An application represents a single mobile app. An appID & secret key is generated for the application that is needed to integrate the Sentiance SDK into a mobile application.
Head over to developers.sentiance.com/apps
Use the "Add app" button to add a new application
It's a good practice to use the same application name as in the App Store / Play Store
Save your changes
You will now have an appID & secret key ready for integrating the Sentiance SDK into your mobile application
