According to Google's statistics there are about 500 various Android devices currently on the market, each with its own Android version, hardware manufacturer’s additions, network operator’s modifications etc. Testing any application for such a variety of hardware and software combinations is very time consuming. To date many hours of active development and testing effort have been spent on NKCCluster. Other than testing in various emulated environments, this application routinely gets tested on a few actual physical devices, representative of commonly used devices on the market, each costing the author $$ (or £, or € or the equivalent in your local currency). And yet this application comes completely free, without even any irritating adverts so popular nowadays. Show your appreciation and help ensure the application remains so free by donating any amount of your choice via PayPal (please feel free to e-mail the author for other payment options).

Thank you!
