Parallels Plesk Panel Mobile Manager  is a premium version of Parallels Plesk Panel Mobile Monitor which gives administrators access to the most important information about Panel servers and control over core administrative functions from selected smartphones. 
The app is free, but it requires a server running Parallels Plesk Panel 10.4.4 and Parallels Plesk Panel Power Pack in order to use it as intended.  Parallels Plesk Panel Mobile Manager connects only to Parallels Plesk Panel servers which have corresponding permission granted by their Panel license.

Parallels Plesk Panel Mobile Monitor is a free app that does not require Power Pack.  Compare both versions of this app at http://www.parallels.com/products/plesk/power-pack.
