ONE - guideline. You cannot demarcate a range, you can only target one single frequency. The most glaring problem though, is if you leave it running in the background, even in paused mode, it will ravage your battery. An iPad Pro that normally lasts weeks on a charge is completely discharged within 3 hours even though the app was in the background and the iPad put to sleep. SO BE CAREFUL! The last update was a year ago, so this is likely as good as it gets. ## Most praised reviews (10 highest-rated) ### 5/5 — Excellent rta *2020-11-20* Excellent program, up until ios14.2. Unfortunately the app crashes apron loading on my iPhone XS Max. It’s useless now. Don’t update to 14.2 if you want to use this app ### 5/5 — Versatile real-time spectrogram *2020-10-17* It is fast, with easy-to-read and adjustable scales, colors and gain. I also like the frequency cursors! ### 5/5 — Perfect. *2020-10-13* Exactly what I've been looking for. You would not believe the number of apps I've scrolled through and looked at before I found this. I wanted a simple, clear, waterfall display type of spectograph that would give a visible record of the frequency and duration of certain transient sounds. There are apps out there that have this, but the ones I found were expensive, most requiring a monthly subscription or very high one off payment. This is just what I need & at a great price. I love the frequency measurement you can access by touching the sound trace, it helps enormously if I want to tune a notch or band pass filter in order to isolate a sound. many thanks, great app! :) ### 5/5 — Great for finding frequencies *2019-08-29* If you want to know if a high pitch squeal is coming from a device, this app is great for sniffing it out. Really fast update rate and UI response. Log vs linear is great for really dialing in higher or lower frequencies. ### 5/5 — Brings Science to singing *2019-01-27* Bio feedback for singers. Easy to use, immediate feedback for many aspects of singing. ### 5/5 — KILLER APP *2018-05-13* I don’t know Bode from booty, but this is the most perfect frequency app for anyone, musician or not, to explore the world around them. Buy now. ### 5/5 — Best app *2018-03-31* Pinpointed exactly what I was I looking for in seconds ### 5/5 — The best one.. *2017-09-13* The best spectrograph app, without a doubt. ### 5/5 — Super *2016-11-24* Super spectromètre, bonne résolution de la FFT, affichage fluide. J'aimerais plein de trucs en plus (zoom, pouvoir mieux paramétrer la correspondance niveau/couleur, etc) mais c'est déjà très bien. ### 5/5 — Best audio analysis app I've found *2016-11-14* The spectroscope, plus the sonogram on same screen with real time... perfect. Ability to drag a guide with note frequency? Even better... I'm using it with a cheap USB audio interface to viz my HW synths... If this could sit in audio bus, that would be really cool.. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
