 Watch Application System in Python
 ==================================
 
-Currently WASP is primarily useful as a pre-packaged MicroPython

+Currently in its infancy wasp-os provides nothing more than a simple

+keeps time well and has enough power saving functions implemented
+that it can survive for well over 24 hours between charges so even

 Bootloader. It has been extended to make it robust for development on
