Native apps are built for specific platforms (e.g. iOS, Android, Windows Phone, etc.). They are built using platforms’ native SDK and development platforms and are able to use some of the specific features of the device – e.g. Camera, Volume controller, speaker, etc. The web-based apps (also web-apps) run within the mobile browser and are virtually web pages that imitate the look of a native mobile UI. Such apps are advantageous over native apps as they give the same user-experience on different smartphones. However, they can’t use some features of devices like native apps.
