From ERS Computer Solutions Ltd:
This application is built and tested for iPhone not for iPad. We have plan to build this application for iPad later. InfoApp Manager 2013 has been designed for corporations, associations and businesses of all types to develop customised content for their target audiences and publish this instantly to their target audiences. It removes the complexity and expense involved in designing an App for your business and enables you to concentrate on the most important element, your content. All data published is cached locally on the device of offline viewing enabling people to review data without an internet connection. Forms can be published allowing users to complete and send the data back in structured formats. Documentation sets can be sent to target audiences for download review and signing.
