Tuna is a general purpose acoustic tool for musicians. Use the tuner to tune any musical instrument, from tubas, trumpets and other brass instruments, woodwind instruments such as saxophones, clarinets and flutes, to stringed instruments like violins and guitars. Tuna uses standard A440 tuning or select anywhere between A430 and A450. We have yet to find an instrument that doesn't work with the app.

Tuna has a metronome with both visual and audio cues. Select the number of beats per minute using the time selector, or tap a steady beat and Tuna will deduce the timing for you. Unlike traditional metronomes, Tuna allows you to enter complex accent patterns simply by typing in the number of beats between each accent - works well for both simple and complex time signatures.

Tuna enables you to visualise sounds. The spectrum analyser shows you the frequency content of sounds from 20 Hz up to 12 KHz depending on the microphone in your iPhone. You select the frequency range to display. (Surprisingly, watching bird songs is mesmerising!) Switch to the waveform view to visualise the sound waves.

And best of all, Tuna is stocked with tuna!

Designed by a musician for musicians.

Best metronome out there

Not being the most gifted at turning by year, this app really come in handy. App has all the features of a great metronome like audio and visual notification, many different tones, subdivisions, etc. only thing I dislike is that therea are no training mode for beginners but app is easy for use and this is not so critical

Fond of working with music

This app is a metronome. It is for musicians first of all, I am not a musician but I am fond of music and I like to work with it. I have never even heard about apps like this. It enables you to visualize sounds. With the help of this app you can tune any musical instrument from guitar to brass and wood wing instruments. Tuna is without any doubt my favorite application.

Fresh app for young generation

I'm an adult and got nothing to do with music at all, but my son is living with it. Playing on different instruments every day, he's already decided to be a musician in future. I'm just glad I found this nice app so he can setting up his sound quality even better now.
