SWIFTSCALES Perfect Pitch Pipe

This is a wonderful app. I don’t like the harsh tones in other pitch pipes. This app has a nice mellow sound in the pitch. I love the pro upgrade. It’s a blessing to have this wonderful pitch pipe. I hope the developers will know I’m truly grateful.

Great sound and volume. Very attractive and intuitive interface. Tasteful ad support in the free version. I’ll definitely be using this to lead congregational singing!

I didn't check with an oscilloscope, but I'm quite sure the pitch is off by almost a quarter note in some places.

I downloaded this app because it's hard to find a vocal warmup app that caters to a 3+ octave range and I thought I'd be able to set my own range for the exercises. It only let me set the low note and then the audio didn't work for any of the drills. Useless app.

I love this app. So many awesome features and super easy to use. The other pitch pipe apps are horrible and terrible quality this is the only super professional super high end one!!
