FamilyBee is advertised as "an industrial strength family tree browser. Allows viewing of all details for individuals and families in GEDCOM genealogy files." The beta test version is available free of charge although it will stop working some day. The developer expects that, once the beta is complete, the regular version will sell for $10.
The author would appreciate feedback from genealogists.
FamilyBee can be obtained from "Android Market" on the Android phone.
I don't have an Android phone so I can't test this. If anyone uses the beta for a while, please let me know of your experiences with it. Thanks!
