Spyrix offers a clear layout and user-friendly interface (I personally thought that other keyloggers offer a more aesthetically pleasing design) and the standard keylogging/monitoring capabilities. The program is invisible and well-disguised to an unknowing user and allows for remote monitoring. Additionally, even non-printed keystrokes are recorded. One can test out the keylogger for a free 5-day trial.
The downside of Spyrix is that it is only available in English, some screenshots come out all white, and sometimes the program crashes. Additionally, the report features are very limited - you can only search reports by keyword, and reports can only be sent via email. If you're looking for a stable keylogger with the features that meet your needs, the Perfect Keylogger is the solution.
