iOS app development and interface design: Convertible has been available in the iOS app store since 2010. It was designed and developed by Douglas Buchanan and is now in its fifth major revision.

A noticable feature of the app is the distinctive interface which makes use of colour gradients to define borders with strong, understated textual elements.

The app has a number of carefully colour matched themes with names related to geographical locations around the world.
