This a demo.  It doesn't expire but some of the features are limited:

• Only the first 7 frets can be used.
• The training mode can only be used for 3 minutes per session.
• The game mode is limited to the first 4 levels.
• Statistics and preferences aren't saved between sessions.
• However the tuner is fully functional
