I am the Product Manager for the Mobile App Strategy at Ruckus Wireless. We continually are looking for ways to improve our product line, and while there isn't much work in a mobile app, there is a set of expectation that we continue to maintain and update them. This is a non trivial task especially as new versions of Android / iOS are built. One of the ways that we use to prioritize this work is to look at usage on the apps, and these apps, in particular weren't seeing much usage. Therefore, we decided to pull them from the stores.
If one of these applications (SWAT iOS, SWAT Android, Zapper iOS) is something that's critical to you, let us know, we're always open to feedback. Please make sure to specify which one.
