The present invention provides systems and methods for providing cross-device native functionality for a native app. More specifically, the invention is directed to a JavaScript Object Notation (JSON) data exchange format for use with a native app running on a user's mobile device, wherein the exchange format is configured to improve user experience and interaction with the app. The present invention may be particularly useful in a mobile-based crowdsourcing platform in which data is continually exchanged between remote user devices and a cloud-based service for collecting and managing user-driven data based on user interaction with native apps on their devices.
