musicMath is a musical tool that includes a timecode calculator, a tap tempo, a tempo to delay in millisecond and hertz converter, a note to frequency table converter, a sample length converter, a tempo change converter, and a frequency to note converter.

Timecode calculator:

• Add and subtract timecodes or frames
• Convert a number of frames to timecodes
• Simultaneously convert the number of frames and the timecode
• Conversion of timecode when changing the frames format
• Managing frames formats 23.976 fps, 24 fps, 25 fps, 29.94 fps, 29.97 fps, 29.97 fps drop frame, 30 fps, 50 fps, 59.94 fps, 60 fps

• Unlimited history calculations
• History can be saved and exported to other applications

Tap Tempo:

• Improved algorithm for imprecise tap
• Metronome
• Transfer calculated tempo to other musicMath tools

Tempo to delay table:

• Convert tempo to milliseconds and hertz
• Convert for whole-note, half-note, quarter-note, eighth-note, sixteenth-note, thirty-note and sixty-fourth-note for dotted notes and triplets

Note to frequency table:

• Convert Midi notes to frequencies
• Adjustable diapason and root note
• One hundred selectable temperaments
• Visualization of intervals in cents for each temperament
• Taking into account the temperament for the calculation of frequencies
• Plays piano sound when notes are touched

Sample length converter:

• Convert length between samples, milliseconds, and tempo

Tempo change converter:

• Calculates tempo change by ratio (%) and transposition

Frequency to note converter:

• Convert a frequency to the closest note and the cents needed
• Plays the frequency

C’mon guys!


This app is a great idea but what’s the point of updating for iOS 11 when the app still looks like it’s for iOS 5? It’s time for a major app facelift. Please!

Has potential


The app has potential. Things like the timecode and tap feature. If you are using the timecode feature there should be no need to enter a colon (:) or semi-colon (;). It should automatically format. Constantly having to enter it is annoying. The tap tempo feature needs improvement as well. It being iPad friendly is a plus though.

A must have for any audio engineer.


This app is a great tool for any audio engineer. You can easily tap out the tempo of songs when tracking and calculate out delay times when mixing. A must have for engineers.
