ToneCalculator helps you bring your songs in tune. Finding the right tempo that fits best to your song.

When something swings below 20 Hertz we can’t hear the frequency but perceive it as rhythm. So the tempo is a frequency below our hearing range, but still a frequency that is either in tune or not.

A big part of music feeling natural is having every part of the arrangement and environment being in sync with the other elements surrounding it. So ToneCalculator also provides you with the correct (in sync) data for your Delays, LFOs, pre delay times of your reverb, attack and release times of compressors and other envelops.

ToneCalculator comes with a Fretboard window to show you the note and chords on the fretboard of your instrument including:

Guitar, Baritone Guitar, Banjo (4 String, 5 String + Tenor), Bass, Cello, Fiddle / Violin, Mandobass, Mandolin, Pedal Steel Guitar, Ukulele (Baritone, Bass + Soprano), Vihuela and Viola.

You can also see how the scale looks on the fretboard in different tunings! 84 different tunings are included.

ToneCaluclator comes with the following scales:

Chromatic, Major, Minor, Major Pentatonic, Minor Pentatonic, Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian, Locrian, Super Locrian, Melodic Minor, Dorian b2, Lydian Augmented, Lydian Dominant, Aeolian Dominant, Half Diminished, Major 5, Dorian 4, Phrygian Dominant, Lydian 2, Altered Dominant bb7, Harmonic Minor, Locrian 6, Harmonic Major, Dorian b5, Phrygian b4, Lydian b3, Mixolydian b2, Lydian Augmented 2, Locrian bb7, Diminished, Dominant Diminished, Whole Tone, Augmented, Inverted Augmented, Neutral Pentatonic, Minor Blues, Major Blues, Algerian, Arabian, Byzantine, Chinese, Egyptian, Hindu, Hungarian Minor, Javaneese, Persian, Scottish, Spanish 8 Tone, Klezmer, Japanese or create and save a custom scale.

Get This One!

This is SO much more than a simple metronome app. This free application is so incredible that I paid $6 in support just to say thank you (THANK YOU!).

The metronome portion is easy to understand and operate, but this developer has gone FAR above and beyond anything I ever imagined would come from a metronome.

Also, regardless of the other features, this is the best free metronome app in the App Store. I already tried the other ones on here, and they're either lousy or they try to force you to buy the full version in order for it not to be lousy. I think it is probably very safe to say none of the paid apps could even compare to this one, anyways.

The special features of the app display a whole host of advanced calculations, having to do with the mathematical relationships between pitch frequencies (notes/tones) and musical tempos.
Some of these things I had already attempted to calculate on my own, with marginal success... but was nice to confirm some of my work, and then view many more elements I wasn't even sure how to calculate.

This marvelous developer has made a tremendous effort in providing such a richly featured application.

Just getting started

This thing has so much functionality I may never get thru it all. But it works great. What a great tool for learning about music. And customer service is exceptional.

Thank you for your rating!

stays in focus even when you move to other apps : (

Good: Tap tempo, start/stop via hitting “m”; fairly easy interface, albeit cluttered; other nice-to-have features for a metronome.
Bad: App’s main window emains “in front” even when you select other apps. It should “go back.” Essentially, you have to quit it to make its window go away so you can see any other app. This is a dealbreaker for me, if developer could fix this I’d happily pay for the app.
Also would prefer if it didn’t make a sound when you hit tap tempo. As a piano teacher I use metronome apps to tap a student’s tempo without them getting distracted by hearing a click. I don’t want to have to turn the volume down to tap tempo, only to turn it back up when I want the Metronome. AFAIK, there’s really no need for Tap Tempo to ever make a sound for anyone.

Thanks for your comment. You can choose now in the latest version, if you want Tap Tempo without sound and if you want ToneCalulator to behave like a normal window.
