Swift command is brilliant, now fitted to all swift caravans and motorhomes.
Really looking forward to using mine, primarily for checking my liesure battery over winter.
I'll be using both my smart phone and Nexus tablet for using the app.
Obviuosly there will always be those who struggle with technology, but you can still use the local control pads which you would have to learn to use anyway.
So its your choice, stand up to alter controls or sit with your feet up using a tablet.
