I'd love to but I don't like Apple's restrictive practices.
To build an iPhone app, I need to:
* Purchase a MacBook Pro
* Purchase XCode
* Purchase an App Store publishing license
* Build an app
* Submit to the App Store and hope Apple Gods will approve my app
* Like to use a System76 Ubuntu (XFCE) Laptop
* Like to work on open source platforms
I have nothing against iOS app developers. This app is open sourced, feel free to clone it!
