Yes. There is an iOS app available on the App Store called Letus Helix. It will work on iPhones 5s or later and iPads. The app is designed as a simplified version of the SimpleBGC GUI. It is designed to be a simpler way of modifying basic settings. Since it is intended to be much easier to use and understand, it does not include advanced functions of the SimpleBGC GUI.
A video explaining the use of this app can be found here.
