RasPi Check shows you overclocking information (frequency, temperature, volts) and more system information (free memory, runtime, disk status). You can also restart or halt your Raspberry Pi ® and send custom commands!
If you always want to keep an eye on your Pi there's also a widget for your homescreen.
All you need for the app to work are your SSH login credentials. You can either authentificate via password or via private/public key.
'RasPi' is one of the Rasberry Pi ® abriviations. For more information visit http://www.raspberrypi.org. Raspberry Pi is a trademark of the Raspberry Pi Foundation.
