Qrayon released Cardflow 2.1 for the iPad, a major update to their popular digital index card App. Cardflow 2.1 adds major new features including the ability to insert links to web pages and online videos, and create tappable hotspots to navigate between cards. This can be used for mind-mapping and to create interactive experiences without any coding. Links continue to work in exported PDFs, which can be shared with colleagues and friends. Cardflow is Free and can be downloaded from iTunes.
