Professor Amanda Burls, a former director of the Critical Appraisal Skills Programme, has produced a mobile app called BestEvidence that enables users to get access to the best available evidence at the time it is needed. It works by accessing the TRIP database which searches many resources, including PubMed and the Cochrane Library. A special free CASP version of BestEvidence is available. To get this on your mobile phone open the web browser on your phone and go to www.BestEvidence.Info/CASP which will take you to the page where you can register an account. (BestEvidence can also be used on a table or desktop computer.) To get the BestEvidence icon to appear on your phone (so that you don’t have to go to your web browser every time) simple select “Add to home screen” from the browser’s menu so that it works like any other app.

We hope you find this useful. CASP checklists will be added to the notes section of the app over the coming months. We welcome feedback so if you have any problems, feedback or ideas for additional functionality, please email us at
