Both the website and apps allow you to search for your nearest facility or by town/postcode before you travel, but:-
1) The websites give more information and more options and are specifically designed for when you are using a laptop or desktop computer. Use the website to find out the details and plan your route before you leave home.
2) The free Apple or Android phone apps work better when you are using your tablet or smartphone. Use the phone apps to get there and then find their exact location.
We have spent the last 4 years creating and checking the Changing Places/Space2Change guides, which are by far the most comprehensive and accurate ones available in the UK.
Things are always changing though, so if you find any omissions or errors PLEASE TELL US and we will correct the databases!! You can easily do this on the websites and apps.
