Understandably, the OP like others doesn't necessarily understand why rewriting a Delphi app for Android just isn't possible.
But let me frame the request differently: if Alt.Binz had an API for remote access and control, would the OP or anyone else write an Android/iOS/WindowsPhone app for it? I'd be quite interested to know if there's any potential demand out there for such 3rd-party DIY integration with Alt.Binz.
When I say API, I mean along the lines of
this.
