Most application problems can be solved by either restarting the device or reloading the application from the app store.  If neither of these resolves your problem, and it is not addressed in this FAQ, then please email Support.

  • I downloaded the app and the app store says it's installed, but I can't find the icon.

This is not an app problem, and sometimes happens with certain devices.  Power down your device and then power it back up.  The app icon should now be visible.

  • Which mobile devices are supported?

The iOS version is universal and will run on an iPhone, iPod Touch, or iPad.   If you are using an iPhone or iPod Touch, some pages will view better in landscape orientation.  The Android version will run on any device using Android release 4.2 or later, including tablets.

  • Is there a limit to the number of articles that are downloaded?

NIH usually keeps most topics available for about three months, and they are all downloaded.  There is an application-imposed limit of the most-recent twenty articles per topic so that processing times do not become excessive in cases where there is a lot of content.

  • How do I share the content on Facebook or by email?

On the page you want to share, press the action button in the top right-hand corner of the page, then select email, Facebook, Twitter or any of the other social networks presented. On the Android version, sharing is by pressing the menu button on the screen you wish to share.

  • Can additional NIH content be added?

Yes. Send an email to  Support with the NIH RSS feed you think should be included, with a reason why, and it will be considered for addition.  Adding feeds would require an app update.
