EBSCOhost is optimised for mobile devices so a mobile app is not required, (however, apps are also available).
This link provides direct access to the EBSCOHost mobile responsive page. Choose which databases to search, then limit and sort results. Get full text results in HTML/PDF, save and email for later offline access.
With JSTOR you can email citations to yourself to read articles later.
JSTOR’s interface automatically adapts to the screen size of a device without requiring a separate mobile URL or any device configuration. Just go directly to www.jstor.org on a smartphone or tablet, and the screen will adjust accordingly!
Browzine is a tool that allows you to access and keep up to date with key journal titles that the Library subscribes to in your subject area. You will need to log in using your University ID and password.
