What is user experience in a mobile application?
Mobile app UX is the end-to-end experience and set of interactions users have with an app on handheld devices, including smartphones, tablets, and wearables. Note: the more general term 'mobile UX' refers to both app and website design, and is often used interchangeably between the two.
How long should an app load?
Statistically speaking, the ideal load time of an app should be 2 seconds. In fact, according to Google, 53% users abandon a mobile website that takes more than three seconds to load. This may be acceptable up to 5 to 8 seconds.
