4 stars: It has a really useful 'my agenda' facility to allow me to choose the sessions i want to attend, and access their details quickly without having to trawl the extensive agenda. I'm not sure the note taking functionality is fully there yet: there doesn't seem to be an option to save under anything other than general notes. I've not explored the exhibition side yet, but the conference part is helpful.
3 stars: Contains useful information from the ECCA website, including abstracts that can be read offline. Some buttons don't seem to work and either give error messages or cause the app to freeze.
