Spectrogram Pro (with super-smooth 60Hz update) App Reviews

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

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..

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.

The best spectrograph app, without a doubt.

One of the nicest looking spectrograms around, unfortunately it only supports mic input. Does not work with AudioBus or AUM.

Pinpointed exactly what I was I looking for in seconds

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.

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.

It is fast, with easy-to-read and adjustable scales, colors and gain. I also like the frequency cursors!

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.

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

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.

Useless to me if i can’t zoom in or in other words restrict the frequency range that it covers
