The GedFamilies app enables family files in GEDCOM format to be transferred from a PC to your iPhone, iPod Touch, iPad, Android phone or tablet, enabling them to be viewed and edited wherever you are. See http://www.telgen.co.uk/gedfamilies/ for details.

GedFamilies requires a companion program running on the PC to transfer family files to and from the iPhone, iPod Touch, iPad or Android device. This program, GedFamilies Sync, can be downloaded free of charge from here.

GedFamilies Sync transfers files using either a Wi-Fi network connection or a USB cable between the device and the PC.

To use USB transfer to or from an iPhone, iPod Touch or iPad, iTunes must be installed on the PC. It is also recommended that iTunes is installed when using a Wi-Fi transfer as this enables GedFamilies Sync to automatically detect when your device is ready for a transfer.
