All recent versions of ohmiGene work when installed on a USB jump drive containing a working folder with the three versions of ohmiGene (MacIntel, PowerPC or Windows). ohmiGene is immediately operational, all three versions sharing the same database. Your data is then portable and can be used from most any computer without installing anything to the computer's hard drive.
ohmiGene Lite is available free of charge but is limited to 509 persons in the database.
ohmiGene PLUS sells for $40 US and handles databases of unlimited size.
