Yapp has two major products Yapp Online Editor, a template-based editor on the web and Yapp app, hosted on users’ mobile devices through the mobile app Yapp. When apps are published, they are attached to a link that can be used to download the app on a mobile device. The apps are not published to the iTunes or Google Play app stores directly and are downloaded using a shortlink generated from the online editor. Yapp's online editor and mobile app are built using Ember.js, an open-source JavaScript application framework.
