A recent upgrade to this app has apparently led to some issues with the running of the device. If you find that you cannot access your existing BNF app, try uninstalling the app and downloading it again.
There is more information available from the website at NICE website at http://www.nice.org.uk/aboutnice/nicewebsitedevelopment/NICEApps.jsp
A reminder that the BNF app is freely available to all NHS Staff with an NHS Athens account. If you have not got an Athens account you can register online.
