Hello,
since the old days of Appeon Mobile, now PowerServer Mobile, the possibility to write PowerScript and deploy a mobile apps to iOS and Android devices has been a great plus to PowerBuilder developers. Clearly the ability do leverage full-fledged DataWindow presentation styles and functionality, as well support for the majority of PowerBuilder objects, has made the way to Mobile apps distribution as easy and quick as building a desktop application.
However, the PowerServer Mobile features are not "limited" to the regular PowerBuilder language.
A handful of additional API allows to control a wide range of builtin sensors and software functionality that are exclusive of smartphones and tablets. Among them, geolocation, maps, camera, barcode, e-payment, fingerprint recognition to name a few.
