The Splunk Mobile App & Server is all about showing splunk dashboards, reports, and alerts on mobile device. There are another 2 mobile related offering from splunk: the Splunk SDK for Java, C# and other programming languages allow you to send data to splunk or search from splunk in your mobile app. Bugsense, which was acquired by Splunk in 2013, provides iOS/Android/WP SDK for you to track app crash, usage, and custom events. Those data are sent to BugSense cloud service and visualize on the web portal. In next few months, there will be a new offering from the BugSense team, to better integrate such mobile data collection with Splunk Enterprise.
Putting in short
Let me know if you encounter any issue.
