Sing. Shape. Share.


Vio is an immersive vocal experience. Vio 2.0 has been completely redesigned for iOS 7 and is now free!

This incredible update includes a new interface that’s more beautiful and intuitive. We've added four new background color palettes. Additionally, Vio is now fully optimized for iOS 7 and is free to download and explore. Once you discover how amazing Vio is, you can purchase a bundle of 19 audio presets and 16 more color palettes in Vio's new in-app store.


Vio pushes vocal processing on the iPhone and iPad to new levels. From futuristic to fuzzy, 8-bit to outer space, Vio’s presets are all waiting to be explored.

Vio's new interface makes the visual experience of transforming your voice a beautiful one, too. Set the mood using one of Vio’s new color palettes. Then, pinch, drag, swirl and swipe to discover new transformations and shape new sounds.

Whether you're an award winning crooner or bus stop amateur, Vio's pitch correction technology ensures that every note is in tune and every melody beautifully harmonized.

Adjustable keys, scales, tempos and more allow you to tailor your presets and define your own sound.

Low, medium and high quality audio formats make it the perfect tool for every situation: time-killing and studio recording alike.

Once that perfect melody has been dropped, turn on Vio’s Looping feature. A double-tap on the screen begins a loop of your recording, leaving you free to focus on shaping your sound with the visualizer.

Easily share your performances and playful voice messages with friends and family via iMessage or text, email, SoundCloud, Dropbox, YouTube and Vimeo.

Used to work like a gem

It was my favorite music app of all time works great on my iPod but it won't work on my new iPhone at all. I mean I will be singing and press the done recording and you can't hear anything I sang it's the saddest thing because I bought all the voice filters and now I can't use them... anymore. It's just sad,and disappointing I give four stars for the quality I used to have on my 5th gen. iPod but would reduce it to three maybe two stars for not working at all on my iPhone 6s.

Makes voice sound amazing only reason I'm not giving 5 stars is cause I just started using it today but everything seems to work in my opinion one of the best vocoders on the App Store

Luv at First Sight,... Uh, Song!

This app is incredibly cool. Go head and get in touch with your inner T-Pain or Gospel Choir compositions. The only thing I think that could make this even better is if it had a blend control between the dry mic sound and the effect itself. Then you could record and playback that mix to see exactly how you sound. With a little trial and error, it could or would be just what you might be looking for.
