y Notate?
I was looking for a simple & affordable mobile chess notations recording application for me and my kids to enhance our chess skills. Since I didn't find any, I created one for the Goodle Android platform. Main features of this application are:

a) Chess moves/notations are recorded and replayed correctly
b) Compliance with USCF rules for electronic Chess scoresheet

Why does it say somteimes Invalid move when I make a legal move?

In touchscreen mode, application recognizes the selection only when the button receives the touch event. Sometimes the button doesn't receive the event if the touch is on an adjacent button where the move would be illegal. If your device supports a trackball, please verify by clicking on the trackball. If you still see issues, please let me know.
