The name is a lie, since it is not really "nation wide... Furthermore, their website is just terrible, and have to be completely redesigned in order to find any information whatsoever. Not recommended at all and by any means, but sometimes it's hard to find a good alternative.
I've been using this for a while, here is my review:
Good:
- Does not require a fast internet connection
- Is also viable on "mobile" devices such as phones or tablets (touch compatilitity)
- Accurate google-powered maps
Bad:
- Only banks in the UK
