App Description

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.
