No Excuses! Stockfish -> Email
One thing I know for sure about technology: There is NO excuse not to send a game to a chess coach, assuming the coach wants to see your games.
1) Enter the moves into Stockfish. Use analysis mode or “enter game” mode.
2) Save it. Email it to your Coach and maybe copy a parent or something. If you are using gmail, you will always have a backup copy.
Coaches:
Open the game in your gmail. Copy and paste the moves (the whole pgn) into ChessBase.
Stockfish is free (for now). There are other apps that let you use this workflow.
ChessBase and Fritz both allow you to copy and paste an emailed PGN file (see below).
There is one downside, but I don’t actually think it’s a downside. An incorrect notation sheet won’t work. So write down your moves correctly. And if you enter the game 12 hours or less after playing it (I made up this 12 hour rule just because it sounds smart) then the player can usually use his or her memory to figure out what happened. If you can only send 12 moves or so, that’s a LOT better than sending nothing.
