VOCALOID first is an iOS app released by Yamaha.
The app offers an easy to use method of writing songs on the go. The app itself is free but additional content is paid for. It allows for easy creation and uploading to YouTube.
It works with the iPhone4S, iPhone5 and iPod touch.
The vocals held by the app, are powered by a basic version of the VY1 vocal. However, despite the poor quality of this version of the VY1 vocal, at the time of release, this was the first fully working "free" version of VOCALOID™.
It also had the ability to connect to the VOCALOID NET
