The following announcement was written by the folks who produce GedStar Pro:
GedStar Pro, an app that supports detailed viewing of the data from your PC-based genealogy program on an Android smartphone or tablet, is now a completely free product (formerly cost $9.95). The app consists of a Windows program that converts data by directly extracting it from a Master Genealogist or Legacy Family Tree database, or by reading a GEDCOM file, and making it available for the Android app to display. Viewing options and other features are extensive, including a relationship calculator, graphic tree views, photos, and more.
The app will continue to be developed and updated for the foreseeable future, but with possibly a lower level of support. The main reason is simply age: both of the developer and the software packages used to develop it.
