Keeping track of your games' score
Hello everyone. This is my first message here
I would like to know whether you keep track of your tennis games' score? I have started playing tennis recently and I am interested to know whether there is already an established way how to keep track of:
1. my tennis progress
2. opponents played against and the score I got
3. a way how to rank myself with regards to other players I play against
I was thinking of an XLS sheet but maybe there is a piece of software that does this more efficiently.
P.S. Apart from tennis I love technology and I work in IT.
